Hello I'm new to FlutterFlow and developing an app where users can spend in-app credits. I need assistance with setting up an input field that includes custom form validation. Specifically:
The input field should only accept numeric values greater than 1 and less than or equal to the user's wallet balance.
Once the user places an order, the entered amount should be deducted from their wallet balance.
I'm seeking guidance and advice on how to implement this functionality effectively in FlutterFlow.
