title: How to use 4-space wide tab character in Android Studio?
body: <p>I'm creating a Flutter app in android studio. Under Settings -> Editor -> Code Style -> Dart, I enabled "use tab character" and changed the tab size and indent to 4.</p>
  
  <p>However, nothing seemed to have changed in the main.dart file, so I used Ctrl-Alt-Shift-L to reformat the code (even tried with "code cleanup" enabled), but it still uses two spaces to indent.</p>
  
  <p>How do I make android studio use tab characters?</p>
