我有一个错误:
Running "flutter packages upgrade" in bingo360...
The current Dart SDK version is 2.1.2-dev.0.0.flutter-0a7dcf17eb.
Because bingo360 depends on flutter_launcher_icons >=0.7.1 which requires SDK version >=2.2.0 <3.0.0, version solving failed.
pub upgrade failed (1)
我的pubspec.yaml是:
environment:
sdk: ">=2.1.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.2
http: ^0.12.0+1
flutter_launcher_icons: "^0.7.2"
dev_dependencies:
flutter_test:
sdk: flutter
我试着换成sdk: ">2.2.0 <3.0.0"，但没用.
有什么建议吗？
