In my cloud DB got value block, it always gets and im not sure why.

This is part of a chat app that im making, and this is a code system, so that users can enter and create new chats

I don't understand your code.

  • Where does start value get its value?
  • All you ever store in CloudDB is blank or an empty text?

  1. if its screen1, it can't get start value and it returns null

  2. nothing is stored on call cloud DB store value and it returns null

  3. I don't know show me your screen numbers and more information

I advice start from a simple chat app using cloud DB or a simple chat app using bluetooth, this should help you to make your own chat app

  1. This is not screen 1, it goes from screen 1 to this screen.
  2. No, i just wanted to store that because I need to save that later to check if its already taken
    If you want, I can send you the file
