"The named parameter keyboardDismissBehavior isn't defined" 没有 pull_to_refresh

Question

如题，我收到一条错误信息，说singleChildScrollView没有keyboardDismissBehavior 属性。有文章说这个问题是pull_to_refresh包的版本问题。但是我没有在我的项目中使用那个包。请帮忙。

根据Flutter docs，keyboardDismissBehavior参数仅在v2.2.0之后的Flutter中可用：

76312 add keyboardDismissBehavior into SingleChildScrollView (cla: yes, f: scrolling, framework, waiting for tree to go green)

要解决此问题，只需 upgrade your Flutter:

flutter upgrade
