A lightweight dart to native super channel plugin, You can use it to invoke any native code directly in dart code. 5 | 6 | Supported Platform(Language): 7 | 8 | - iOS(Objective-C) 9 | - Android(Java) 10 | 11 | The primary scenario: 12 | 13 | - Implement some simple channels directly in dart code; 14 | - Native code that are calling using dna can also be hot-reloaded. 15 | 16 | 17 | ## Add dependency 18 | 1. Add folllowing code to the *pubspec.yaml* file in your flutter project: 19 | 20 | ``` 21 | dependencies: 22 | dna: 23 | git:git@github.com:Assuner-Lee/dna.git 24 | ``` 25 | 26 | > Reference: [https://flutter.dev/docs/development/packages-and-plugins/using-packages](https://flutter.dev/docs/development/packages-and-plugins/using-packages) 27 | 28 | 2. import header file in dart code: 29 | 30 | ``` 31 | import 'package:dna/dna.dart'; 32 | ``` 33 | 3. add gradle dependency in Android project: 34 | 35 | ``` 36 | implementation 'me.ele:dna-annotations:1.2.0' 37 | annotationProcessor 'me.ele:dna-compiler:1.2.0' 38 | ``` 39 | 4. add following conconfiguration in Android project's proguard-rules 40 | 41 | ``` 42 | -keep class **.Dna_Class_Proxy { *; } 43 | -keep class me.ele.dna_compiler.** { *; } 44 | -keep class me.ele.dna.** { *; } 45 | ``` 46 | 47 | ## Usage 48 | 49 | ### Main class 50 | 51 | - `NativeContext`: You can use it to describe *Native code* by *Dart code*, then call `context.execute()` to execute the final *Native code* on associated platform and get the returned value. 52 | 53 | - `NativeObject`: Used to identify the *native variable*. The caller `NativeObject ` can call the `invoke` method to pass in the *method name* and the *parameter array args list* in the context of the `NativeContext` to get the return value `NativeObject` object. 54 | 55 | 56 | The API of `NativeContext` is consistent. Now we will make a detailed introduction for call *ObjC* using `ObjCContext`, Then call *Java* using `JAVAContext`. 57 | 58 | ### Call ObjC using Dart 59 | 60 | `ObjCContext` is the final executor on iOS platform. 61 | 62 | #### Context call supported 63 | ##### Returned value as caller 64 | 65 | ObjC code 66 | 67 | ``` 68 | NSString *versionString = [[UIDevice currentDevice] systemVersion]; 69 | // Return versionString using fluter channel 70 | ``` 71 | Dart code 72 | 73 | ``` 74 | ObjCContext context = ObjCContext(); 75 | NativeObject UIDevice = context.classFromString('UIDevice'); 76 | NativeObject device = UIDevice.invoke(method: 'currentDevice'); 77 | NativeObject version = device.invoke(method: 'systemVersion'); 78 | 79 | context.returnVar = version; // Can be omitted, See:Quick use of instantiated objects in JSON supported 80 | 81 | // Get native execution results directly 82 | var versionString = await context.execute(); 83 | ``` 84 | 85 | ##### Returned value as parameters 86 | 87 | ObjC code 88 | 89 | ``` 90 | NSString *versionString = [[UIDevice currentDevice] systemVersion]; 91 | NSString *platform = @"iOS-"; 92 | versionString = [platform stringByAppendingString: versionString]; 93 | 94 | // Return versionString using fluter channel 95 | ``` 96 | Dart code 97 | 98 | ``` 99 | ObjCContext context = ObjCContext(); 100 | NativeClass UIDevice = context.classFromString('UIDevice'); 101 | NativeObject device = UIDevice.invoke(method: 'currentDevice'); 102 | NativeObject version = device.invoke(method: 'systemVersion'); 103 | NativeObject platform = context.classFromString("NSString").invoke(method: 'stringWithString:', args: ['iOS-']); 104 | version = platform.invoke(method: 'stringByAppendingString:', args: [version]); 105 | 106 | context.returnVar = version; // Can be omitted, See:Quick use of instantiated objects in JSON supported 107 | 108 | // Get native execution results directly 109 | var versionString = await context.execute(); 110 | ``` 111 | 112 | #### Chaining calls supported 113 | 114 | ObjC code 115 | 116 | ``` 117 | NSString *versionString = [[UIDevice currentDevice] systemVersion]; 118 | versionString = [@"iOS-" stringByAppendingString: versionString]; 119 | 120 | // Return versionString using fluter channel 121 | ``` 122 | 123 | Dart code 124 | 125 | ``` 126 | ObjCContext context = ObjCContext(); 127 | NativeObject version = context.classFromString('UIDevice').invoke(method: 'currentDevice').invoke(method: 'systemVersion'); 128 | version = context.classFromString("NSString").invoke(method: 'stringWithString:', args: ['iOS-']).invoke(method: 'stringByAppendingString:', args: [version]); 129 | 130 | context.returnVar = version; // Can be omitted, See:Quick use of instantiated objects in JSON supported 131 | 132 | 133 | // Get native execution results directly 134 | var versionString = await context.execute(); 135 | ``` 136 | 137 | 138 | > **Something about the final returned value of the `context`** 139 | 140 | > `context.returnVar` is the marker of the final returned value of `context`. 141 | 142 | > 1. When setting `context.returnVar`, you can get the *Native* variable corresponding to the `NativeObject`; 143 | > 2. Without setting `context.returnVar`, execute to the last `invoke`, if there is a return value, it will be the final returned value of `context`; if not, it will return a `null` value. 144 | 145 | > ``` 146 | > ObjCContext context = ObjCContext(); 147 | > context.classFromString('UIDevice').invoke(method: 'currentDevice').invoke(method: 'systemVersion'); 148 | > 149 | > // Get native execution results directly 150 | > var versionString = await context.execute(); 151 | > ``` 152 | 153 | #### Quick use of instantiated objects in JSON supported 154 | 155 | Sometimes, we need to directly instantiate an object with `JSON`. 156 | 157 | ObjC code 158 | 159 | ``` 160 | ClassA *objectA = [ClassA new]; 161 | objectA.a = 1; 162 | objectA.b = @"sss"; 163 | ``` 164 | 165 | Dart code 166 | 167 | One way 168 | 169 | ``` 170 | ObjCContext context = ObjCContext(); 171 | NativeObject objectA = context.classFromString('ClassA').invoke(method: 'new'); 172 | objectA.invoke(method: 'setA:', args: [1]); 173 | objectA.invoke(method: 'setB:', args: ['sss']); 174 | ``` 175 | 176 | The other way 177 | 178 | ``` 179 | ObjCContext context = ObjCContext(); 180 | NativeObject objectA = context.newNativeObjectFromJSON({'a':1,'b':'sss'}, 'ClassA'); 181 | ``` 182 | 183 | ### Call Java using Dart 184 | 185 | `JAVAContext` is the final executor on Android 186 | platform, it has all the fetures that `ObjCContext` have. 187 | 188 | - Context call supported; 189 | - Chaining calls supported; 190 | - Quick use of instantiated objects in JSON supported. 191 | 192 | In addition, it additionally supports the instantiation of an object from the constructor. 