I have integrated FCM with flutter and when I send data message from server its working fine. My question is how can I use onBackgroundMessage to open the app or specific screen. Actually I'm building video calling app using agora and I want to show incoming call screen like whatsapp using fcm if app is in background or closed. Right now I'm only printing the data. I have tried various methods but non of them are working. I have done this work on android because in android I can get the application context anywhere in-app. The issue is I'm not able to get the context in onBackgroundMessageHandler function.
Below is the code for showing the incoming call screen on foreground.
_firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print('on message $message');
if(message['data']['purpose'].toString().contains("video")){
Navigator.popAndPushNamed(context, IncomingCall.routeName, arguments: RouteIncoming(
int.parse(message['data']['clientid']), message['data']['token'], message['data']['username']
));
Provider.of<CallStatus>(context).setStatus(-1);
Provider.of<CallStatus>(context).setIncoming(-1);
}
else if(message['data']['purpose'].toString().contains("reject")) {
Provider.of<CallStatus>(context).setStatus(0);
}
else if(message['data']['purpose'].toString().contains("cancel")){
Provider.of<CallStatus>(context).setIncoming(0);
}
//_showMyDialog(message);
},
onBackgroundMessage: Platform.isIOS ? null : myBackgroundMessageHandler ,
onResume: (Map<String, dynamic> message) async {
print('on resume $message');
print(message['data']['token']);
Navigator.pushNamed(context, IncomingCall.routeName, arguments: RouteIncoming(
int.parse(message['data']['clientid']), message['data']['token'], message['data']['username']
));
},
onLaunch: (Map<String, dynamic> message) async {
print('on launch $message');
Navigator.popAndPushNamed(context, IncomingCall.routeName, arguments: RouteIncoming(
int.parse(message['data']['clientid']), message['data']['token'], message['data']['username']
));
},
);
Here is the code for myBackgroundMessageHandler
Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) async {
print("onBackgroundMessage: $message");
}
My PHP code for sending the FCM data message
$clientid = $this->input->post('clientid');
$userdata = $this->signin_model->send_token_m($clientid);
$url = 'https://fcm.googleapis.com/fcm/send';
$fields = array (
'registration_ids' => array (
"$userdata->firebase_token"
),
'data' => array (
"purpose" => "video",
"clientid" => $clientid,
)
);
$fields = json_encode ( $fields );
$headers = array (
'Authorization: key=' . "......",
'Content-Type: application/json'
);
$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_POST, true );
curl_setopt ( $ch, CURLOPT_HTTPHEADER, $headers );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $fields );
$result = curl_exec ( $ch );
echo $result;
