FlutterError.onError是一个方法，允许你连接到Flutter框架的错误处理机制，这样你就可以在构建、布局或绘制阶段发生错误时接收回调。
runZonedGuarded是一个实用函数，允许你在一个新区域中运行一段自定义错误处理程序的代码块。onError参数是在区域内发生错误时将被调用的错误处理程序。
总之：
- FlutterError.onError是特定于Flutter框架的，用于处理构建、布局和绘制阶段的错误。
- runZonedGuarded.onError更通用，允许你在新区域中运行一段自定义错误处理程序的代码块，可用于更广泛的错误处理需求。
是的，FlutterError.onError和runZonedGuarded.onError可以在Flutter应用程序中一起使用。
例如，你可以使用FlutterError.onError来处理在构建、布局或绘制阶段发生的错误，然后使用runZonedGuarded.onError来处理发生在特定代码块内的错误。
这样，你可以在Flutter应用程序中拥有多个错误处理程序，以处理不同部分代码中不同类型的错误。
英文:
FlutterError.onError is a method that allows you to hook into the Flutter framework's error-handling mechanism, so you can receive callbacks when an error occurs during the build, layout, or painting phases.
runZonedGuarded is a utility function that allows you to run a block of code in a new zone with a custom error handler. The onError parameter is the error handler that will be called if an error occurs within the zone.
So, in summary:
- FlutterError.onError is specific to the Flutter framework and is used
to handle errors during the build, layout, and painting phases. - runZonedGuarded.onError is more general and allows you to run a block
of code in a new zone with a custom error handler, which can be used
for a wider range of error-handling needs.
Yes, FlutterError.onError and runZonedGuarded.onError can be used together in a Flutter application.
For example, you can use FlutterError.onError to handle errors that occur during the build, layout, or painting phases, and use runZonedGuarded.onError to handle errors that occur within a specific block of code.
In this way, you can have multiple error handlers in your Flutter application to handle different types of errors in different parts of the code.
