Get current index of the visible item #13

Closed brizaldi closed 4 years ago

brizaldi commented 4 years ago

is there a way to get current index of the visible item, for example when the user press the button

rvamsikrishna commented 4 years ago

you already use builder: (BuildContext context, int index) {} to build your list items. Inside this builder using InViewNotifierWidget gives you the bool value whether the widget is in view. Use this bool to add/remove the current index to a List variable.

@brizaldi I am closing the issue as there is no further response. Reopen it if you still have a doubt.
