[android-studio] How to find the path of Flutter SDK

The Flutter SDK path is certainly defined in a place where you can check it or change it, whether you created the project or not. Under Settings > Languages & Frameworks there should be a Flutter section. I found it by using the handy search bar in the Settings menu.

At the top of the Languages & Frameworks > Flutter is the Flutter SDK Path.

This is assuming that Flutter/Dart have already been installed under Plugins.
