I've been looking into this and it seems like adding a SafeArea widget above the Scrollbar fixes it,

If you update the _totalTrackMainAxisOffsets in ScrollbarPainter to be 0 instead of padding.vertical the issue goes away, the same happens with a ListView with padding: EdgeInsets.zero

Thank you. There is an improvement, but I don't see it completely fixed. Anyway, this seems more like a workaround.

Are there any plans to fix this? Or is there a better solution than adding a SafeArea, which adds additional space above and below the TextField?
