Help with Firebase database

Hey Koders
Please Help me
I want To add some Automatic feature in my app in that the user get some amount of Points if their Selected Number is equals to the firebase database
I mean
In firebase i have an data
Like
Match Name
17-03-2020
Single=1
Double=2

If this Data Match the user entered data
So User get some point but Now problem is that
I haven’t used any list or other component but its showing error Empty string.

The firebase not getting the Value of the bucket
I can’t explain clearly :sweat_smile:
I will show blocks
And it’s very important

Same Blocks working but after few minutes not working

Do you think strings can only come up with a list view?

Post helpful stuffs.