193 | 194 | #### The instantiation of an object from the constructor supported 195 | 196 | Java code 197 | 198 | ``` 199 | String platform = new String("android"); 200 | ``` 201 | 202 | Dart code 203 | 204 | ``` 205 | NativeObject version = context 206 | .newJavaObjectFromConstructor('java.lang.String', ["android "]) 207 | 208 | ``` 209 | 210 | ### Fast organization of dual platform code 211 | 212 | We provide you with a quick way to initialize and execute context: 213 | 214 | ``` 215 | static Future traversingNative(ObjCContextBuilder(ObjCContext objcContext), JAVAContextBuilder(JAVAContext javaContext)) async { 216 | NativeContext nativeContext; 217 | if (Platform.isIOS) { 218 | nativeContext = ObjCContext(); 219 | ObjCContextBuilder(nativeContext); 220 | } else if (Platform.isAndroid) { 221 | nativeContext = JAVAContext(); 222 | JAVAContextBuilder(nativeContext); 223 | } 224 | return executeNativeContext(nativeContext); 225 | } 226 | ``` 227 | 228 | So you can write the native call of two platforms quickly: 229 | 230 | ``` 231 | platformVersion = await Dna.traversingNative((ObjCContext context) { 232 | NativeObject version = context.classFromString('UIDevice').invoke(method: 'currentDevice').invoke(method: 'systemVersion'); 233 | version = context.classFromString("NSString").invoke(method: 'stringWithString:', args: ['iOS-']).invoke(method: 'stringByAppendingString:', args: [version]); 234 | 235 | context.returnVar = version; // Can be omitted 236 | }, (JAVAContext context) { 237 | NativeObject versionId = context.newJavaObjectFromConstructor('com.example.dna_example.DnaTest', null).invoke(method: 'getDnaVersion').invoke(method: 'getVersion'); 238 | NativeObject version = context.newJavaObjectFromConstructor('java.lang.String', ["android "]).invoke(method: "concat", args: [versionId]); 239 | 240 | context.returnVar = version; // Can be omitted 241 | }); 242 | ``` 243 | 244 | ## Principle introduction 245 | 246 | dna **does not involve the transformation from a dart object to a native object**, it also **does not care about the life cycle of the native object**, but **focuses on describing the `context` of native method calls**, When `context.execute()` called, a native method is called through `channel`, and the call stack is passed in the form of `JSON` for native dynamic parsing and calling. 247 | 248 | for example, Let's take a look at the previous Dart code: 249 | 250 | ``` 251 | ObjCContext context = ObjCContext(); 252 | NativeObject version = context.classFromString('UIDevice').invoke(method: 'currentDevice').invoke(method: 'systemVersion'); 253 | version = context.classFromString("NSString").invoke(method: 'stringWithString:', args: ['iOS-']).invoke(method: 'stringByAppendingString:', args: [version]); 254 | 255 | context.returnVar = version; // Can be omitted, See: Quick use of instantiated objects in JSON supported 256 | 257 | // Get native execution results directly 258 | var versionString = await context.execute(); 259 | ``` 260 | 261 | What the `execute()` method of `NativeContext` actually called is the following method: 262 | 263 | ``` 264 | static Future executeNativeContext(NativeContext context) async { 265 | return await _channel.invokeMethod('executeNativeContext', context.toJSON()); 266 | } 267 | ``` 268 | 269 | In the native executed method corresponding to the `executeNativeContext` method, the received 'JSON' is as follows: 270 | 271 | ``` 272 | { 273 | "_objectJSONWrappers": [], 274 | "returnVar": { 275 | "_objectId": "_objectId_WyWRIsLl" 276 | }, 277 | "_invocationNodes": [{ 278 | "returnVar": { 279 | "_objectId": "_objectId_KNWtiPuM" 280 | }, 281 | "object": { 282 | "_objectId": "_objectId_qyfACNGb", 283 | "clsName": "UIDevice" 284 | }, 285 | "method": "currentDevice" 286 | }, { 287 | "returnVar": { 288 | "_objectId": "_objectId_haPktBlL" 289 | }, 290 | "object": { 291 | "_objectId": "_objectId_KNWtiPuM" 292 | }, 293 | "method": "systemVersion" 294 | }, { 295 | "object": { 296 | "_objectId": "_objectId_UAUcgnOD", 297 | "clsName": "NSString" 298 | }, 299 | "method": "stringWithString:", 300 | "args": ["iOS-"], 301 | "returnVar": { 302 | "_objectId": "_objectId_UiCMaHAN" 303 | } 304 | }, { 305 | "object": { 306 | "_objectId": "_objectId_UiCMaHAN" 307 | }, 308 | "method": "stringByAppendingString:", 309 | "args": [{ 310 | "_objectId": "_objectId_haPktBlL" 311 | }], 312 | "returnVar": { 313 | "_objectId": "_objectId_WyWRIsLl" 314 | } 315 | }] 316 | } 317 | ``` 318 | 319 | Then we maintain an `objectsInContextMap` on the native side, its key is `objectId`, and the value is native object. 