将哨兵添加到Flutter的正确方法

Question

从https://flutter.dev/docs/cookbook/maintenance/error-reporting，

runZoned<Future<void>>(() async {
  runApp(CrashyApp());
}, onError: (error, stackTrace) {
  // Whenever an error occurs, call the `_reportError` function. This sends
  // Dart errors to the dev console or Sentry depending on the environment.
  _reportError(error, stackTrace);
});

但是我的IDE表示onError已过时。

解决此问题的正确方法是什么？我在runZonedGuarded上找不到任何示例。

Answer 1

在Flutter 1.17.0 became obsolete上看起来像(It's a breaking change from Dart 2.8)。您可以这样：

runZonedGuarded(() {
  runApp(CrashyApp());
}, (Object error, StackTrace stackTrace) {
  // Whenever an error occurs, call the `_reportError` function. This sends
  // Dart errors to the dev console or Sentry depending on the environment.
  _reportError(error, stackTrace);
});

Answer 2

这是对我有用的设置：
