请描述遇到的问题，以及您所期望的正确的结果

Either the assertion indicates an error in the framework itself,

请说明如何操作会遇到上述问题

flutter_boost初始化的时候，flutter端通过FlutterError.onError = (details) {
print(details.toString());
};捕捉错误输出

在下面填入关键复现代码

iOS 端代码：
#import "GMAppDelegate.h"
#import <FlutterBoost.h>
#import <Flutter/Flutter.h>

@interface GMAppDelegate()

@EnD
@implementation GMAppDelegate

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary )launchOptions
  {
  FlutterBoostSetupOptions options = [FlutterBoostSetupOptions createDefault];
  options.dartEntryPointArgs = @[ @"I'm from IOS!", @"--for-test" ];
  [[FlutterBoost instance] setup:application delegate:self callback:^(FlutterEngine *engine) {

   } options: options];
  

  return YES;
  }

• (void)popRoute:(FlutterBoostRouteOptions *)options {

}

• (void)pushFlutterRoute:(FlutterBoostRouteOptions *)options {

}

• (void)pushNativeRoute:(NSString *)pageName arguments:(NSDictionary *)arguments {

}

@EnD

flutter 端代码：

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_boost/flutter_boost.dart';
class CustomFlutterBinding extends WidgetsFlutterBinding
with BoostFlutterBinding {}
void main() {
FlutterError.onError = (details) {
print(details.toString());
};
CustomFlutterBinding();
return runZonedGuarded(() => const MyApp(), (error, stack) {
print(error.toString());
print(stack.toString());
});
}

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

@OverRide
State createState() => _MyAppState();
}

class MyAppState extends State {
static Map<String, FlutterBoostRouteFactory> routerMap = {
'homepage': (settings, uniqueId) {
return PageRouteBuilder(
settings: settings,
pageBuilder: (, __, ___) => MyHomePage(title: 'title'));
},
};

Route? routeFactory(RouteSettings settings, String? uniqueId) {
FlutterBoostRouteFactory? func = routerMap[settings.name!];
if (func == null) {
return null;
}
return func(settings, uniqueId);
}

@OverRide
Widget build(BuildContext context) {
return FlutterBoostApp(routeFactory,
// 如果自定了appBuilder，需要将传入的参数添加到widget层次结构中去，
// 否则会导致FluttBoost初始化失败。
appBuilder: (child) => MaterialApp(
home: child,
));
}
}

class MyHomePage extends StatefulWidget {
const MyHomePage({super.key, required this.title});

final String title;

@OverRide
State createState() => _MyHomePageState();
}

class _MyHomePageState extends State {
int _counter = 0;

void _incrementCounter() {
setState(() {
_counter++;
});
}

@OverRide
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
const Text(
'You have pushed the button this many times:',
),
Text(
'$_counter',
style: Theme.of(context).textTheme.headlineMedium,
),
],
),
),
floatingActionButton: FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: const Icon(Icons.add),
), // This trailing comma makes auto-formatting nicer for build methods.
);
}
}

错误输出是在 FlutterError.onError = (details) {
print(details.toString());
};里面打印的

复现的平台

Both

Flutter SDK版本

3.19.0

FlutterBoost版本

5.0.1

是否延迟初始化FlutterBoost

No
