snippet.dart

import 'package:flutter/material.dart';
import 'dart:ui';

Future<void> main() async {
  await myErrorsHandler.initialize();
  FlutterError.onError = (details) {
    FlutterError.presentError(details);
    myErrorsHandler.onErrorDetails(details);
  };
  PlatformDispatcher.instance.onError = (error, stack) {
    myErrorsHandler.onError(error, stack);
    return true;
  };
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      builder: (context, widget) {
        Widget error = const Text('...rendering error...');
        if (widget is Scaffold || widget is Navigator) {
          error = Scaffold(body: Center(child: error));
        }
        ErrorWidget.builder = (errorDetails) => error;
        if (widget != null) return widget;
        throw ('widget is null');
      },
    );
  }
}
