How can i get notification in my app if the databse is updated i am using a sql database
You must have a service which is updating your sql database, from the same place call remote notification (considering you have FCM setup already)
@@CodeXdev i want to delete the user fcm token from database when a user uninstall the app
So i am checking whenever a notification is not sent to the user by my php code i am assuming that they uninstalled the app then i delete that token. Is it a right way to do it.
I think if user internet is not on then in this case notification will not be sent to them which leads to the deletion of their token
You dont need to delete token, only when someone login you update token.
Also, internet on/off is not a problem. FCM will deliver notification as soon as internet is available
@@CodeXdev I am storing the tokens in the database if someone uninstall the app then their token remains in the database which will consume unnecessary space
1st liker & comment... Mention my name please..
How did you replace the comments with blank space
Which comments? @TekSek
Oh, that code comments. I used regex //.* to find out all the lines which starts with // and then replaced with empty char
so.. my favorite game is playing with flutter errors !!! bammm
