Flushbar plugin: Error: The method 'attach' isn't defined for the class 'FocusScopeNode'

Question

我之前的项目我使用flushbar插件没有任何错误。但是我的新项目在尝试使用 flushbar 时出现错误..

项目在没有 flushbar 的情况下运行良好。

这四个版本我都试过了，没啥变化

  flushbar: ^1.3.0
  flushbar: ^1.5.3
  flushbar: ^1.7.0
  flushbar: ^1.6.0

我也用过，

  FocusScope.of(context).requestFocus(FocusNode()),

Answer 1

flutter升级后我遇到了同样的问题。暂时从 pubspec.yaml 中删除 ^ 。它应该可以工作。

 flushbar: 1.5.3
