In my flutter app, I am trying to configure push notification using cloud functions, but I am facing a problem where my firebase console sends the notification based on the cloud function trigger as intended but I am not able to receive the notification on my android emulator. I console log the message and I noticed that the notification message is being sent successfully by the Firebase console but I don't receive the message on my emulator. When I try printing the message on the home page I get this: on message: {body: null, title: null}, data: {recipient: sjjsjnhhaksdijadjifjhhabdbfhakdjf}}, and my emulator is not showing a snack bar with a message either as intended. These are my codes below. please I need help.
this part of the cloud function code to listens to new document on
the`activity path and to send notification
exports.onCreateActivityNotification = functions.firestore
.document('/activities/{userId}/userActivities/{userActivities}')
.onCreate(async (snapshot, context) => {
console.log('activity notification created', snapshot.data());
//getting user connected to the activity
const userId = context.params.userId;
const createdActivityItem = snapshot.data();
const usersRef = admin.firestore().doc(`users/${userId}`);
const doc = await usersRef.get();
const androidNotificationToken =
doc.data().androidNotificationToken;
//checks if user has an androidnotification token
if(androidNotificationToken){
//sennds notification if users has a token
sendNotification(androidNotificationToken, createdActivityItem )
} else {
console.log('no notification token');
}
//function for sending notification
function sendNotification(androidNotificationToken, userActivities)
{
let body;
switch (userActivities){
case userActivities.comment !== null:
body = `${userActivities.fromUserId} commented :
${userActivities.comment}`
break;
case userActivities.comment === null:
body = `${userActivities.fromUserId} liked your punch`
break;
default:
break;
}
//creates message for push notification
const message = {
notification: {body: body},
token: androidNotificationToken,
data: {recipient: userId},
};
//sends message with admin.messaging()
admin
.messaging()
.send(message)
.then(response => {
return console.log('message sent', response);
}).catch(error =>{
console.log('error sending message', error);
})
}
});
//code for the home page. This is the part of the code to display the
// notification on the emulator
//configuring the notification
_configureNotification() {
final String currentUserId =
Provider.of<UserData>(context, listen: false).currentUserId;
if (Platform.isIOS) getIosPermission();
_firebaseMessaging.getToken().then((token) => {
print('firebase messaging token: $token'),
//associating device token with current user
usersRef
.document(currentUserId)
.updateData({'androidNotificationToken': token})
});
//displaying notification from cloud function
_firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print('on message: $message\n');
final String recipientId = message['data']['recipient'];
final String body = message['notification']['body'];
//checking if recipientId is equal to currentuserId before
//sending notification
if (recipientId == currentUserId) {
print('notification shown');
