当我尝试构建APK时，调试控制台中显示以下内容。生成失败，出现异常。
控制台中的错误：

"PictureStreamCompleter"来自"package：flutter_svg/src/picture_stream. dart"（'/C：/src/flutter/flutter/. pub-cache/hosted/pub.dartlang. org/flutter_svg-0.17.4/lib/src/picture_stream. dart'）。请尝试将名称更正为现有方法的名称，或定义一个名为"toStringShort"的方法。如果存在：_completer？. toStringShort（），^^^^^^^^^^^^/C：/src/flutter/flutter/. pub-cache/hosted/www.example.com错误：超类没有名为"调试填充属性"的方法。pub.dartlang.org/flutter_svg-0.17.4/lib/src/picture_stream.dart:266:11: Error: Superclass has no method named 'debugFillProperties'. super.debugFillProperties(description); ^^^^^^^^^^^^^^^^^^^

失败：生成失败，出现异常。

其中：脚本"C：\src\flutter\flutter\packages\flutter_tools\gradle\flutter. gradle"行：896
出了什么问题：任务"：app：compileFlutterBuildDebug"的执行失败。

进程"命令" C：\src\flutter\flutter\bin\flutter.bat "已完成，退出值为非零值1

尝试：使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获取更多日志输出。使用--scan运行以获取完整的见解。

我也遇到了和你一样的错误，我的解决方案是把flutter_svg包更新到最新版本，所以我建议你进入你的pubspec.yaml，在dependencies下做以下事情：

flutter_svg: 0.18.0

然后运行pub get，希望错误会消失。

To change dependency:

 flutter_svg: ^0.17.4  to flutter_svg: ^0.18.0

然后，

flutter pub get
flutter clean

然后，运行

为了解决这个问题，在pubspec.yaml中进行了以下更新

Flutter_svg: ^0.18.0
flutter_html: ^1.0.2
flutter_widget_from_html: 0.4.3

这三个依赖项导致的大多数错误
