title: Flutter "Create 2 missing Overrides" bug?
body: <p>When I try adding missing Overrides with Quick fix e.g. here: <code>class CirclePainter extends CustomPainter {}</code>, the result is completely buggy:</p>
  <pre><code>class CirclePainter extends CustomPainter {
    @override
    void paint(Canvas canva canva canvas, Si Si Size size) {
        // TODO: implement paint
      }
    
      @override
      bool shouldRepa(Canvas canvan canvas, Sigate) {
      // TODO: implement shouldRepaint
      throw UnimplementedError();
    }
  }
  </code></pre>
  <p>Not a big problem here but when I want to add 10 or more missing overrides I have to change every single one per hand.</p>
