BoostNavigator.instance.pop(); 不会触发WillPopScope v3.0-null-safety-release.2.1
放AppDelegate.swift里 ``` override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { let deviceTokenStr = [UInt8](deviceToken).map{String(format: "%02x", $0)}.joined() NSLog("deviceToken：--------> " + deviceTokenStr) UserDefaults.standard.set(deviceTokenStr, forKey: "push_device_token") } ```
