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<UISceneSession>) {
    // 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.
  }
}

解决方案

[Ali-Zameen89]

We are witnessing that flutter boost isn't picking up routes that we provide from native iOS side.

[Ali-Zameen89]

When we create a dummy Flutter Engine, we are able to silence these exceptions but our native pigeon communications don't work with FlutterBoost engine's binary messenger.

var flutterEngine = FlutterEngine(name: "FlutterBoostPlugin") flutterEngine.run() GeneratedPluginRegistrant.register(with: flutterEngine)
