简介
一旦将flutter模块集成到原生项目中，由其是iOS的原生项目，我们是否能够保留flutter的快速开发调试的优势呢？ 即是否还可以通过Hot reload 或者 Hot Restart来快速开发呢？ 那么对应flutter模块，我们如何使用hot reload加速我们的调试速度呢？
答案就是：flutter attach 调试 （开发工具：Xcode 、Visual Studio Code 、Android Studio ）
一：Visual Studio Code
1、 Xcode 启动原生项目 （此处flutter模块已嵌入原生, 2、创建launch.json 文件 如下图
3、VSCode 编辑 launch.json -> 追加如下代码：
{
"name": "Flutter: Attach to Device",
"type": "dart",
"request": "attach"
}
4、如下图选中刚刚配置的 "request": "attach" 点击 Run
5、完成配置 现在可在iOS 断点Xcode 中调试，Flutter VSCode 中断点调试
二：Android Studio
1、Xcode 启动原生项目 （此处flutter模块已嵌入原生,
2、Android Studio 中打开终端输入 flutter attach 命令（展示可用模拟器列表，仅有一个则跳过此步）
bogon:test_flutter zhanghua$ flutter attach

Please choose one (To quit, press "q/Q"): q
bogon:test_flutter zhanghua$
3、执行 flutter attach -d <设备ID> 命令选择要启动的模拟器 (无下面报错，跳过此步)
bogon:test_flutter zhanghua$ flutter attach -d AD044D50-3DCC-495A-9D96-981349214F67
There are multiple observatory ports available.
Rerun this command with one of the following passed in as the appId:
flutter attach -- app-id com.example.myFlutter
flutter attach -- app-id com.test.flutter
bogon:test_flutter zhanghua$
4、执行 flutter attach -- app-id com.test.flutter -d AD044D50-3DCC-495A-9D96-981349214F67 命令
bogon:test_flutter zhanghua$ flutter attach -- app-id com.test.flutter -d AD044D50-3DCC-495A-9D96-981349214F67
