FlutterZebraIntegration class

High-level API for communicating with a Zebra ZPL label printer over WiFi.

Instantiate once and keep alive for the lifetime of the feature that needs printer access. Call dispose when finished to release the connection status stream.

class _MyWidgetState extends State<MyWidget> {
  final _zebra = FlutterZebraIntegration();

  @override
  void dispose() {
    _zebra.dispose();
    super.dispose();
  }
}
