If page's Widget is a `StatefulWidget`, it will also be automatically checked Its corresponding `State`. 21 | 22 | ```dart 23 | import 'package:leak_detector/leak_detector.dart'; 24 | 25 | @override 26 | Widget build(BuildContext context) { 27 | return MaterialApp( 28 | navigatorObservers: [ 29 | //used the LeakNavigatorObserver 30 | LeakNavigatorObserver( 31 | shouldCheck: (route) { 32 | return route.settings.name != null && route.settings.name != '/'; 33 | }, 34 | ), 35 | ], 36 | ); 37 | } 38 | ``` 39 | 40 | #### Get leaked information 41 | 42 | `LeakDetector().onLeakedStream` can register your listener, and notify the object's reference chain after detecting a memory leak. 43 | `LeakDetector().onEventStream` can monitor internal time notifications, such as `start Gc`, `end Gc`, etc. 44 | 45 | A preview page of the reference chain is provided. You only need to add the following code. Note that the `Bulid Context` must be able to obtain the`NavigatorState`: 46 | 47 | ```dart 48 | import 'package:leak_detector/leak_detector.dart'; 49 | 50 | //show preview page 51 | LeakDetector().onLeakedStream.listen((LeakedInfo info) { 52 | //print to console 53 | info.retainingPath.forEach((node) => print(node)); 54 | //show preview page 55 | showLeakedInfoPage(navigatorKey.currentContext, info); 56 | }); 57 | ``` 58 | 59 | Preview page display: 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | It contains the class information of the reference chain node, the referenced attribute information, the source code of the attribute declaration, and the location of the source code (line number: column number). 68 | 69 | #### Get memory leak recording 70 | 71 | ```dart 72 | import 'package:leak_detector/leak_detector.dart'; 73 | 74 | getLeakedRecording().then((List infoList) { 75 | showLeakedInfoListPage(navigatorKey.currentContext, infoList); 76 | }); 77 | ``` 78 | 79 | 80 | 81 | 82 | #### *Cannot connect to `vm_service` on real mobile devices 83 | 84 | The VM service allows for an extended feature set via the Dart Development Service (DDS) that forward all core VM service RPCs described in this document to the true VM service. 85 | 86 | So when we connect to the computer to run, the `DDS` on the computer will first connect to the `vm_service` on our mobile end, causing our `leak_detector` plugin to fail to connect to the `vm_service` again. 87 | 88 | There are two solutions: 89 | 90 | - After the `run` is complete, disconnect from the computer, and then it is best to restart the app. 91 | 92 | If the completed test package is installed on the mobile phone, the above problem does not exist, so this method is suitable for use by testers. 93 | 94 | - Add the `--disable-dds` parameter after `flutter run` to turn off the `DDS`. After testing, this will not cause any impact on debugging 95 | 96 | It can be configured as follows in `Android Studio`. 97 | 98 | After [Pull Request #80900](https://github.com/flutter/flutter/pull/80900) is merged, `--disable-dds` was renamed to `--no-dds` 99 | 100 | 101 | ![image](https://liujiakuoyx.github.io/images/leak_detector/peizhi1.png) 102 | 103 | 104 | ![image](https://liujiakuoyx.github.io/images/leak_detector/peizhi2.png) -------------------------------------------------------------------------------- /README_zh-CN.md: -------------------------------------------------------------------------------- 1 | # leak_detector 2 | 3 | flutter内存泄漏检测工具 4 | 5 | ## 开始使用 6 | 7 | #### 初始化 8 | 9 | 为了避免底层库`vm_service`发生crash，请在添加内存泄漏检测对象之前调用： 10 | ```dart 11 | //maxRetainingPath:引用链的最大长度，设置越短性能越高，但是很有可能获取不到完整的泄漏路径 默认是 300 12 | LeakDetector().init(maxRetainingPath: 300); 13 | ``` 14 | 开启泄漏检测会降低性能，Full GC可能会使页面掉帧。 15 | 插件中通过`assert`语句初始化，所以您不用特意在`release`版本中关闭该插件。 16 | 17 | #### 检测 18 | 19 | 在`MaterialApp`增加路由的监听器`LeakNavigatorObserver`，这样将会自动检测页面的`Widget`和其对应的`Element`是否存在内存泄漏，如果页面的`Widget`是`StatefulWidget`，也会自动检查其对应的`State`对象。 20 | 21 | ```dart 22 | import 'package:leak_detector/leak_detector.dart'; 23 | 24 | @override 25 | Widget build(BuildContext context) { 26 | return MaterialApp( 27 | navigatorObservers: [ 28 | //used the LeakNavigatorObserver 29 | LeakNavigatorObserver( 30 | //返回false则不会校验这个页面. 31 | shouldCheck: (route) { 32 | return route.settings.name != null && route.settings.name != '/'; 33 | }, 34 | ), 35 | ], 36 | ); 37 | } 38 | ``` 39 | 40 | #### 获取泄漏信息 41 | 42 | `LeakDetector().onLeakedStream`可以注册自己的监听函数，在检测到内存泄漏之后会通知对象的引用链数据。 43 | `LeakDetector().onEventStream`可以监听内部时间的通知，如`startGc`，`endGc`等。 44 | 45 | 提供了一个引用链的预览页面，你只需要添加以下代码即可，注意其中的`BulidContext`必须能够获取`NavigatorState`： 46 | 47 | ```dart 48 | import 'package:leak_detector/leak_detector.dart'; 49 | 50 | //show preview page 51 | LeakDetector().onLeakedStream.listen((LeakedInfo info) { 52 | //print to console 53 | info.retainingPath.forEach((node) => print(node)); 54 | //show preview page 55 | showLeakedInfoPage(navigatorKey.currentContext, info); 56 | }); 57 | ``` 58 | 59 | 页面展示效果如下: 60 | 61 |
62 |          63 |
