颤动运行问题错误：没有名为“anchorPoint”的命名参数

Question

当我试图在模拟器上运行应用程序时，或者在flutter项目上创建apk文件时，我面临着这个问题。我尝试删除项目、pub-get、pub-cache-clean、删除flutter文件夹并重新安装。没有什么帮助，它总是给出下面的错误。

/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,
      ^^^^^^^^^^^
/C:/src/flutter/packages/flutter/lib/src/material/date_picker.dart:133:19: Context: Found this candidate, but the arguments don't match.
Future<DateTime?> showDatePicker({
                  ^^^^^^^^^^^^^^

Answer 1

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

您需要将jdk添加到环境中的JAVAHOME路径，您可以从此处添加它 https://mkyong.com/java/how-to-set-java_home-environment-variable-on-mac-os-x/#what-is-usrlibexecjava-home

你可以在这里找到你的问题的解决方案，在Flutter上找不到捆绑的Java版本

我认为flutter_form_builder的最新更新存在一些问题。我通过更改解决了问题

  flutter_form_builder: ^7.0.0

到

  flutter_form_builder: 7.0.0

换句话说，我添加了flatter_form_builder的7.0.0版本。

谢谢我，如果它对你也有效！
