Useful or not, from you.
flutter NoSuchMethodError: Class 'QuerySnapshot' has no instance getter 'length'

The error appears when I try to access '' to generate a GridView. children: List.generate(, (index) { This was all working about 12 hours from now, but today after a few app-runs it started to shout out this error. Similarly, I cannot access '[index]' now, the error is similar to the above mentioned.

That's a useful answer
Without any help

why was this closed? i ran into this today, what was the resolution?
