[当我在模拟器和真实设备上打开相机时，应用程序崩溃

Question

我想运行相机时，我的应用程序崩溃。而我收到此错误，请参见下文

 import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
    var bridge: FlutterBridge?

    override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
    ) -> Bool {
        if #available(iOS 10.0, *) {
            UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate
        }

        let controller = window?.rootViewController as! FlutterViewController
        bridge = FlutterBridge(controller: controller)

        GeneratedPluginRegistrant.register(with: self)
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }

错误：线程1：异常：“必须先配置默认的Firebase应用程序实例，然后才能初始化默认的Firebase Vision实例。一种确保在默认情况下调用[FIRApp configure];（或Swift中的FirebaseApp.configure()）的方法。应用程序代表的application:didFinishLaunchingWithOptions:（或application(_:didFinishLaunchingWithOptions:)）。“

有人知道我必须做什么？
