Utility package that provides a seamless way to use box widgets sandwiched between slivers

Features

1. Two widgets: SliverPassthrough and BoxToSliverPassthrough. First one turns sliver layout protocol to a box one, and the second one continues sliver layout where the first left off.
2. SliverPassthrough also provides boxScrollOffset in the form of ValueListenable<double>, which can be useful for CustomPaint, for example.

Usage

CustomScrollView(
  slivers: [
    SliverPassthrough( // sliver
      minBoxExtent: .0, // extends scroll extent and prevents the box from squishing to 0, if necessary
      child: ColoredBox( // box
        color: Colors.red,
        child: BoxToSliverPassthrough(
          sliver: SliverList( // sliver again, scrolled by the original CustomScrollView
            delegate: SliverChildBuilderDelegate(
              (context, index) => SizedBox(),
            ),
          ),
        )
      ),
    ),
  ],
)