320 | 321 | `_invocationNodes` is the call context of the method, let's take a look at one of them. 322 | 323 | Here we will dynamically call `[UIDevice currentDevice]`, and return the object to `objectsInContextMap` with `_objectId_KNWtiPuM` stored in `returnVar` as the key. 324 | 325 | ``` 326 | { 327 | "returnVar": { 328 | "_objectId": "_objectId_KNWtiPuM" 329 | }, 330 | "object": { 331 | "_objectId": "_objectId_qyfACNGb", 332 | "clsName": "UIDevice" 333 | }, 334 | "method": "currentDevice" 335 | }, 336 | ``` 337 | 338 | Here, the object `_objectId_KNWtiPuM` is the returned value of the previous method. Take it out from the `objectsInContextMap`, continue the dynamic call, and store the new returned value with the `_objectId` of the `returnVar` as the key. 339 | 340 | ``` 341 | { 342 | "returnVar": { 343 | "_objectId": "_objectId_haPktBlL" 344 | }, 345 | "object": { 346 | "_objectId": "_objectId_KNWtiPuM" // Will find the real object in objectsInContextMap 347 | }, 348 | "method": "systemVersion" 349 | } 350 | ``` 351 | 352 | dna supports automatic package loading and unpacking when the method has parameters, such as `int<->NSNumber`, If the parameter is not one of the 15 basic types specified by `channel` but `NativeObject`, we will find the object from `objectsInContextMap` and put it into the actual parameter list. 353 | 354 | ``` 355 | { 356 | "object": { 357 | "_objectId": "_objectId_UiCMaHAN" 358 | }, 359 | "method": "stringByAppendingString:", 360 | "args": [{ 361 | "_objectId": "_objectId_haPktBlL" // Will find the real object in objectsInContextMap 362 | }], 363 | "returnVar": { 364 | "_objectId": "_objectId_WyWRIsLl" 365 | } 366 | ``` 367 | 368 | If final `returnVar` is set, The object corresponding to the `returnVar objectId` will be found from the `objectsInContextMap` and called back as the return value of the `channel `, if not, take the return value of the last `invocation`(if any). 369 | 370 | ## Author 371 | 372 | - yongguang.lyg@alibaba-inc.com 373 | - zhengguang.zzg@alibaba-inc.com 374 | - zyd178591@alibaba-inc.com 375 | 376 | ## Change log 377 | | version | note | 378 | | ------ | ------ | 379 | | 0.1.0 | alpha version | 380 | 381 | ## License 382 | 383 | dna is available under the MIT license.

85 | 86 | // 通过channel返回versionString 87 | ``` 88 | Dart 代码 89 | 90 | ``` 91 | ObjCContext context = ObjCContext(); 92 | NativeClass UIDevice = context.classFromString('UIDevice'); 93 | NativeObject device = UIDevice.invoke(method: 'currentDevice'); 94 | NativeObject version = device.invoke(method: 'systemVersion'); 95 | NativeObject platform = context.classFromString("NSString").invoke(method: 'stringWithString:', args: ['iOS-']); 96 | version = platform.invoke(method: 'stringByAppendingString:', args: [version]); 97 | 98 | context.returnVar = version; // 可省略设定最终返回值, 参考3 99 | 100 | // 直接获得原生执行结果 101 | var versionString = await context.execute(); 102 | ``` 103 | 104 | 105 | ### 2. 支持链式调用 106 | ObjC代码 107 | 108 | ``` 109 | NSString *versionString = [[UIDevice currentDevice] systemVersion]; 110 | versionString = [@"iOS-" stringByAppendingString: versionString]; 111 | 112 | // 通过channel返回versionString 113 | ``` 114 | 115 | Dart 代码 116 | 117 | ``` 118 | ObjCContext context = ObjCContext();