64 | 65 | 66 | 其中包含引用链节点的类信息、被引用属性信息、属性声明源码、源码位置（行号:列号）。 67 | 68 | #### 内存泄漏历史记录 69 | 70 | ```dart 71 | import 'package:leak_detector/leak_detector.dart'; 72 | 73 | getLeakedRecording().then((List infoList) { 74 | showLeakedInfoListPage(navigatorKey.currentContext, infoList); 75 | }); 76 | ``` 77 | 78 | 79 |
80 | 81 |
82 | 83 | 84 | #### *真机上无法连接vm_service问题 85 | 86 | `vm_service` 存在 [Single Client Mode](https://github.com/dart-lang/sdk/blob/master/runtime/vm/service/service.md#single-client-mode)(单一客户端模式)。 87 | 88 | 当`DDS(Dart Development Service)`连接到`vm_service`时，`vm_service`进入单一客户端模式，之后不再接受其他的`WebSocket`连接，而是将`WebSocket`转发给`DDS`，直到`DDS`与`vm_service`断开连接，则`vm_service`才能再次开始接受`WebSocket`请求。 89 | 90 | 所以当我们连接电脑运行的时候，电脑端的`DDS`会首先连接到我们的移动端的`vm_service`的`WebSocket`服务，导致我们的`leak_detector`插件无法再次连接到`vm_service`。 91 | 92 | 有两种解决办法： 93 | 94 | - `run`完成之后，断开与电脑端的连接，然后最好重启app。 95 | 96 | 如果是打好的测试包安装在手机上，是不存在上面的问题的，所以这种方法适用于给测试人员使用的情况下。 97 | 98 | - 在`flutter run`后面加上`--disable-dds`参数关闭调试端的`DDS`服务，经过测试，这样做并不会造成调试端的功能问题。 99 | 100 | 要是使用`Android Studio`也可以像下面这样配置。 101 | 102 | **注意**：在 [Pull Request #80900](https://github.com/flutter/flutter/pull/80900) 合入之后，`--disable-dds`被改名为`--no-dds` 103 | 104 | 105 | ![image](https://liujiakuoyx.github.io/images/leak_detector/peizhi1.png) 106 | 107 | 108 | ![image](https://liujiakuoyx.github.io/images/leak_detector/peizhi2.png) -------------------------------------------------------------------------------- /android/.gitignore: -------------------------------------------------------------------------------- 1 | *.iml 2 | .gradle 3 | /local.properties 4 | /.idea/workspace.xml 5 | /.idea/libraries 6 | .DS_Store 7 | /build 8 | /captures 9 | -------------------------------------------------------------------------------- /android/build.gradle: -------------------------------------------------------------------------------- 1 | group 'com.ljk.leak_detector' 2 | version '1.0-SNAPSHOT' 3 | 4 | buildscript { 5 | ext.kotlin_version = '1.7.10' 6 | repositories { 7 | google() 8 | jcenter() 9 | } 10 | 11 | dependencies { 12 | classpath 'com.android.tools.build:gradle:7.3.0' 13 | classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" 14 | } 15 | } 16 | 17 | rootProject.allprojects { 18 | repositories { 19 | google() 20 | jcenter() 21 | } 22 | } 23 | 24 | allprojects { 25 | gradle.projectsEvaluated { 26 | tasks.withType(JavaCompile) { 27 | options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation" 28 | } 29 | } 30 | } 31 | 32 | apply plugin: 'com.android.library' 33 | apply plugin: 'kotlin-android' 34 | 35 | android { 36 | compileSdkVersion 31 37 | 38 | sourceSets { 39 | main.java.srcDirs += 'src/main/kotlin' 40 | } 41 | defaultConfig { 42 | minSdkVersion 16 43 | } 44 | lintOptions { 45 | disable 'InvalidPackage' 46 | } 47 | } 48 | 49 | dependencies { 50 | implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" 51 | } 52 | -------------------------------------------------------------------------------- /android/gradle.properties: -------------------------------------------------------------------------------- 1 | org.gradle.jvmargs=-Xmx1536M 2 | android.useAndroidX=true 3 | android.enableJetifier=true 4 | -------------------------------------------------------------------------------- /android/gradle/wrapper/gradle-wrapper.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/liujiakuoyx/leak_detector/7c68ab8ca205e747e32e1d047036541daa238a78/android/gradle/wrapper/gradle-wrapper.jar -------------------------------------------------------------------------------- /android/gradle/wrapper/gradle-wrapper.properties: -------------------------------------------------------------------------------- 1 | distributionBase=GRADLE_USER_HOME 2 | distributionPath=wrapper/dists 3 | distributionUrl=https\://services.gradle.org/distributions/gradle-7.4-bin.zip 4 | zipStoreBase=GRADLE_USER_HOME 5 | zipStorePath=wrapper/dists 6 | -------------------------------------------------------------------------------- /android/gradlew: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | # 4 | # Copyright © 2015-2021 the original authors. 5 | # 6 | # Licensed under the Apache License, Version 2.0 (the "License"); 7 | # you may not use this file except in compliance with the License. 8 | # You may obtain a copy of the License at 9 | # 10 | # https://www.apache.org/licenses/LICENSE-2.0 11 | # 12 | # Unless required by applicable law or agreed to in writing, software 13 | # distributed under the License is distributed on an "AS IS" BASIS, 14 | # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 15 | # See the License for the specific language governing permissions and 16 | # limitations under the License. 17 | # 18 | 19 | ############################################################################## 20 | # 21 | # Gradle start up script for POSIX generated by Gradle. 22 | # 23 | # Important for running: 24 | # 25 | # (1) You need a POSIX-compliant shell to run this script.
