Divider Hides Edges of view1 and view2

[cedarbob]

The Positioned widgets which wrap view1 and view2 each need to have one of their left, right, bottom or top fields adjusted to account for the widget.gripSize. For example, in a horizontal SplitView, the Positioned widget which wraps view1 should probably have its right field set to widget.gripSize / 2.0.

@cedarbob Thank you for your advice. I'll fix it.

The fix just made didn't solve the issue. Below is the fix I had in mind for _buildHorizontalView (in my original post I meant to say 'increase the right field by widget.gripSize / 2.0', instead of 'set to widget.gripSize / 2.0):

  Widget _buildHorizontalView(BuildContext context, BoxConstraints constraints, double w) {
    final double left = constraints.maxWidth * w;
    final double right = constraints.maxWidth * (1.0 - w);

    return Stack(
      children: <Widget>[
        Positioned(
          top: 0,
          left: 0,
          right: right + widget.gripSize / 2.0,
          bottom: 0,
          child: widget.view1,
        ),
        Positioned(
          top: 0,
          left: left + widget.gripSize / 2.0,
          right: 0,
          bottom: 0,
          child: widget.view2,
        ),
        Positioned(
          top: 0,
          left: left - widget.gripSize / 2.0,
          right: right - widget.gripSize / 2.0,
          bottom: 0,
          child: MouseRegion(
            cursor: SystemMouseCursors.resizeColumn,
            child: GestureDetector(
              behavior: HitTestBehavior.translucent,
              onVerticalDragUpdate: (detail) {
                final RenderBox container = context.findRenderObject() as RenderBox;
                final pos = container.globalToLocal(detail.globalPosition);
                if (pos.dx > widget.positionLimit &&
                    pos.dx < (container.size.width - widget.positionLimit)) {
                  weight.value = pos.dx / container.size.width;
                }
              },
              child: Container(color: widget.gripColor),
            ),
          ),
        ),
      ],
    );
  }

@cedarbob Thank you for your report. I couldn't find the bug because the sample project wasn't built correctly. I fixed it. Is it in line with your idea?

[cedarbob]

Reran my tests and the latest update works great.
