[Bug]: FlutterBoost exceptions on iOS.

### 请描述遇到的问题，以及您所期望的正确的结果

```

```

### 请说明如何操作会遇到上述问题

1. flutter build ios-framework
2. Take out debug xcframeworks and add in a sample project.

### 在下面填入关键复现代码

```
@main
class AppDelegate: UIResponder, UIApplicationDelegate {

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.

let delegate = BoostDelegate()

FlutterBoost.instance().setup(application, delegate: delegate, callback: { engine in
debugPrint(engine)
})

// FlutterBoost.instance().sendEventToFlutter(with: "appArgs", arguments: ["language": "en", "environment": "com"])
// FlutterBoost.instance().sendEventToFlutter(with: "loginUser", arguments: [:])

return true
}

// MARK: UISceneSession Lifecycle

func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}

func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set) {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
}

```

### 复现的平台

iOS

### Flutter SDK版本

3.16.9

### FlutterBoost版本

5.0.1

### 是否延迟初始化FlutterBoost

No

### 解决方案

Reproduce the issue with `flutter build ios-framework`, then add the debug XCFrameworks to a sample iOS project. Start with the stack traces in `flutter_boost/src/messages.dart`, `flutter_boost/src/flutter_boost_app.dart`, and the reported connectivity call; done means the sample project no longer produces these channel and plugin exceptions.
