I did a few searches and couldn’t find any information on this, so I apologize if I’m missing any resources.
I would like to validate user input to ensure that the data entered is what I’m expecting. Is there a way to validate user input on the fly and have the app refuse to install until any issues are fixed?
For example, lets say I have two numerical inputs from a user, which needs to be 0-99. The second requirement is the second number has to be bigger than the first number.
And if performing this check is possible, how do I feed back to the user what is failing validation?
