only_throw_errors

Only throw instances of classes extending either Exception or Error.

此规则自 Dart 2.0 版本起可用。

DO throw only instances of classes that extend dart.core.Error or dart.core.Exception.

Throwing instances that do not extend Error or Exception is a bad practice; doing this is usually a hack for something that should be implemented more thoroughly.

BAD:

void throwString() {
  throw 'hello world!'; // LINT
}

GOOD:

void throwArgumentError() {
  Error error = ArgumentError('oh!');
  throw error; // OK
}

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

linter:
  rules:
    - only_throw_errors
