问题1:The log reader stopped unexpectedly

  1. 1.断开设备
  2. 2.清除设备的缓存数据（移动）的文件管理器应用程序
  3. 3.Run flutter clean
  4. 4.连接您的设备并运行应用程序

问题2:代码各种依赖报错

  1. 解决：
  2. flutter clean
  3. 看看是否可以了：flutter run 
  5. 还是出错：
  6. flutter pub cache repair
  8. 最后：flutter clean
  9. 当 flutter pub cache repair 过程报错时，就退出终端 执行flutter clean 再次执行flutter pub cache repair
  1. 我试过（从androidstudio）Tools > Flutter > Flutter Clean
  2. 和File > Invalidate Caches / Restart...，但都没用。

问题3:下载慢

  1. git clone -b stable https://github.com/flutter/flutter.git 比较缓慢解决方案如下

  4. export FLUTTER_STORAGE_BASE_URL=https://mirrors.sjtug.sjtu.edu.cn
  5. export PUB_HOSTED_URL=https://dart-pub.mirrors.sjtug.sjtu.edu.cn

问题4:Building flutter tool…慢

  1. flutter doctor时Building flutter tool...缓慢添加如下环境变量
  3. #export FLUTTER_STORAGE_BASE_URL=https://mirrors.sjtug.sjtu.edu.cn
  4. #export PUB_HOSTED_URL=https://dart-pub.mirrors.sjtug.sjtu.edu.cn
  5. export PUB_HOSTED_URL=https://pub.flutter-io.cn
  6. export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
