DO await functions that return a Future inside of an async function body.

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).

When you really do want to start a fire-and-forget Future, the recommended way is to use unawaited from dart:async. The // ignore and // ignore_for_file comments also work.


void main() async {
  doSomething(); // Likely a bug.


Future doSomething() => ...;

void main() async {
  await doSomething();

  unawaited(doSomething()); // Explicitly-ignored fire-and-forget.
