I'm want to fetch API every 15min and check if anything changes. Then if it does send push notification to inform the user about changes. Now my problem is that I cannot get to run the check on IOS. Does anyone have a solution for this?
There is a tool: https://pub.dev/packages/background_fetch, but it's not the perfect Dart solution for iOS to schedule background tasks as android when the app terminates, so try using Alarm Manager and
Flutter WorkManager
Also, you can try native side implementation with BGTaskScheduler

is there a way to display incoming call notifications when the flutter app is terminated or in the background? I tried to use connectyCube package, but too complex. Also, I used the flutter background service to listen to incoming calls with socket.io but the app got crashed when it is launched from the background. I need your guidance.
You can use native code in android for incoming call notification.
For Android you can use HeadsUpNotificationService as we use in native.
And for Ios you can use https://github.com/peerwaya/flutter_call_kit
Actually I was trying to implement background process (fetch data from api) even the app is terminated in my flutter project how can I achieve in both Android & iOS platforms.
Have you ever wanted to execute Dart code in the background—even if your app wasn’t the currently active app?
The mechanism for this feature involves setting up an isolate.
Isolates are Dart’s model for multithreading, though an isolate
differs from a conventional thread in that it doesn’t share memory
with the main program. You’ll set up your isolate for background
execution using callbacks and a callback dispatcher.
Example
but if you want do that when app terminated, you will have to wakeup app through Workmanager or some another approach like sending firebase push notification or wakeup app in scheduled time with flutter alarm manager or something like that
I am trying to make a new todo tasks app and its offline no intternet needed...
I want to get reminded when the tasks time is up
i tried using local notification it worked as showing notification but for my phone as the README section of the package said that it doesnt work for everybody's phone for such android things... So when i terminate my app or having it on my backgroud and wait for the schedule notification nothing appear...
So any idea of how i can let my app work on backgroud
for the solution i used workmanager so it run my app after a while in the background and push my local notification to the user
welp its hard to it for every 1 sec cause the work manager only make a loop and activate every 15 min..
workmanager is a flutter package you can use for free :3
I am implementing a video call feature in Flutter with the help of Firebase Cloud Messaging,
it's working fine in foreground.
my doubt is
while app is in background I need to get a receiving call same like as WhatsApp in both Android and IOS .... is it possible in flutter?
yes. it is possible by the combination of push notification and flutter_callkeep to show the upcoming call screen.
Or if you want to run the background process you need to refer to Method Channels, and here is a post about creating a service for running app in the background. also background_fetch is a useful package for background process.
I have searched Google, YouTube and stack overflow for the answer but I haven't found any real solution.
I want to implement my own push notification solution on flutter, without firebase nor One signal. I do not want to depend on a third party service.
My Backend is on GoLang with graphql.
On the frontend, I am using a block pattern (flutter_bloc v6) and graphql_flutter v4.
I am using graphql subscriptions, so whenever the Backend emits a signal, the flutter app is able to receive it immediately.
I would like to be able to push up notifications to my users whenever the Backend sends some information, no matter if the app is on the foreground, background, closed or whatever. I do not want scheduled notifications either (aka flutter_local_notifications)
Do you want to use a third service other than firebase/one signal?
Then you can try airship(https://docs.airship.com/reference/messages/message-types/push-notifications/)
But if you want to setup your own provider server, please check this page(https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server), this is the start point, from where you can start your investigation and development.
Then you have to create your own backend system to send push notifications to the device. You have to develop Native Application for iOS and Android going beyond flutter. The local push notification could be used but you need to develop a custom notification receiver that will respond to the notification call back from the server in the background.
