类型“WorkmanagerPlugin”没有成员“registerBGProcessingTask”iOS

Question

我正在尝试将 WorkManager 集成到 iOS 中（它已经在 Android 上适用于我）

当我运行该项目时，出现以下错误： `类型'WorkmanagerPlugin'没有成员'registerBGProcessingTask' /Users/user/Desktop/Projects/project/ios/Runner/AppDelegate.swift:23:22

无法为模拟器构建应用程序。 在 iPhone 15 Pro 上启动应用程序时出错。`

我已经阅读了该插件的官方文档，并且阅读了几个 iOS 集成示例，我还在插件存储库中看到了它的集成示例，并且我已经按照步骤进行操作，但与 iOS 上的 Android 不同，它对我不起作用.

mi AppDelegate.swift

import UIKit
import Flutter
import FirebaseCore
import workmanager
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
   
    if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
    }
    FirebaseApp.configure()
    GeneratedPluginRegistrant.register(with: self)
    WorkmanagerPlugin.setPluginRegistrantCallback { registry in  
            GeneratedPluginRegistrant.register(with: registry)
    }
    WorkmanagerPlugin.registerBGProcessingTask(withIdentifier: "task-identifier")
    
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

我已经审查了存储库中的问题并研究了有关该问题的更多信息，但其中给出的解决方案都不适合我......

尝试按照 iOS 上的操作文档的建议添加此行，但问题仍然存在...

WorkmanagerPlugin.setPluginRegistrantCallback { registry in  
            GeneratedPluginRegistrant.register(with: registry)
    }

我尝试过重新安装 YouTube pod 和指南，但问题始终是一样的，虽然我没有尝试过使用物理设备，但我不知道这是否是模拟器问题，尽管我不这么认为，因为他们使用了它在指南中...

我遇到了同样的错误并尝试了此解决方法。直接从 git 拉取 ios-bg-tasks-enh-final 版本。

workmanager:
    git:
      url: https://github.com/absar/flutter_workmanager.git
      ref: ios-bg-tasks-enh-final
