This is what i get when i scroll to the bottom

java.lang.IllegalArgumentException: Inconsistency between the count of nodes tracked by the state (0) and the children count on the SubcomposeLayout (1). Are you trying to use the state of the disposed SubcomposeLayout?

@ma-za-kpe I copied and pasted the code above and worked fine for me... Did you make any change on it?

Hello, so I'm trying to load this https://raw.githubusercontent.com/DevTides/DogsApi/master/dogs.json data into the row. And that's the error I got.

It scrolls fine till the bottom, but at the very end crashes

Ive revereted to using this, val wishlisted = (1..50).map { "Wishlisted Book $it" }
, in the second grid view ... It crushes every time... with the same error

It's not happening here... Which compose version you're using? I'm using 1.2.0-alpha07, but I don't think it's related to the version...

Oh man!

@ma-za-kpe I implemented your sample accessing the JSON file... it's working for me.
You can see the code in the links below...

Thank you for this...let me give it a go.

FYI: I was able to reproduce your issue when I tried to update my project to the latest version of compose and accompanist (1.2.0-alpha08 and 0.24.7-alpha respectively)
Check here: google/accompanist#1140
I reverted this change and it worked.
