The reason for the error in post 1 is, you have failed to add On which compinent you are trying to create recycle view… You must use that create component in OnCreateviewHolder… Kodular recycler view is different… Where yoy will initialise with on which component you are going to create but here in niotron default block, you must add the createcomponet must be added mannualy
In post2 you have added that function block so it was successful
