Suggests keeping only one Notifier per file.

Example

❌ Bad:

class Some extends Notifier<int> {
  final int field = 0;

  @override
  int build() => 0;
}

// LINT: Prefer only one Notifier per file. Try moving this Notifier to a separate file.
class Another extends Notifier<int> {
  @override
  int get state;

  @override
  int build() => 0;
}

✅ Good:

some_notifier.dart

class Some extends Notifier<int> {
  final int field = 0;

  @override
  int build() => 0;
}

another_notifier.dart

class Another extends Notifier<int> {
  @override
  int get state;

  @override
  int build() => 0;
}
