// Flutter - MAC OS - Error for a flutter project something about :
Migrate to android studio. With a link to the below web page
// Google Doc : https://developer.android.com/studio/intro/migrate
My Solution :
// I created a new flutter project with
flutter create test
// I opened the newly created project in android studio and then android
// studio popped up with required plugins and I installed the recommended
// plugins for the new project. Then Closed the project and...
// Next I opened my previous project which was showing me errors.
// And the error had disappeared.
