getMaxChildIndexForScrollOffset method
- @override
override
The maximum child index that is visible at the given scroll offset.
This function is given the itemExtent as an argument to avoid
recomputing itemExtent repeatedly during layout.
By default, returns a value consistent with the children being placed in order, without gaps, starting from layout offset zero.
Implementation
@override
int getMaxChildIndexForScrollOffset(double scrollOffset, double itemExtent) {
return super.getMaxChildIndexForScrollOffset(math.max(scrollOffset - _padding, 0.0), itemExtent);
}
