indexBarAlignment always centers.

[pcelis19]

indexBarAlignment centers no matter what. So if a user puts Alignment.topRight because of the Container in the build method always applying a center alignment; Alignment.topRight technically becomes Alignment.centerRight.

the line that is causing the problem is:
azlistview/lib/src/index_bar.dart: line 463. Removing this line fixed it for me.

  @override
  Widget build(BuildContext context) {
    return Container(
      color: _isActionDown() ? widget.options.downColor : widget.options.color,
      decoration: _isActionDown()
          ? widget.options.downDecoration
          : widget.options.decoration,
      width: widget.width,
      height: widget.height,
      margin: widget.margin,
      // alignment: Alignment.center, // this line should be deleted
      child: BaseIndexBar(
        data: widget.data,
        width: widget.width,
        itemHeight: widget.itemHeight,
        hapticFeedback: widget.options.hapticFeedback,
        itemBuilder: (BuildContext context, int index) {
          return _buildItem(context, index);
        },
        indexBarDragNotifier: widget.indexBarDragNotifier,
      ),
    );
  }
