Pinned tab bar without external packages. It's just Slivers.
#Flutter
Yes no pkg needed for this, the slivers can do it just fine. APIs are a bit verbose and Sliver naming sounds scary.
I am using it like this for
@chargespot_app
Container(
child: CustomScrollView(
slivers: [
SliverAppBar(),
SliverToBoxAdapter(),
SliverAppBar(),
SliverList.list(children: []),
])
