anchor.diff:  void main() async {
     await doSomething();
   
  -  // ignore: unawaited_futures
  -  doSomething(); // Explicitly-ignored fire-and-forget.
  +  unawaited(doSomething()); // Explicitly-ignored fire-and-forget.
   }
   ```
   
  
positive.code: It's easy to forget await in async methods as naming conventions usually don't
  tell us if a method is sync or async (except for some in `dart:io`).
  
  **GOOD:**
  ```
  Future doSomething() => ...;
  
negative.code: import 'package:analyzer/dart/element/element.dart';
  import 'package:linter/src/analyzer.dart';
  
  const _desc = r'`Future` results in `async` function bodies must be '
      '`await`ed or marked `unawaited` using `package:pedantic`.';
