extension.dart

extension MapT<T extends Object> on T {
  Output map<Output>(Output Function(T) mapper) => mapper(this);
}

main.dart

void main(){
    String? str = null;
    str?.map(print);
}

Analyzer doesn't find quick-fix for extension importing:

But quick-fix is exists: import adding. main.dart

import 'extension.dart';

void main() {
  String? str = null;
  str?.map(print);
}

Desired behavior:

Quick-fix shows import extension.dart
