android - 错误: Member not found: 'packageRoot' ,如何解决忽略: deprecated_member_use in Flutter?

Question

在我的flutter项目中，我对插件做了一些更新，然后使用了flutter upgrade。之后，每当我运行我的 flutter 项目时，它都会显示以下错误-

    /C:/src/flutter/flutter/.pub-cache/hosted/pub.dartlang.org/platform-3.0.2/lib/src/interface/local_platform.dart:46:19: Error: Member not found: 'packageRoot'.
          io.Platform.packageRoot; // ignore: deprecated_member_use
                      ^^^^^^^^^^^ FAILURE: Build failed with an exception.

* Where: Script 'C:\src\flutter\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 1102

* What went wrong: Execution failed for task ':app:compileFlutterBuildDebug'.
> Process 'command 'C:\src\flutter\flutter\bin\flutter.bat'' finished with non-zero exit value 1

* Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

所以，我需要一个建议，我该如何解决这个问题？

你需要升级你的依赖来解决这个问题，所以运行:

flutter pub upgrade

如果这仍然不起作用，则意味着您遇到了来自 platform 的传递依赖的问题。 ( platform 低于 3.1.0 的版本有这个问题)。因此，覆盖 platform包装在您的 pubspec.yaml 中像这样的文件:

dependency_overrides:
  platform: ^3.1.0
