Description

Here is my payload

{
"message": {
"token": "my device token",
"data": {
"title": "Custom Notification",
"body": "This is a custom notification with actions.",
"click_action": "FLUTTER_NOTIFICATION_CLICK"
},
"android": {
"priority": "high"
}
}
}

I JUST WANT TO USE CUSTON NOTIFICATION (NOT DEFAULT ONE)
NOTE:- in default notification everything is working fine nut what if i need to use my own custom notification with action etc

when i change payload from this to give below its working fine when app in launched from notification when app is terminated

i am getting issue only when app is terminated and launched from notification tap

{
"message": {
"token": "my device token",
"notification": {
"title": "Custom Notification",
"body": "This is a custom notification with actions.",
},
"android": {
"priority": "high"
}
}
}

i am using data:{} instead of notification:{} because notification trigger default push notification:- i am using my custom notification and working fine when app is foreground and background but not in case when app is terminated and launched from notification tap

please suggest:-
FirebaseMessaging messaging = FirebaseMessaging.instance;
RemoteMessage? initialMessage = await messaging.getInitialMessage();

this method is not working when i used data:{} in payload

@DeepakYiron, could you please provide a minimal code sample that uses only FlutterFire plugins? This will help us isolate the issue effectively. Additionally, ensure the code is properly formatted for clarity. Thank you!

Hi @DeepakYiron, the formatting still isn’t correct, and the code should be as minimal as possible. If you’re having trouble creating a minimal reproducible example, please refer to this guide for assistance.
