异常处理

Future<Null> main() async {
//注册Flutter框架的异常回调
FlutterError.onError = (FlutterErrorDetails details) async {
  //转发至Zone的错误回调
  Zone.current.handleUncaughtError(details.exception, details.stack);
};
//自定义错误提示页面
ErrorWidget.builder = (FlutterErrorDetails flutterErrorDetails) {
  return ErrorPage();
};
//使用runZone方法将runApp的运行放置在Zone中，并提供统一的异常回调
runZoned<Future<Null>>(() async {
  runApp(MyApp());
  //设置帧回调函数并保存原始帧回调函数
//    orginalCallback = window.onReportTimings;
//    window.onReportTimings = onReportTimings;
  if (Platform.isAndroid) {
    SystemUiOverlayStyle systemUiOverlayStyle = SystemUiOverlayStyle(
      statusBarColor: Colors.transparent, //设置为透明
    );
    SystemChrome.setSystemUIOverlayStyle(systemUiOverlayStyle);
  }
