旧的颤振项目只是以荒谬的方式中断

https://github.com/flutter/flutter/issues/16441

有一种方法可以修复它，因为我在我的项目中修复了它

https://github.com/hungrymonkey/mic_stream/issues/2

步骤： 1. 更新所有插件和flutter环境到stable 1.0 在您的 pubspec.yaml 添加

environment:
  sdk: ">=2.0.0-dev.68.0 <3.0.0" 

1. 将您的 android studio 更新到最新的稳定版

2. 按照 mran-google https://github.com/flutter/flutter/issues/16215#issuecomment-378502866 的建议打开 your_project/android/ 文件夹

3. 运行构建并进行所有小修复

4. 在your_project/android/build.gradle 中，类路径等级版本应更改为3.2.1 https://github.com/flutter/flutter/pull/17942/files
5. 在your_project/android/gradle/wrapper/gradle-wrapper.properties 中，将distributionUrl 从https\://services.gradle.org/distributions/gradle-3.x-all.zip 更改为https\://services.gradle.org/distributions/gradle-4.6-all.zip
6. 修复所有 Dart 1 到 2 转换错误

我相信这些都是在 Flutter 上迁移旧项目所需的所有更改。
