avoid_catching_errors

Don't explicitly catch Error or types that implement it.

此规则自 Dart 2.0 版本起可用。

DON'T explicitly catch Error or types that implement it.

Errors differ from Exceptions in that Errors can be analyzed and prevented prior to runtime. It should almost never be necessary to catch an error at runtime.

BAD:

try {
  somethingRisky();
} on Error catch(e) {
  doSomething(e);
}

GOOD:

try {
  somethingRisky();
} on Exception catch(e) {
  doSomething(e);
}

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

linter:
  rules:
    - avoid_catching_errors
