Some callback needed

[sm2017]

@naqvitalha I want to implement a simple version of sticky header for my use case
How can I detect that which item is topmost (or bottommost) and which is coming in view report and which is go out?

Check out the onVisibleIndexesChanged callback for the same. You can infer most of what you want from the callback. RecyclerListView.js proptype definitely is a good place to explore all features.