121 | 122 | context.returnVar = version; // 可省略设定最终返回值, 参考3 123 | 124 | // 直接获得原生执行结果 125 | var versionString = await context.execute(); 126 | ``` 127 | 128 | ### *关于Context的最终返回值 129 | 130 | `context.returnVar` 是 `context` 最终执行完毕返回值的标记 131 | 132 | 1. 设定context.returnVar: 返回该NativeObject对应的Native变量 133 | 2. 不设定context.returnVar: 执行到最后一个invoke，如果有返回值，作为context的最终返回值; 无返回值则返回空值; 134 | 135 | ``` 136 | ObjCContext context = ObjCContext(); 137 | context.classFromString('UIDevice').invoke(method: 'currentDevice').invoke(method: 'systemVersion'); 138 | 139 | // 直接获得原生执行结果 140 | var versionString = await context.execute(); 141 | ``` 142 | 143 | ### 3.支持快捷使用JSON中实例化对象 144 | 或许有些时候，我们需要用 `JSON` 直接实例化一个对象. 145 | 146 | ObjC代码 147 | 148 | ``` 149 | ClassA *objectA = [ClassA new]; 150 | objectA.a = 1; 151 | objectA.b = @"sss"; 152 | ``` 153 | 154 | 一般时候，这样写 155 | Dart 代码 156 | 157 | ``` 158 | ObjCContext context = ObjCContext(); 159 | NativeObject objectA = context.classFromString('ClassA').invoke(method: 'new'); 160 | objectA.invoke(method: 'setA:', args: [1]); 161 | objectA.invoke(method: 'setB:', args: ['sss']); 162 | ``` 163 | 也可以从JSON中生成 164 | 165 | ``` 166 | ObjCContext context = ObjCContext(); 167 | NativeObject objectA = context.newNativeObjectFromJSON({'a':1,'b':'sss'}, 'ClassA'); 168 | ``` 169 | 170 | ## Dart 调用 JAVA 171 | `JAVAContext` 仅在安卓系统中会被实际执行. `JAVAContext` 拥有上述 `ObjCContext` `Dart调ObjC` 的全部特性. 172 | 173 | * 支持上下文调用 174 | * 支持链式调用 175 | * 支持用JSON中实例化对象 176 | 177 | 另外，额外支持了从构造器中实例化一个对象 178 | 179 | ### 4. 支持快捷使用构造器实例化对象 180 | JAVA代码 181 | 182 | ``` 183 | String platform = new String("android"); 184 | ``` 185 | 186 | Dart 代码 187 | 188 | ``` 189 | NativeObject version = context 190 | .newJavaObjectFromConstructor('java.lang.String', ["android "]) 191 | 192 | ``` 193 | 194 | 195 | ## 快捷组织双端代码 196 | 提供了一个快捷的方法来 初始化和执行 context. 197 | 198 | ``` 199 | static Future traversingNative(ObjCContextBuilder(ObjCContext objcContext), JAVAContextBuilder(JAVAContext javaContext)) async { 200 | NativeContext nativeContext; 201 | if (Platform.isIOS) { 202 | nativeContext = ObjCContext(); 203 | ObjCContextBuilder(nativeContext); 204 | } else if (Platform.isAndroid) { 205 | nativeContext = JAVAContext(); 206 | JAVAContextBuilder(nativeContext); 207 | } 208 | return executeNativeContext(nativeContext); 209 | } 210 | 211 | ``` 212 | 可以快速书写两端的原生调用 213 | 214 | ``` 215 | platformVersion = await Dna.traversingNative((ObjCContext context) { 216 | NativeObject version = context.classFromString('UIDevice').invoke(method: 'currentDevice').invoke(method: 'systemVersion'); 217 | version = context.classFromString("NSString").invoke(method: 'stringWithString:', args: ['iOS-']).invoke(method: 'stringByAppendingString:', args: [version]); 218 | 219 | context.returnVar = version; // 该句可省略 220 | }, (JAVAContext context) { 221 | NativeObject versionId = context.newJavaObjectFromConstructor('com.example.dna_example.DnaTest', null).invoke(method: 'getDnaVersion').invoke(method: 'getVersion'); 222 | NativeObject version = context.newJavaObjectFromConstructor('java.lang.String', ["android "]).invoke(method: "concat", args: [versionId]); 223 | 224 | context.returnVar = version; // 该句可省略 225 | }); 226 | ``` 227 | 228 | # 原理简介 229 | `dna` 并不涉及` dart对象到Native对象的转换` ，也不关心 `Native对象的生命周期`，而是着重与描述原生方法调用的上下文，在 `context execute` 时通过 `channel` 调用一次原生方法，把调用栈以 `JSON` 的形式传过去供原生动态解析调用。 