unawaited_futures

Future results in async function bodies must be awaited or marked unawaited using dart:async.

此规则自 Dart 2.0 版本起可用。

此规则提供 快速修复 。

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.

BAD:

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

GOOD:

Future doSomething() => ...;

void main() async {
  await doSomething();

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

要启用 unawaited_futures 规则，请在你的 analysis_options.yaml 文件中，在 linter > rules 下添加 unawaited_futures ：

linter:
  rules:
    - unawaited_futures
