How to specify if Intellij / Android Studio treats a project as Dart vs Flutter

[MisterJimson]

Steps to Reproduce

1. Open a Flutter or Dart project
2. Right click on test file or folder, Run or Debug tests
3. Observe output and see if the Flutter SDK is being used, or if the Dart SDK is being used
   3.1. Flutter SDK: flutter test ........
   3.2. Dart SDK: pub run test ........

If the wrong command is used for the project, running or debugging will fail. How do we configure the project so the IDE uses the correct tool?

Right click on test file, run, results in this:

Right click on test file, debug, results in this:

Running flutter test on the cli works fine, and the Flutter SDK path is correctly configured in the IDE.

How do we configure the project so the IDE uses the correct tool?

For a Dart project: open the Dart settings/preferences and set the SDK to one not distributed with Flutter. Do not set the Flutter SDK.

For a Flutter project: open the Flutter settings/preferences and set the SDK, but do not set the Dart SDK. The Dart SDK will automatically be set to the one distributed with the Flutter SDK.