230 | 231 | 如前文的中 dart 代码 232 | 233 | ``` 234 | ObjCContext context = ObjCContext(); 235 | NativeObject version = context.classFromString('UIDevice').invoke(method: 'currentDevice').invoke(method: 'systemVersion'); 236 | version = context.classFromString("NSString").invoke(method: 'stringWithString:', args: ['iOS-']).invoke(method: 'stringByAppendingString:', args: [version]); 237 | 238 | context.returnVar = version; // 可省略设定最终返回值, 参考3 239 | 240 | // 直接获得原生执行结果 241 | var versionString = await context.execute(); 242 | ``` 243 | `NativeContext的execute()` 方法，实际调用了 244 | 245 | ``` 246 | static Future executeNativeContext(NativeContext context) async { 247 | return await _channel.invokeMethod('executeNativeContext', context.toJSON()); 248 | } 249 | ``` 250 | 251 | 在 `原生的 executeNativeContext` 对应执行的方法中，接收到的 `JSON` 是这样的 252 | 253 | ``` 254 | { 255 | "_objectJSONWrappers": [], 256 | "returnVar": { 257 | "_objectId": "_objectId_WyWRIsLl" 258 | }, 259 | "_invocationNodes": [{ 260 | "returnVar": { 261 | "_objectId": "_objectId_KNWtiPuM" 262 | }, 263 | "object": { 264 | "_objectId": "_objectId_qyfACNGb", 265 | "clsName": "UIDevice" 266 | }, 267 | "method": "currentDevice" 268 | }, { 269 | "returnVar": { 270 | "_objectId": "_objectId_haPktBlL" 271 | }, 272 | "object": { 273 | "_objectId": "_objectId_KNWtiPuM" 274 | }, 275 | "method": "systemVersion" 276 | }, { 277 | "object": { 278 | "_objectId": "_objectId_UAUcgnOD", 279 | "clsName": "NSString" 280 | }, 281 | "method": "stringWithString:", 282 | "args": ["iOS-"], 283 | "returnVar": { 284 | "_objectId": "_objectId_UiCMaHAN" 285 | } 286 | }, { 287 | "object": { 288 | "_objectId": "_objectId_UiCMaHAN" 289 | }, 290 | "method": "stringByAppendingString:", 291 | "args": [{ 292 | "_objectId": "_objectId_haPktBlL" 293 | }], 294 | "returnVar": { 295 | "_objectId": "_objectId_WyWRIsLl" 296 | } 297 | }] 298 | } 299 | ``` 300 | 我们在 `Native` 维护了一个 `objectsInContextMap` , `以objectId` 为键，以 `Native对象` 为值。 301 | 302 | `_invocationNodes` 便是方法的调用上下文, 看单个 303 | 304 | 这里会动态调用 `[UIDevice currentDevice]`, 返回对象以 `returnVar中存储的"_objectId_KNWtiPuM" ` 为键放到 `objectsInContextMap` 里 305 | 306 | ``` 307 | { 308 | "returnVar": { 309 | "_objectId": "_objectId_KNWtiPuM" 310 | }, 311 | "object": { 312 | "_objectId": "_objectId_qyfACNGb", 313 | "clsName": "UIDevice" 314 | }, 315 | "method": "currentDevice" 316 | }, 317 | ``` 318 | 319 | 这里 `调用方法的对象的objectId` 是 `"_objectId_KNWtiPuM"` ，是上一个方法的返回值，从`objectsInContextMap` 中取出，继续动态调用，以 `returnVar的object_id为键` 存储新的返回值。 320 | 321 | ``` 322 | { 323 | "returnVar": { 324 | "_objectId": "_objectId_haPktBlL" 325 | }, 326 | "object": { 327 | "_objectId": "_objectId_KNWtiPuM" // 会在objectsInContextMap找到中真正的对象 328 | }, 329 | "method": "systemVersion" 330 | } 331 | ``` 332 | 方法有参数时，支持自动装包和解包的，如 `int<->NSNumber..`, 如果参数是非 `channel` 规定的15种基本类型，是`NativeObject`, 我们会把对象从 `objectsInContextMap ` 中找出，放到实际的参数列表里 333 | 334 | ``` 335 | { 336 | "object": { 337 | "_objectId": "_objectId_UiCMaHAN" 338 | }, 339 | "method": "stringByAppendingString:", 340 | "args": [{ 341 | "_objectId": "_objectId_haPktBlL" // 会在objectsInContextMap找到中真正的对象 342 | }], 343 | "returnVar": { 344 | "_objectId": "_objectId_WyWRIsLl" 345 | } 346 | ``` 347 | ... 348 | 349 | 如果设置了`最终的returnVar`, 将把该 `returnVar objectId` 对应的对象从 `objectsInContextMap` 中找出来，作为 `channel的返回值` 回调回去。如果没有设置，取最后一个 `invocation` 的返回值(如果有)。 350 | 351 | ## 作者 352 | zyd178591@alibaba-inc.com, zhengguang.zzg@alibaba-inc.com, yongguang.lyg@alibaba-inc.com 353 | 354 | ## 更新日志 355 | | version | note | 356 | | ------ | ------ | 357 | | 0.1.0 | 能用 | 358 | 359 | ## License 360 | 361 | dna is available under the MIT license.
