pasteboard.image: when system clipboard content changed, then it will crash

It is OK to get the image when there is image content in the system clipboard, but when I change the content, like I make another screenshot, then I cannot get the updated image, and it will crash my app.

Please help to check and solve it.

Thanks a lot!

Below is my code which is used together with Flutter_quill

Future _handlePasteImage() async {
try {
Uint8List? imageBytes = await Pasteboard.image;

  if (imageBytes == null || imageBytes.isEmpty) {
    debugPrint("no valid pic");
    return;
  }

  
  final decodedImage = await decodeImageFromList(imageBytes);
  if (decodedImage.width <= 0 || decodedImage.height <= 0) {
    debugPrint("no valid pic");
    return;
  }


  final dir = await getApplicationDocumentsDirectory();
  final fileName = 'pasted_${DateTime.now().millisecondsSinceEpoch}.png';
  final file = File('${dir.path}/$fileName');

  await file.writeAsBytes(imageBytes); 
  debugPrint("saved: ${file.path}");


  final imageUrl = file.path;
  final selection = Get.find<NoteViewController>().quill_controller.selection;
  final index = selection.baseOffset < 0 ? 0 : selection.baseOffset;

  Get.find<NoteViewController>().quill_controller.document.insert(index, BlockEmbed.image(imageUrl));
  Get.find<NoteViewController>().quill_controller.updateSelection(
    TextSelection.collapsed(offset: index + 1),
    ChangeSource.local,
  );
} catch (e, stack) {
  debugPrint("error: $e");
  debugPrint("$stack");
  if (mounted) {
    ScaffoldMessenger.of(context).showSnackBar(
      const SnackBar(content: Text("error")),
    );
  }
}

}

Start by reproducing the failure through the Pasteboard.image entry point after replacing the system clipboard image with another screenshot. Inspect the plugin's clipboard image handling and verify that the updated image can be retrieved without crashing the Flutter app.
