android - 无法捕获任务“：app：transformClassesWithDexBuilderForDebug”的输出文件指纹

问题描述

我正在尝试使用 Flutter 的墙纸包（https://pub.dartlang.org/packages/wallpaper）创建墙纸应用程序。问题是，当我尝试运行该应用程序时，会出现一个错误，上面写着：

Failed to capture fingerprint of output files for task ':app:transformClassesWithDexBuilderForDebug' property 'streamOutputFolder' during up-to-date check.

这是我尝试访问Wallpaper包功能的 dart 文件的完整代码：

import 'package:flutter/material.dart';
import 'package:wallpaper/wallpaper.dart';

class FullScreenImage extends StatelessWidget {

  String imgPath;
  String imgID;
  FullScreenImage(this.imgPath, this.imgID);

  final LinearGradient backgroundGradient = LinearGradient(
    colors: [Color(0x10000000), Color(0x30000000)],
    begin: Alignment.topLeft,
    end: Alignment.bottomRight,
  );

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SizedBox.expand(
        child: Container(
          decoration: BoxDecoration(
            gradient: backgroundGradient,
          ),
          child: Stack(
            children: <Widget>[
              Align(
                alignment: Alignment.center,
                child: Hero(
                  tag: imgID,
                  child: Image.network(
                    imgPath,
                    fit: BoxFit.cover,
                  ),
                ),
              ),
              Align(
                alignment: Alignment.topCenter,
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.start,
                  mainAxisSize: MainAxisSize.min,
                  children: <Widget>[
                    AppBar(
                      elevation: 8.0,
                      backgroundColor: Colors.transparent,
                      leading: IconButton(
                        icon: Icon(Icons.close),
                        onPressed: () => Navigator.of(context).pop(),
                      ),
                    )
                  ],
                ),
              ),
              Padding(
                padding: EdgeInsets.only(bottom: 4.0),
                child: Align(
                  alignment: Alignment.bottomCenter,
                  child: RaisedButton(
                    color: Colors.transparent,
                    child: Icon(
                      Icons.file_download,
                      color: Colors.white,
                      size: 30,
                    ),
                    onPressed: () async {
                      await Wallpaper.homeScreen(imgPath);
                    },
                  ),
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

我希望该应用程序在 android 的主屏幕上设置壁纸。但是，我收到了一个奇怪的长错误。所以，这是我的控制台日志：
