Flutter 需要 SDK 版本

Question

我有这个错误:

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

我试着改成sdk: ">2.2.0 <3.0.0"但不起作用。

有什么建议吗？

转到“工具”-> Flutter ->“Flutter 升级”

看看是否可行。如果是需要升级的SDK不能手动修改
