Bro why aren't u replying for the error that document does not exists in querysnapshot

[kaivalyasinha]

i had taken your code from Github and tried to use it. I have connected the android part of the app to firebase. Now that I run it, it is showing Platform exception at line 42 in create_blog.dart. basically it shows that User does not have access to this object once I upload a blog. Also whenever I start the app from scratch, the app shows an error that the getter documents was called on null - NoSuchMethodError.


Please do help, I am also going through your videos for reference.


Thank you!

Mr Tiwari thank you a lot for this tutorial, for your effort and your teachings. I have a situation in the debug I wonder if others have the same error as I do:
Performing hot reload...
Syncing files to device iPhone 11 Pro Max...


"
════════ Exception caught by widgets library
The following assertion was thrown building BlogsTile(dirty, dependencies: [MediaQuery]):
Failed assertion: line 163 pos 16: 'imageUrl != null': is not true.

The relevant error-causing widget was:
When the exception was thrown, this was the stack:
#2 new CachedNetworkImage
#3 BlogsTile.build
#4 StatelessElement.build
#5
#6 Element.rebuild

Any idea?

I've been struggling with this error for a long time. I'd be glad if you can help me.

Code:
