Android Studio - Flutter 插件未安装；这增加了 Flutter 特定的功能

考虑到我已经遵循了所有这些步骤https://flutter.dev/docs/get-started/install/linux https://flutter.dev/docs/get-started/install/linux在我的 Ubuntu 18.04LTS 中，为什么继续出现以下问题：

$ flutter doctor -v

! Doctor found issues in 1 category.

与 StackOverflow 中的另一个类似问题不同，在我安装 flutter 插件之前，“[✓] Android Studio (version 3.4)”等于“[!] Android Studio”，并具有相同的错误消息。在我安装了 flutter 插件（和 dart）后，只有“[!] Android Studio”仍然显示错误。

有人知道为什么吗？我在我的文件中进行了很多搜索，我只安装了一个 Android Studio。为什么显示两个？ “[!] Android Studio”指的是什么？命令“$ flutter doctor”有问题吗？

这篇文章适用于那些已经安装了插件但仍然收到警告的人。

Note: The Flutter team has created an issue for the inability of doctor to detect installed plug-ins. It's a know issue and they are looking to deprecate this detection feature of doctor:

• https://github.com/flutter/flutter/issues/61246 https://github.com/flutter/flutter/issues/61246

我的 flutter 和 dart 插件已正确安装，但我仍然收到警告。

[!] Android Studio (version 4.0)
    ✗ Flutter plugin not installed; this adds Flutter specific functionality.
    ✗ Dart plugin not installed; this adds Dart specific functionality.
  

就我而言，忽略警告效果很好。

我多次尝试重新安装插件，但还是不行没有删除警告 from flutter doctor.

然而，一切工作正常。我可以成功创建并运行从以下位置创建的应用程序

• 命令行与flutter create
• 来自 Android StudioFile->New->New Flutter Project

我使用的是 Ubuntu 20.04 LTS 和 Android Studio 4.0.1（通过安装JetBrains 工具箱 https://www.jetbrains.com/toolbox-app/)

我通过 snap store 安装了 flutter：

sudo snap install flutter --classic
sudo snap install flutter-gallery
flutter channel dev
flutter upgrade
flutter config --enable-linux-desktop

# wanted to try web, apparently requires beta channel
flutter channel beta
flutter channel upgrade
flutter config --enable-web

仅供参考，我花了一段时间才了解 Flutter SDK 的位置。是这里：/home/(username)/snap/flutter/common/flutter

Plugins installed correctly, but still get warning:
