NetworkBuilder class

A widget that rebuilds whenever NetworkManager emits a new state.

NetworkBuilder(
  manager: networkManager,
  builder: (context, state) {
    return switch (state) {
      Idle()    => Text('Ready'),
      Loading() => CircularProgressIndicator(),
      Offline() => OfflineBanner(queued: state.queuedRequests),
      Syncing() => LinearProgressIndicator(value: state.progress),
      Success() => DataView(data: state.data),
      Error()   => ErrorView(message: state.message),
    };
  },
)
