【问题描述】：

我正在尝试在 iOS 上运行 Flutter 应用，但出现白屏异常：

libc++abi: terminating with uncaught exception of type NSException

*** 由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“FLTWakelockApi api 不响应 @selector(toggleMsg:error:)” 以 NSException 类型的未捕获异常终止 CoreSimulator 757.5 - 设备：iPhone 12 Pro Max (A59923DB-2B0D-42DF-8D68-DCB8A7B7866D) - 运行时：iOS 14.5 (18E182) - 设备类型：iPhone 12 Pro Max (lldb)

这是我的 AppDelegate 代码

import UIKit
import Flutter
import GoogleMaps
import Firebase
import UserNotifications

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
    override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        // TODO 1.4 - Shipping Address - Google API Key ???? 
        GMSServices.provideAPIKey("AIzaSyDnBpxFOfeG6P06nK97hMg01kEgX48JhLE")
        GeneratedPluginRegistrant.register(with: self)
        if #available(iOS 10.0, *) {
            application.applicationIconBadgeNumber = 0 // Clear Badge Counts
        }
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }

    override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        // Pass device token to auth
        Auth.auth().setAPNSToken(deviceToken, type: .prod)
        
        super.application(application, didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)
    }

    override func application(_ application: UIApplication,
                              didReceiveRemoteNotification notification: [AnyHashable : Any],
                              fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        if Auth.auth().canHandleNotification(notification) {
            completionHandler(.noData)
            return
        }
        
        super.application(application, didReceiveRemoteNotification: notification, fetchCompletionHandler: completionHandler)
    }
    
    override func application(_ application: UIApplication, open url: URL,
                              options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
        if Auth.auth().canHandle(url) {
            return true
        }

        return super.application(application, open: url, options: options)
    }
}

Please check image which shows error in AppDelegate

我尝试过清洁豆荚从头开始创建应用程序以及类似的一切就像 firebase 说的那样添加代码，仍然只能得到白屏。

检查这是否回答了您的问题github.com/Sub6Resources/flutter_html/issues/843
您在“异常”上设置了一个断点，这样您就可以进行调试，并且您的程序将在抛出异常时停止。

【解决方案1】：

将您的wakelock 降级到版本0.5.3+3。为了安全起见，请将其添加到您的dependency_overrides。最后，您的 pubspec.yml 部分应该如下所示

dependency_overrides:
  wakelock: 0.5.3+3
