Flutter "Entrypoint isn't within the current project." error on Android Studio

Question

Flutter app runs on VS Code with Start Debugging & Run Without Debugging and also with terminal command "flutter run" . However it runs on Android Stuido only with terminal command "flutter run".

When I try to run it on Android Studio, with the play button which triggers the build, I get this error : "Entrypoint isn't within the current project."

Invalidate Caches and Restart, flutter clean, quitting and restarting Android Studio are some options I tired with no success at all.

Have any of you faced the same issue? What can be the problem? And please the solution...

Thanks in advance, Oz

Answer 1

For me, right clicking on the root Flutter project and selecting "Mark Directory As" -> "Sources Root" fixed the issue.

Answer 2

It works for me, hope it will work for everyone. Goto File -> Project Structure -> Module Or in edit configuration, just name it "main" and locate the location of 'main.dart' file in the Dart entrypoint text field.
Please take a look at the below screenshot.

Click on File-> Project Structure -> Module then add root folder of your project then it will detect its a flutter app and then build
