以下是用法： print(image.getBytes()); var saveImage = await ImageGallerySaver.saveImage( image.getBytes(), name: 'icinvite${index + 1}'); print(saveImage); 看过源码 只有当质量为空或者imageBytes为空才会报错 但是质量是默认的 我打印了image.getBytes() 是有值返回的 image来源是Image库的合成图片代码 ： var bgData = await rootBundle .load('${Constant.ASSETS_IMG}icinvite${index + 1}.png'); var codeData = await rootBundle .load('${Constant.ASSETS_IMG}icon_white.png'); var bg = img.decodeImage(bgData.buffer.asUint8List()); var code = img.decodeImage(codeData.buffer.asUint8List()); if (bg != null && code != null) { var image = img.compositeImage(bg, code, dstX: 105, dstY: 413); 使用的版本是 image_gallery_saver: 2.0.3 [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 255, 128, 191, 4, 255, 180, 193, 58, 255, 178, 192, 106, 253, 178, 191, 143, 254, 177, 191, 183, 255,... 请问应该怎么解决？

去main文件上的AndroidManifest.xml补上这个权限：uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"，自己加上xml的标签</>，大概这样子 < uses-permission.........STORAGE" />
