 OutlinedButton(
                        child: Text('print receipt(esc)'),
                        onPressed: _connected
                            ? () async {
                                Map<String, dynamic> config = Map();
                                List<LineText> list = [];

                                list.add(LineText(
                                  type: LineText.TYPE_TEXT,
                                  content: 'hi this is a test',
                                  weight: 1,
                                  align: LineText.ALIGN_CENTER,
                                ));
                        
                                ByteData data = await rootBundle
                                    .load("assets/images/bluetooth_print.png");
                                List<int> imageBytes = data.buffer.asUint8List(
                                    data.offsetInBytes, data.lengthInBytes);
                                String base64Image = base64Encode(imageBytes);
                                list.add(LineText(
                                    type: LineText.TYPE_IMAGE,
                                    content: base64Image,
                                    align: LineText.ALIGN_CENTER,
                                    linefeed: 1));
                                await bluetoothPrint.printReceipt(config, list);
                              }
                            : null,
                      ),

hi i was facing the same error i resolved by adding height and width

list2.add(LineText(type: LineText.TYPE_IMAGE, content: base64Image, height: 90, width: 90, align: LineText.ALIGN_CENTER,));

Don't work in my case 😔 . I have the next code:

ByteData data = await rootBundle.load(ImageUtils.getImagePath("logo_ticket.png"));
List<int> imageBytes = data.buffer.asUint8List(data.offsetInBytes, data.lengthInBytes);
String base64Image = base64Encode(imageBytes);

    header.add(LineText(
        type: LineText.TYPE_IMAGE,
        height: 350,
        width: 350,
        content: base64Image,
        align: LineText.ALIGN_CENTER));

hi, try first to comment everything else and see if the image is printing. if it doesn't try to debug by setting break point before print or print in the console base64Image and see if there actually image to print.

Thanks

try this one its worked for me. 
 List<LineText> list1 = [];
    ByteData data =
        await rootBundle.load("assets/static_images/ic-hmc-black.png");
    List<int> imageBytes =
        data.buffer.asUint8List(data.offsetInBytes, data.lengthInBytes);
    String base64Image = base64Encode(imageBytes);
    list1.add(LineText(
      type: LineText.TYPE_IMAGE,
      x: 10,
      y: 10,
      height: 200,
      width: 200,
      content: base64Image,
    ),
);

@Zia9335 Its working but position not start exactly to next label once first label done printing. Setting correct width and height with gap in labell configuration.
