I just began learning Kotlin for work and one of the first errors I encountered is “overrides nothing” pointing at the overrides of the function instantiateItem() for my PagerAdapter
The function/method signature was like this:
override fun instantiateItem(parent: ViewGroup?, position: Int): Any {
To fix the error, I simply removed the question mark from the arguments so that it looked like:
override fun instantiateItem(parent: ViewGroup, position: Int): Any {
Voila! Error gone and the swipe view that needed the PagerAdapter worked.
Reference: Sudden “overrides nothing” errors appear, no recent change to Kotlin build version
