When you’re using someone else’s API or when you implement a library that’s widely used, it’s often impractical or impossible to change the API. But you might still want to add some functionality. 9 | 10 | *let me know if you want something specific or you found a bug at bar.idan@gmail.com* 11 | ## Let get started 💪🏻 12 | 13 | 1. Go to `pubspec.yaml` 14 | 2. add a dart_extensions and replace `[version]` with the latest version: 15 | 16 | ```dart 17 | dependencies: 18 | dart_extensions: ^[version] 19 | ``` 20 | 21 | 3. click the packages get button or *flutter pub get* 22 | ## Responsive UI 23 | Very common way to calculate size in percentage is using the MediaQuery like so: 24 | ```dart 25 | MediaQuery.of(context).size.width * 0.1 26 | ``` 27 | 28 | 29 | Flatten a nested Map into a single level map 30 | ```dart 31 | response.flatJson({ 32 | 'key1': {'keyA': 'valueI'}, 33 | 'key2': {'keyB': 'valueII'}, 34 | 'key3': { 35 | 'a': { 36 | 'b': {'c': 2} 37 | } 38 | } 39 | }); 40 | 41 | The result you can also specify max depth, its the maximum number of nested objects to flatten. 42 | ``` 43 | // { 44 | // 'key1.keyA': 'valueI', 45 | // 'key2.keyB': 'valueII', 46 | // 'key3.a.b.c': 2 47 | // }; 48 | 49 | 50 | Instead of the boilerplate we can use this awesome extension and get the same results. 51 | 52 | Wrap your Application with: 53 | ```dart 54 | ResponsiveApp( 55 | builder: (BuildContext context, Orientation orientation, DeviceType deviceType) { 56 | return YourAppWidget() 57 | ) 58 | ``` 59 | 60 | ```dart 61 | AnimatedList( 62 | key: chatListKey, 63 | reverse: true, 64 | padding: EdgeInsets.only(top: 10.textSizeResponsive), 65 | shrinkWrap: true, 66 | ``` 67 | Also the text should be responsive, no problem 68 | ```dart 69 | Text( 70 | 'Note added by ${message.from ?? ''}', 71 | style: avanirBook.copyWith(fontSize: 8.responsiveText), 72 | ), 73 | ``` 74 | 75 | ## Iterable Extensions 76 | 77 | ### .any() 78 | Returns `true` if at least one element matches the given predicate. 79 | ```dart 80 | final users = [User(22, "Kasey"), User(23, "Jadn")]; 81 | users.any((u) => u.name == 'Kasey') // true 82 | ``` 83 | 84 | ### .groupBy() 85 | Groups the elements in values by the value returned by key. 86 | ```dart 87 | final users = [User(22, "Kasey"), User(23, "Jadn"), User(22, "Rene"), User(32, "Aden")]; 88 | 89 | users.groupBy((u) => u.age); 90 | ``` 91 | Sort the users by age: 92 | ```dart 93 | { 94 | 22: [User:22, Kasey, User:22, Rene], 95 | 23: [User:23, Jadn], 96 | 32: [User:32, Aden] 97 | } 98 | ``` 99 | 100 | ### .sortBy() 101 | Sorts elements in the array in-place according to natural sort order of the value returned by specified selector function. 102 | ```dart 103 | final users = [User(22, "Kasey"), User(16, "Roni"), User(23, "Jadn")]; 104 | users.sortBy((u) => u.age) /// [User(16, "Roni"), [User(22, "Kasey"), User(23, "Jadn")] 105 | ``` 106 | 107 | ### .find() 108 | Returns the first element matching the given predicate, or `null` if element wasn't found. 109 | ```dart 110 | final users = [User(22, "Kasey"), User(23, "Jadn"), User(22, "Rene"), User(32, "Aden")]; 111 | 112 | users.find((u) => u.name == "Rene") // User(22, "Rene") 113 | ``` 114 | 115 | ### .chunks() 116 | Splits the Iterable into chunks of the specified `size` 117 | ```dart 118 | [1, 2, 3, 4, 5, 6, 7, 8, 9, 10].chunks(3)) 119 | ``` 120 | *result* 121 | ```dart 122 | ([1, 2, 3], [4, 5, 6], [7, 8, 9], [10]) 123 | ``` 124 | 125 | ### .filter() 126 | Returns a list containing only elements matching the given predicate, the return type will be `List`, 127 | unlike the `where` operator that return `Iterator`, also it filters null. 128 | ```dart 129 | final users = [User(22, "Kasey"), User(23, "Jadn"), User(22, "Rene"), User(32, "Aden")]; 130 | final filtered = users.filter((u) => u.name == "Kasey"); // [User(22, "Kasey")] <- Type List 131 | 132 | final listWithNull = [null, User(23, "Jadn"), User(22, "Rene"), User(32, "Aden")]; 133 | final filtered = listWithNull.filter((u) => u.name == "Jadn"); // [User(23, "Jadn")] 134 | ``` 135 | 136 | ### .intersect() 137 | Returns a set containing all elements that are contained by both this set and the specified collection. 