I want to make an app which sends number that means just suppose user A sends 10 from his app to user B and also suppose user S has 100 number already in his app , when A sends it becomes 110 in B’s app and vice versa.
Where should i start , cant understand.
this way … this picture says the word.
When A send amount minus the amount from the original and save. And in the receiver user id point tag value add the sent amount with the existing amount and save into it. By using firbase data On changed block you can show it to all concern users
When use selects the user id to whom he want to send, immediately get hus existing amount into a label.
After entering amount in a box and clicked send button, do the maths operation and save the values into the respective user ids.
So by using forbade data on changed block, once value updated, it will be reflected in the concern users app
