如何删除通知徽章-Flutter

Question

我有 flutter 应用程序，我在其中使用推送通知

当我收到新通知时，我会删除所有通知和徽章，但有时在打开应用程序时通知徽章不会删除并且它会不断增加

这是我发现删除徽章的解决方案：-

ios->appDelete.swift

import UIKit
import Flutter
import Firebase
import UserNotifications

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    FirebaseApp.configure()
    GeneratedPluginRegistrant.register(with: self)

      if #available(iOS 10.0, *) {
                application.applicationIconBadgeNumber = 0 // For Clear Badge Counts
               let center = UNUserNotificationCenter.current()
               center.removeAllDeliveredNotifications()
                center.removeAllPendingNotificationRequests()
                center.delegate = self  as? UNUserNotificationCenterDelegate
            }

       return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

但它不会删除我的徽章有没有办法删除通知徽章？

Answer 1

尝试在didFinishLaunchingWithOptions之后在AppDelegate.swift中添加以下代码

override func applicationDidEnterBackground(_ application: UIApplication){
   application.applicationIconBadgeNumber = 0
}

希望它对你有用
