【问题描述】：

当我尝试在模拟器上运行应用程序或在颤振项目上创建 apk 文件时遇到问题。我尝试删除项目，pub get，pub cache clean，deleted flutter folder并重新安装。没有任何帮助，它总是给出以下错误。

/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_form_builder-7.2.1/lib/src/fields/form_builder_date_time_picker.dart:355:7: Error: No named parameter with the name 'anchorPoint'.
      anchorPoint: widget.anchorPoint,
      ^^^^^^^^^^^

【问题讨论】：

您是否已将其发布到 Github 项目 (flutter_form_builder) 问题部分？这将是唯一的方法。
我有同样的错误

标签： flutter android-gradle-plugin flutter-form-builder

【解决方案1】：

您需要将 jdk 添加到环境变量中的 JAVAHOME 路径你可以从这里添加 https://mkyong.com/java/how-to-set-java_home-environment-variable-on-mac-os-x/#what-is-usrlibexecjava-home

解决了这样的问题。我评论了这个小部件中的所有锚点。 /C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_form_builder-7.2.1/lib/src/fields/form_builder_date_time_picker.dart。它对我有用。

【解决方案3】：

我认为flutter_form_builder的最新更新存在一些问题。我通过改变解决了这个问题

  flutter_form_builder: ^7.0.0

到

  flutter_form_builder: 7.0.0

也就是说，我添加的正是7.0.0版本的flutter_form_builder。

如果它也对你有用，谢谢！
