每当我尝试运行应用程序时，都会收到这个错误。我尝试了从升级flutter到添加dependency_overrides的所有方法，但都没有成功。

我注意到，尽管我进行了更新，但我的pubspec.yaml文件中的sdk版本仍然保持不变。根据其他解决方案，它应该是">2.16.0<3.0.0英寸开始工作。
environment:
sdk: ">=2.15.0 <3.0.0"
如果我尝试手动更改它，它会抛出这个错误
The current Dart SDK version is 2.15.0.
Because purple requires SDK version >=2.16.0 <3.0.0, version solving failed.
pub get failed (1; Because purple requires SDK version >=2.16.0 <3.0.0, version solving failed.)
这是我输入flutter --version后得到的输出
