Dart Use a setter for operations that conceptually change a property
I guess it wants you to do:
set scrollToPosition(int selectedPagePosition) { position.value = selectedPagePosition;}and then callers would use scrollToPosition = position instead of scrollToPosition(position).
Assuming that scrollToPosition() performs some scrolling action, personally I prefer it looking like a function call, and I'd suppress the lint with
// ignore: use_setters_to_change_properties(However, if it were named position, a setter might be more fitting.)
