my button is set up to update a firebase document and then send a push notification to a list of users from the user collection. however this seems to be throwing an error that i cant seem to fix from the FF console. I have already checked my firebase functions including Fcm_tokens, the fcm_tokens are being created fine. and Im able to send notification via FF console. Just doesnt work from the phone (physical) - and the user is logged in and i've also done the AllUsers permission to call fcm_token function
i feel this has something to do with the flutter packages being used in the background , esp the ones serialization helpers are using.
Anyone come across these kinda error logs?
this is my error log:
