flutter - 没有在 iOS 设备上获取 Firebase 通知，但是当我发送通知时抛出 Firebase 控制台，然后我收到了通知

Question

这是我的 AppDelegate.swift 文件导入 UIKit 导入 Flutter 导入 Firebase

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    FirebaseApp.configure()
    if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate
    }
    GeneratedPluginRegistrant.register(with: self)
    application.registerForRemoteNotifications()
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}
