Here is the flutter doctor result:
[√] Flutter (Channel stable, 1.22.1, on Microsoft Windows [Version 10.0.18362.30], locale en-US)
[√] Android toolchain - develop for Android devices (Android SDK version 30.0.2)
[!] Android Studio
X Flutter plugin not installed; this adds Flutter specific functionality.
X Dart plugin not installed; this adds Dart specific functionality.
[!] Connected device
! No devices available
! Doctor found issues in 2 categories.
I have already installed the flutter plugin. But the problem still exists. How can I fix this?
回答1:
Since you say you have flutter plugin installed in Android Studio, and if Android Studio correctly shows your installed plugin, there is no reason to believe any third-party tool reporting otherwise.
Also, this will not affect your flutter development and your IDE plugins will work as expected inside the IDE and flutter tool's commands work independent of the IDE in use.
Android Studio 4.1 apparently changed its default plugin install path.

Flutter does not directly use the IDE plugins, so doctor failing to detect them does not affect any behavior (it's just annoying).
回答2:
open terminal: Mac User: flutter config --android-studio-dir=/Applications/Android\ Studio.app
回答3:
Reinstall Flutter Plugin from Android Studio
回答4:
Are you using Android Studio V 4.1? With Android Studio V4.1 there is a problem. Try to reinstall Android Studio but Version 4.0.1 and try it again, chances are this will fix your problem.
回答5:
- open terminal:
- run> flutter channel dev
- run> flutter channel updrade
回答6:
change channel master to dev. then upgrade.
flutter channel dev
flutter channel upgrade
try again
flutter doctor
Note: I think it's Android Studio 4.1 issue...

Well hello all
I would suggest you all to follow the steps what flutter documentation sites tells you to do
For windows I'm talking(dont know about the mac OS, Linux,and other OS)-->There are some people who got detected flutter and dart plugins by the flutter doctor and few are not
I got this issue when I tried to install ... I did everything like installed flutter and dart plugin still my flutter doctor haven't detected the plugins ...
There are n number of reasons you will find in different sites and also in Github issues why the flutter doctor is unable to detect plugins though you installed plugins and followed each and every steps which is mentioned on documentations
following steps worked for me
flutter channel dev
flutter upgrade
flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"
flutter doctor -v
note :--- flutter config --android-studio-dir="C:\Program Files\Android\Android Studio" should be example flutter config "C:\Program Files\Android\Android Studio"
above steps worked for me i hope it will helps you too :)

- Open Android studio
- Follow the Path Configure > Plugins > marketplace > search Flutter & Dart > Install
- Restart IDE(Android studio)
- Open Terminal and Export Flutter Path

If you are upgrading for an existing project:
Run
git clone https://github.com/flutter/flutter.git
in your terminal.
The be sure to delete the Flutter folder in your App's root directory. Otherwise you will get over 50k errors popping up