138 | ```dart 139 | Set.from([1, 2, 3, 4]).intersect(Set.from([3, 4, 5, 6]) // 1,2,3,4,5,6 140 | ``` 141 | 142 | ### .filterNot() 143 | Returns a list containing only not the elements matching the given predicate, the return type will be `List`, 144 | unlike the `where` operator that return `Iterator`, also it filters null. 145 | ```dart 146 | final users = [User(22, "Kasey"), User(23, "Jadn"), User(22, "Rene"), User(32, "Aden")]; 147 | final filtered = users.filterNot((u) => u.name == "Kasey"); // [User(23, "Jadn"), User(22, "Rene"), User(32, "Aden")] <- Type List 148 | 149 | final listWithNull = [null, User(23, "Jadn"), User(22, "Rene"), User(32, "Aden")]; 150 | final filtered = listWithNull.filterNot((u) => u.name == "Jadn"); // [User(22, "Rene"), User(32, "Aden")] 151 | ``` 152 | 153 | ### .takeOnly() 154 | Returns a list containing first [n] elements. 155 | ```dart 156 | [1, 2, 3, 4].takeOnly(1) // [1] 157 | ``` 158 | 159 | ### .drop() 160 | Returns a list containing all elements except first [n] elements. 161 | ```dart 162 | [1, 2, 3, 4].drop(1) // [2, 3, 4] 163 | ``` 164 | 165 | ### .forEachIndexed() 166 | Performs the given action on each element on iterable, providing sequential `index` with the `element`. 167 | ```dart 168 | ["red","green","blue"].forEachIndexed((item, index) { 169 | print("$item, $index"); 170 | }); // 0: red // 1: green // 2: blue``` 171 | ``` 172 | 173 | ### .sortedDescending() 174 | Returns a new list with all elements sorted according to descending natural sort order. 175 | ```dart 176 | var list = [1,2,3,4,5]; 177 | final descendingList = list.sortedDescending(); 178 | print(descendingList); // [5, 4, 3, 2, 1] 179 | ``` 180 | 181 | ### .count() 182 | Return a number of the existing elements by a specific predicate 183 | ```dart 184 | final users = [User(33, "Miki"), User(45, "Anna"), User(19, "Amit")]; 185 | 186 | final aboveAgeTwenty = users.count((user) => user.age > 20); 187 | print(aboveAgeTwenty); // 2 188 | ``` 189 | 190 | ### .associate() 191 | Creates a Map instance in which the keys and values are computed from the iterable. 192 | ```dart 193 | final users = [User(33, "Miki"), User(45, "Anna"), User(19, "Amit")]; 194 | 195 | users.associate((k) => k.name, (e) => e.age) // 'Miki': 33, 'Anna': 45, 'Amit': 19} 196 | ``` 197 | 198 | ### .concatWithMultipleList() 199 | Return a list concatenates the output of the current list and multiple iterables. 200 | ```dart 201 | final listOfLists = [ 202 | [5, 6, 7], 203 | [8, 9, 10] 204 | ]; 205 | [1, 2, 3, 4].concatWithMultipleList(listOfLists); 206 | 207 | // [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] 208 | ``` 209 | 210 | ### .distinctBy() 211 | Returns a list containing only the elements from given collection having distinct keys. 212 | ```dart 213 | // example 1 214 | final users = ["Zack", "Ian", "Ronit"]; 215 | users.distinctBy((u) => u.toLowerCase().startsWith("z")); // Zack 216 | 217 | // example 2 218 | final users = [User(11, 'idan'), User(12, 'ronit'), User(11, 'asaf')]; 219 | 220 | final dist = users.distinctBy((u) => u.age); 221 | dist.forEach((u) => print(u.age)); // 11, 12 222 | ``` 223 | 224 | ### .zip() 225 | Zip is used to combine multiple iterables into a single list that contains the combination of them two. 226 | ```dart 227 | 228 | final soldThisMonth = [Motorcycle(2020, 'BMW R1200GS'), Motorcycle(1967, 'Honda GoldWing')]; 229 | final soldLastMonth = [Motorcycle(2014, 'Honda Transalp'), Motorcycle(2019, 'Ducati Multistrada')]; 230 | 231 | final sales = soldThisMonth.zip(soldLastMonth).toList(); 232 | 233 | print(sales); // [ 234 | [brand: BMW R1200GS year: 2020, brand: Honda Transalp year: 2014], // first pair from this month and last 235 | [brand: Honda GoldWing year: 1967, brand: Ducati Multistrada year: 2019] // second pair from last month 236 | ] 237 | ``` 238 | See [iterable.dart](https://github.com/droididan/dart_extentions/blob/master/lib/iterable.dart) for more examples. 239 | 240 | ## Flutter Extensions 241 | 242 | ### Context extensions 243 | Are you not tired from typing `MediaQuery.of(context).size...` to get height or width? here's a cool extension 244 | ```dart 245 | context.mq // returns the MediaQuery 246 | ``` 247 | 248 | ```dart 249 | context isLandscape // returns if Orientation is landscape 250 | ``` 251 | 252 | ```dart 253 | context.sizePx // returns same as MediaQuery.of(context).size 254 | ``` 255 | 256 | ```dart 257 | context.widthPx // returns same as MediaQuery.of(context).size.width 258 | ``` 259 | 260 | ```dart 261 | context.heightPx // returns same as MediaQuery.of(context).height 262 | ``` 263 | 264 | ### Text Extensions 265 | ```dart 266 | final text = Text('hello') 267 | .bold() 268 | .fontSize(25) 269 | .italic();

287 | } 288 | 289 | class _HomeState extends State { 290 | 291 | @override 292 | Widget build(BuildContext context) { 293 | return Scaffold( 294 | body: Container( 295 | child: Stack( 296 | children: [ 297 | Container( 298 | height: 100, 299 | width: 100, 300 | ) .withRoundCorners(backgroundColor: Colors.grey) 301 | .withShadow() 302 | .alignAtCenter() 303 | .toCenter() 304 | .withTooltip('just a tooltip') 305 | .paddingOnly(left: 10) 306 | .paddingAll(20) 307 | .onTap(() => print('tap')) 308 | .onLongPress(() => print('long press')) 309 | ], 310 | ), 311 | ), 312 | ); 313 | } 314 | } 315 | ``` 316 | 317 | ### Navigation 318 | We can navigate from every widget by calling these methods 319 | ```dart 320 | navigateTo(route: MaterialPageRoute(builder: (c) => Login())); 321 | navigateByRouteName(Routes.home, ); 322 | final result = navigateBack(); 323 | ``` 324 | 325 | 326 | ## Http Extensions 327 | 328 | ### .httpGet() 329 | Sends an HTTP GET request with the given headers to the given URL 330 | ```dart 331 | final json = await "https://jsonplaceholder.typicode.com/posts".httpGet(); 332 | ``` 333 | *result:* 334 | ```json 335 | [ 336 | { 337 | "userId": 1, 338 | "id": 1, 339 | "title": "sunt aut facere", 340 | "body": "quia et suscipit" 341 | }, 342 | { 343 | "userId": 1, 344 | "id": 2, 345 | "title": "qui est esse", 346 | "body": "dolor beatae ea dolores neque" 347 | }, 348 | ] 349 | ``` 350 | 351 | *usage with then:* 352 | ```dart 353 | "https://jsonplaceholder.typicode.com/posts".httpGet().then((result) { 354 | print(result); 355 | }).catchError((e) => print(e)); 356 | ``` 357 | 358 | ### .httpPost() 359 | Sends an HTTP POST request with the given headers and body to the given URL which can be a [Uri] or a [String]. 360 | ```dart 361 | String json = '{"title": "Hello", "body": "body text", "userId": 1}'; 362 | final json = await "https://jsonplaceholder.typicode.com/posts".httpPost(json); 363 | ``` 364 | 365 | for more examples (put, delete) See [http.dart](https://github.com/droididan/dart_extentions/blob/master/lib/http.dart) 366 | 367 | ## Range Extensions 368 | ### .until() 369 | Returns a sequence of integer, starting from the current number until the [end] number. [step] is optional, it will step number if given 370 | ```dart 371 | for(final num in 1.until(10)) { 372 | numbers.add(num); 373 | } 374 | ``` 375 | *result* 376 | ```dart 377 | [1, 2, 3, 4, 5, 6, 7, 8, 9] 378 | ``` 379 | with step: 380 | ```dart 381 | for(final num in 1.until(10, step: 2)) { 382 | numbers.add(num); 383 | } 384 | ``` 385 | *result* 386 | ```dart 387 | [1, 3, 5, 7, 9] 388 | ``` 389 | 390 | ## String Extensions 391 | 392 | 393 | ### .asBool() 394 | Returns true if this string is any of these values: "true", "yes", "1", or if the string is a number and greater than 0, false if less than 1. This is also case insensitive. 395 | ```dart 396 | 'true'.asBool // true 397 | 'True'.asBool // true 398 | 'false'.asBool // false 399 | 'False'.asBool // false 400 | 'yes'.asBool // true 401 | 'YES'.asBool // true 402 | 'no'.asBool // false 403 | 'NO'.asBool // false 404 | ``` 405 | 406 | 407 | ### .insert() 408 | Returns a new string in which a specified string is inserted at a specified index position in this instance. 409 | ```dart 410 | 'test'.insert(1, 't') // 'ttest' 411 | '123456890'.insert(6, '7') // '1234567890' 412 | 'dart cool'.insert(4, ' is') // 'dart is cool' 413 | ``` 414 | 415 | ### .isNullOrWhiteSpace() 416 | Indicates whether a specified string is `null`, `empty`, or consists only of `white-space` characters. 417 | ```dart 418 | 'test'.isNullOrWhiteSpace // false 419 | ' '.isNullOrWhiteSpace, // true 420 | null.isNullOrWhiteSpace, // true 421 | ' te st '.isNullOrWhiteSpace // false 422 | ``` 423 | 424 | ### .replaceAfter() 425 | Replace part of string after the first occurrence of given delimiter. 426 | ```dart 427 | print("myemail@".replaceAfter("@", "gmail.com"));
