【问题描述】：

我最近升级到 macOS Big Sur，然后开始出现此错误。

[PROJECT_NAME] flutter pub get
Running "flutter pub get" in PROJECT_NAME...             
Unhandled exception:

Bad state: Future already completed

我的 Flutter 医生是：

[✓] Flutter (Channel stable, 1.22.6, on macOS 11.2.1 20D75 darwin-x64, locale en-AU)
 
[✓] android toolchain - develop for Android devices (Android SDK version 30.0.2)
 
[✓] Xcode - develop for ios and macOS (Xcode 12.4)
[!] Android Studio (version 4.1)
    ✗ Flutter plugin not installed; this adds Flutter specific functionality.
    ✗ Dart plugin not installed; this adds Dart specific functionality.
[✓] VS Code (version 1.53.2)
[✓] Connected device (1 available)

! Doctor found issues in 1 category.

运行此命令后没有效果：

flutter config --no-analytics

我还卸载了防病毒软件以检查它是否被阻止，并确认没有防火墙阻止 Flutter 请求。

我已经检查了这些，但没有成功。

有人遇到类似问题吗？

【问题讨论】：

我也遇到了同样的问题，有什么解决办法吗？

@TapasPal，我同意这很烦人。为此，我不得不切换到另一台 Mac。尽管如此，Flutter 在我的旧 Mac 中仍然无法使用。 :(

【参考方案1】：

颤振升级-v

之后，测试一下：
