Answer 1

Wait for the upgrade to Flutter 1.22.2

See this issue : https://github.com/flutter/flutter/issues/67986

... and the post on Google groups:

Hi,

Flutter 1.22.2 has been released to stable. This is a hotfix release on the 1.22 branch and also includes a hotfixed Dart 2.10.2 version. Changes for this build are listed below and are available on the Flutter Wiki here: Hotfixes to the Stable Channel.

This fixes the following issues:

https://github.com/flutter/flutter/issues/67869 - Stylus tap gesture is improperly registered.

https://github.com/flutter/flutter/issues/67986 - Android Studio 4.1 not properly supported.

https://github.com/flutter/flutter/issues/67213 - Webviews in hybrid composition can cause a crash.

https://github.com/flutter/flutter/issues/67345 - VoiceOver accessibility issue with some pages.

https://github.com/flutter/flutter/issues/66764 - Native webviews may not be properly disposed of in hybrid composition.

Thanks!

Answer 2

在 Android Studio 的设置中打开 Plugins，搜索 Flutter 并安装它，它也会用它安装 dart 插件，然后重新启动 Android Studio

Answer 3

Open Android Studio -> Go to Settings -> Go to Plugins and check that Dart and Flutter plugins are installed on Android studio
