followed the ful tutorial but i am getting this error about clima-flutter-completed HOT 1 OPEN

'package:flutter/src/widgets/text.dart':
Failed assertion: line 360 pos 10: 'data != null'

error is at:
'package:flutter/src/widgets/text.dart':
Failed assertion: line 360 pos 10: 'data != null'

this widget is getting null data, and error being thrown from constructor of the text widget. Pls check if you can figure out, otherwise you need to share that code file. i will load my project next week but i made many changes so it might not be same as the one we have on tutorial. Let me know i can send you a particular file.

}) : assert(
data != null,
'A non-null String must be provided to a Text widget.',
),
