JetBrains code formatter should use dartfmt

[johnpryan]

I've been using the default JetBrains formatter without realizing it, and there are cases where it tries to format the code even though it is invalid Dart code. I'd prefer if the "Format code" action used dartfmt instead.

Steps to reproduce:

1. Run flutter create --empty new_project
2. Open project in Android Studio / IntelliJ
3. Delete the closing paren for the Scaffold widget:

import 'package:flutter/material.dart';

void main() {
  runApp(const MainApp());
}

class MainApp extends StatelessWidget {
  const MainApp({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: Scaffold(
        body: Center(
          child: Text('Hello World!'),
        ),
      ,
    );
  }
}

4. Run the "Reformat Code" action (not "Reformat code with dartfmt")
5. Observe weird output:

import 'package:flutter/material.dart';

void main() {
  runApp(const MainApp());
}

class MainApp extends StatelessWidget {
  const MainApp({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp
    (
        home: Scaffold(
    body: Center(
    child: Text('Hello World!'),)
    ,
    ,
    );
  }
}

Well, I guess that's a bug for JetBrains 😄 @stevemessick do you know where this should be directed?

I thought @alexander-doroshko had changed everything to use dartfmt years ago. But no, I can reproduce this problem.

Ideally, there would be an issue on https://youtrack.jetbrains.com to track this. @jwren might find this interesting, too.

Thanks, it's already tracked in YouTrack. Some details here and here. Sorry for the delay with these issues.

Thanks @stevemessick and @alexander-doroshko . Closing here.
