问题 In my app, I got a class "home" where the user is navigated to after he is authorized. Within "home" there is a PageView with BottomNavigationBar. When the user is getting a push notification from firebase (new message) he should be navigated to ChatHome and to the specific chat after tapping. How can I do this? Home does look like this @override Widget build(BuildContext context) { return Scaffold( key: _scaffoldKey, body: PageView( children: <Widget>[ Feed(userID: widget.userID), SearchView

问题 I'm using FCM for my push messages. Its great, however I've a client that needs to be able to remove a push message once its sent - (in case of mistakes / typos etc). I know you can get the message id from when the Topic is queued to send messages, just wondering if there is a way to then use that ID to expire those messages remotely. i.e. to delete the message. 回答1: There is currently no way to delete/remove a message from the server side/console.

问题 As I understand, when a message fails to be delivered, the Retry-After header is sometimes included in the response and sometimes not. But what happens if I first receives an error response with Retry-After included, resends the message and receives another error response but without Retry-After? I know I should use exponential backoff but how does that work when the previous waiting time was from the Retry-After header? Imagine this sequence of requests and responses: Request 1: No waiting

问题 I am currently writing an Android app using Flutter and a Node.js backend.
