discarded_futures

Don't invoke asynchronous functions in non-async blocks.

此规则自 Dart 2.18 版本起可用。

此规则提供 快速修复 。

Making asynchronous calls in non-async functions is usually the sign of a programming error. In general these functions should be marked async and such futures should likely be awaited (as enforced by unawaited_futures).

DON'T invoke asynchronous functions in non-async blocks.

BAD:

void recreateDir(String path) {
  deleteDir(path);
  createDir(path);
}

Future<void> deleteDir(String path) async {}

Future<void> createDir(String path) async {}

GOOD:

Future<void> recreateDir(String path) async {
  await deleteDir(path);
  await createDir(path);
}

Future<void> deleteDir(String path) async {}

Future<void> createDir(String path) async {}

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

linter:
  rules:
    - discarded_futures
