Hello,
So i created this app design where you can keep track of your current weight. You select a number (which is your current weight) and save it. It saves the number in a Firebase collection list, which works untill you put the same number twice.
For example, i add 72, then 72,3 then 72 again, it's not saving it because its used before and already in the list. Any unique number works tho...
Does anyone know how i can fix this?
