我正在尝试将带有链接的assetImage（“assets/image.png”）转换为文件/uint 8List/

final ByteData byteData = await rootBundle.load(logoUrl);
final File assetLogoFile =
File("${(await getTemporaryDirectory()).path}/$logoUrl");

File markerLogoFile = await assetLogoFile.writeAsBytes(byteData.buffer
        .asUint8List(byteData.offsetInBytes, byteData.lengthInBytes));

final Uint8List logoUint8List = await markerLogoFile.readAsBytes();

我收到以下错误;

E/flutter ( 5136): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: FileSystemException: Cannot open file, path = '/data/user/0/com.example.project/cache/assets/images/flare.png' (OS Error: No such file or directory, errno = 2)
