错误：使用 pdftron 在 flutter 中构建 Android 应用程序时找不到符号

Question

我正在尝试使用依赖项https://pub.dev/packages/pdftron_flutter pdf tron 在flutter应用程序中显示pdf文件，当我尝试构建android应用程序时，我收到错误

     C:\Users\USER\AppData\Local\Pub\Cache\hosted\pub.dev\pdftron_flutter-1.0.1-      32\android\src\main\java\com\pdftron\pdftronflutter\helpers\PluginUtils.java:987: error: cannot       find symbol stringRes != R.string.document_save_error_toast_message; ^ symbol:   variable string location: class R

这是 flutter doctor 的输出

我尝试实现链接中的所有解决方案“错误：找不到符号”在flutter中构建Android时

就像运行

flutter clean

并将

compileSdkVersion, minSdkVersion targetSdkVersion

分别更改为 34,21,34 但它不起作用

此问题已通过将 Gradle 降级到 7.3.0 得到解决
