Flutter 项目异常

一、Flutter 导包错误 Target of URI doesn‘t exist

在Android studio 导入Flutter 项目一片红色，全部提示 Target of URI doesn’t exist

配置镜像：https://flutter.cn/community/china#configuring-flutter-to-use-a-mirror-site

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

Run 'flutter pub get' 依然出现如下提示：

"D:\Program Files\flutter\bin\flutter.bat" --no-color pub get
Waiting for another flutter command to release the startup lock...
 

删除\flutter\bin\cache\lockfile文件（要关闭sutdio 和 任务管理中所有dart进程），重启studio  Run 'flutter pub get' 完美解决

二、Because flutter_app depends on flutter_test any from sdk which doesn't exist (the Flutter SDK is not available), version solving failed.

解决，输入flutter package get：

若还不能解决 查看file-setting-languages&Frameworks

Dart   ：.勾选 “enable Dart support for the project”，并且选择Dart SDK path，路径为 D:\install\android\flutter\bin\cache\dart-sdk ，

Flutter：D:\install\android\flutter是flutter SDK路径
