Used Library: dart_pdf搜索后,我在GITHUB中发现了相同的问题,但无法解决该问题。我尝试了此操作,但出现了模糊的图像。请帮忙!!

  ByteData data = await rootBundle.load('assets/test.jpg');
  var codec = await instantiateImageCodec(data.buffer.asUint8List());
  var frame = await codec.getNextFrame();

  var imageBytes = await frame.image.toByteData();
  PdfImage assetImage = PdfImage(pdf.document,
      image: imageBytes.buffer.asUint8List(), width: 86, height: 80);

渲染图像:
