Printing only one image when trying to print list of images in a loop.

[Asim-9812]

I have been trying to print a list of images in a loop but it only print once. I tried printing text in place of the images it works as intended but cannot print the images.

class _PrintPreview extends StatefulWidget {
  final int count;
  final List<Uint8List> imageList;

  _PrintPreview({required this.count, required this.imageList});

  @override
  _PrintPreviewState createState() => _PrintPreviewState();
}

class _PrintPreviewState extends State<_PrintPreview> {
  @override
  void initState() {
    super.initState();
    _bindingPrinter();
  }

  /// Must bind your printer at first init in the app
  Future<bool?> _bindingPrinter() async {
    final bool? result = await SunmiPrinter.bindingPrinter();
    return result;
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Print Preview'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(8.0),
        child: Column(
          children: [
            Expanded(
              child: SingleChildScrollView(
                scrollDirection: Axis.horizontal,
                child: Row(
                  children: List.generate(widget.count, (index) {
                    return Padding(
                      padding: const EdgeInsets.all(8.0),
                      child: Image.memory(widget.imageList[index]),
                    );
                  }),
                ),
              ),
            ),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: () async {
                await SunmiPrinter.initPrinter();
                await SunmiPrinter.startTransactionPrint(true);

                  for (int i = 0; i<widget.imageList.length; i++) {
                    await SunmiPrinter.printImage(widget.imageList[i]);

                  }
                await SunmiPrinter.exitTransactionPrint(false);


                // await SunmiPrinter.exitTransactionPrint(true);
              },
              child: Text('Print'),
            ),
          ],
        ),
      ),
    );
  }
}

Can you try to put in the loop the start and finish process inside your loop? In my example i print 2 images , from web and from assets, can you run to try?
