如何在flatter应用中禁用云消息?

我正在制作一个带有推送通知的应用程序。这些已经通过FirebaseMessaging实现。

_firebaseMessaging = new FirebaseMessaging();
  _firebaseMessaging.configure(
    onMessage: (Map<String, dynamic> message) {
      print("Message: " + message.toString());
    },
    onResume: (Map<String, dynamic> message) {
      print("Message: " + message.toString());
    },
    onLaunch: (Map<String, dynamic> message) {
      print("Message: " + message.toString());
    },
  );
  _firebaseMessaging.getToken().then((token) {
    print(token);
  });
