Fix scrollthumb shrinking when vertical padding provided

Open emvaized opened this issue 2 years ago • 1 comments

When vertical padding is provided to the scrollbar, scroll thumb shrinks on reaching the end of scroll. This happens because barMaxScrollExtent doesn't count vertical padding provided to the widget.

My fix changes this behavior by subtracting widget.padding?.vertical in barMaxScrollExtent.

Demonstration with:

DraggableScrollbar.arrows(
        padding: EdgeInsets.only(bottom: 100),
        child: ListView(
        padding: EdgeInsets.only(bottom: 100),
        ...

Before: before (1)

After: after
