You can solve that by navigating to your flutter install directory and run
flutter upgrade
There are manual update to be done, but the above command will handle that for you.
You can easily remove this error by update your Dart and Flutter plugin.
Just go to file -> close project
Click on Configure which is shown bottom right in the screen -> Plugins
Search Dart and update and then search flutter and update and restart studio
4.Your problem is resolved you can create fresh project successfully

I have tried uninstalling and reinstalling AndroidStudio. Plugins are configured in AndroidStudio.
Any help would be appreciated
Flutter doctor in android studio will only work properly after setting up the paths of their sdks in android settings for both: flutter & dart.
Checkout File > Settings > Languages & Frameworks > dart & flutter and set their paths there. It will start working after that.
This works for me.
I don't know why I'm getting this error when I am running my project I would appreciate if some one could help me. I'm new to Flutter and Android Studio.

You appear to have CocoaPods installed but it is not working.
This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it.
This can usually be fixed by re-installing CocoaPods. For more info, see https://github.com/flutter/flutter/issues/14293.
To re-install CocoaPods, run:
sudo gem install cocoapods

It's likely that gradlew isn't set as an executable on your machine, and causes ProcessException: Permission Denied errors. Try running chmod +x gradlew on your Mac OS.
After upgrading Android Studio to (3.4) and my Flutter Plugin to (38.2.1), the option to create a new project is missing from the Android Studio startup screen. I've tried the following things detailed below. Any suggestions to fix this would be greatly appreciated.

In Android Studio, verified that Android Studio->Plugins shows Flutter and Dart plugins are enabled.
In Android Studio, verified that Android Studio->Preferences->Languages & Frameworks shows Flutter and Dart are supported.
After upgrade, exited Android Studio and restarted MAC.
As a work around, I'm creating a new project from the command line, and then editing and running the project from Android Studio.
Android studio and VS code show me both no devices but flutter doctor shows no issues and the flutter run command runs the app fine
Output in Terminal:
flutter doctor -v
