Can someone tell me how to auto refresh a screen? i am getting data from firebase and it is updating every second. I need to make it auto refresh screen every second to make it realtime.

Use a timer
when Clock1.Timer
call FirebaseDB1.getValue
tag = <whatever you wish to>
valueIfTagNotThere = ""

Then use
when FirebaseDB1.gotValue
if tag = <whatever you wish to>
set label1.text = get value
