PrismViewState<T> class sealed

A sealed view-state that drives PrismStateView rendering.

Dart 3 exhaustive switching means the compiler forces you to handle every state — no more forgotten error branches:

final state = switch (fetch()) {
  PrismViewLoading() => const CircularProgressIndicator(),
  PrismViewError(:final error) => Text('Failed: $error'),
  PrismViewEmpty() => const Text('Nothing here yet'),
  PrismViewSuccess(:final data) => Text(data),
};
