  stream: controller.stream,
  builder: (context, snapshot) {
    if (snapshot.hasData) {
      return AsciiImageWidget(
        ascii: AsciiImage.fromSimpleString(snapshot.data!),

    }
    return CircularProgressIndicator();
  },

// Control flash
await controller.flashOn();
await controller.flashOff();
await controller.flashAuto();
