112 | ///获取overLayState 113 | SchedulerBinding.instance.addPostFrameCallback((t) => 114 | overlayState =globalKey.currentState.overlay 115 | ); 116 | ///指定MaterialApp的navigatorKey 117 | navigatorKey: globalKey, 118 | 119 | ``` 120 | 121 | * 在build属性中包裹组件 122 | 123 | ![image.png](https://p3-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/5770b6ef7ede429c95176e1eceb858b6~tplv-k3u1fbpfcp-watermark.image) 124 | 125 | ```dart 126 | builder: (ctx, child) => 127 | CustomWidgetInspector( 128 | child: child, 129 | ), 130 | ``` 131 | 132 | ### 3、如何使用 133 | 在完成了上述步骤之后，你只需要启动app，**该工具只会在profile/debug模式下集成**，在你的右下角会出现一个 ⏯ 按钮，点击开始记录，再次点击显示数据。 134 | 135 | ![Screenrecording_20210405_171133.gif](https://p1-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/4b13856e7c274513ac488f2959877786~tplv-k3u1fbpfcp-watermark.image) 136 | 137 | 如果想要结束采集，点击面板中的停止监听即可。 138 | 139 | 如果你想采集更多的帧，可以通过`kFpsInfoMaxSize`设置 140 | 141 | ![Screenrecording_20210405_171154.gif](https://p3-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/373a7a22b17d4b308eacaaaa933a3358~tplv-k3u1fbpfcp-watermark.image) 142 | 143 | ### 4、Warning： 144 | 145 | 空安全之前 请使用 1.12.13-2 分支 146 | 空安全后 使用 2.0.0 分支 147 | 148 | *** 149 | 150 | ### 四、how do it 来点原理？ 151 | 152 | 可能你会对这个工具的检测原理感兴趣，那咱们再来唠两句原理。 153 | 154 | #### 绘制数据的获取 155 | ```dart 156 | WidgetsBinding.instance.addTimingsCallback(monitor); 157 | ``` 158 | Flutter 会在每帧完成绘制后，会将耗时进行回调。耗时体现在三个变量上：1、构建时间；2、绘制时间；3、总时间。当你点击 ⏯ 按钮的时候，工具便开始采集耗时信息。 159 | 160 | 其实对于 Flutter 相关的渲染调度，推荐大家看看 `SchedulerBinding` ，里面写得再详细不过。 161 | 162 | #### 显示Fps界面 163 | 164 | 显示 Fps 的页面比较简单，直接通过 OverlayState 插入即可。如果你不太熟悉 Overlay 可以把它理解成浮窗。其中的表格绘制通过使用 DoKit 的自定义画笔实现，当然也可替换成各种开源的图表库。 165 | 166 | *** 167 | ## 最后 感谢各位吴彦祖和彭于晏的点赞,Start,和Follow 168 | 169 | 如果你觉得这个工具还不错，点个赞支持一下吧~ 170 | 171 | 最后附上我的： 172 | 173 | 掘金主页：[Nayuta]( https://juejin.cn/user/4309694831660711) 174 | 175 | 176 | 欢迎搜索公众号：**进击的Flutter或者runflutter** 里面整理收集了最详细的 Flutter 进阶与优化指南。关注我，获取我的最新文章~ 177 | 178 | 179 | ![1361617636891_.pic.jpg](https://p6-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/dd8c5b194fe244d7a8b56a68e254a4fb~tplv-k3u1fbpfcp-watermark.image) 180 | 181 | 182 | 如果使用过程有问题可以直接通过公众号私信我~ 183 | -------------------------------------------------------------------------------- /example/.gitignore: -------------------------------------------------------------------------------- 1 | # Miscellaneous 2 | *.class 3 | *.log 4 | *.pyc 5 | *.swp 6 | .DS_Store 7 | .atom/ 8 | .buildlog/ 9 | .history 10 | .svn/ 11 | 12 | # IntelliJ related 13 | *.iml 14 | *.ipr 15 | *.iws 16 | .idea/ 17 | 18 | # The .vscode folder contains launch configuration and tasks you configure in 19 | # VS Code which you may wish to be included in version control, so this line 20 | # is commented out by default. 21 | #.vscode/ 22 | 23 | # Flutter/Dart/Pub related 24 | **/doc/api/ 25 | .dart_tool/ 26 | .flutter-plugins 27 | .flutter-plugins-dependencies 28 | .packages 29 | .pub-cache/ 30 | .pub/ 31 | /build/ 32 | 33 | # Web related 34 | lib/generated_plugin_registrant.dart 35 | 36 | # Exceptions to above rules. 37 | !/packages/flutter_tools/test/data/dart_dependencies_test/**/.packages 38 | -------------------------------------------------------------------------------- /example/.metadata: -------------------------------------------------------------------------------- 1 | # This file tracks properties of this Flutter project. 2 | # Used by Flutter tool to assess capabilities and perform upgrades etc. 3 | # 4 | # This file should be version controlled and should not be manually edited. 5 | 6 | version: 7 | revision: f139b11009aeb8ed2a3a3aa8b0066e482709dde3 8 | channel: stable 9 | 10 | project_type: app 11 | -------------------------------------------------------------------------------- /example/README.md: -------------------------------------------------------------------------------- 1 | # example 2 | 3 | A new Flutter project. 4 | 5 | ## Getting Started 6 | 7 | This project is a starting point for a Flutter application. 8 | 9 | A few resources to get you started if this is your first Flutter project: 10 | 11 | - [Lab: Write your first Flutter app](https://flutter.dev/docs/get-started/codelab) 12 | - [Cookbook: Useful Flutter samples](https://flutter.dev/docs/cookbook) 13 | 14 | For help getting started with Flutter, view our 15 | [online documentation](https://flutter.dev/docs), which offers tutorials, 16 | samples, guidance on mobile development, and a full API reference. 17 | -------------------------------------------------------------------------------- /example/android/app/build.gradle: -------------------------------------------------------------------------------- 1 | def localProperties = new Properties() 2 | def localPropertiesFile = rootProject.file('local.properties') 3 | if (localPropertiesFile.exists()) { 4 | localPropertiesFile.withReader('UTF-8') { reader -> 5 | localProperties.load(reader) 6 | } 7 | } 8 | 9 | def flutterRoot = localProperties.getProperty('flutter.sdk') 10 | if (flutterRoot == null) { 11 | throw new GradleException("Flutter SDK not found.
