flutter页面异常监测
在Flutter中，通常用FlutterError监测Flutter框架抛出的异常，用runZonedGuarded监测应用中用户代码异常。

class AppGuarded {
run(Widget app) {
//1. 用FlutterError监测flutter框架抛出的异常
FlutterError.onError = (FlutterErrorDetails details) async {
//线上环境，将异常交给zone统一处理
if (kReleaseMode) {
Zone.current.handleUncaughtError(details.exception, details.stack!);
} else {
//开发期间，走Console抛出
FlutterError.dumpErrorToConsole(details);
}
};

//2. runZonedGuarded监测整个用应用代码异常 不使用FlutterError默认只能捕捉业务代码异常
runZonedGuarded(() {runApp(app);
}, (e, s) => _reportError(e, s));

}

///通过接口上报异常
_reportError(Object error, StackTrace s) {
print(‘kReleaseMode:$kReleaseMod{e}^{\prime });print{(}^{\prime }catcherror:$error’);
}
}
