PrismRefreshIndicator class

A pull-to-refresh wrapper that works with any scrollable child, not just ListView.

Flutter's RefreshIndicator requires a scrollable child and does not report the state of the refresh, which makes it hard to show a result. This one accepts any child, exposes the state, and gives you a place to show an error or a completion message.

PrismRefreshIndicator(
  onRefresh: () => context.read<NotesCubit>().refresh(),
  child: ListView(children: [...]),
)
