Question

我以前的项目中，我使用了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。

没有冲洗工具的情况下，项目运行良好。

完整的错误消息

我尝试了这四个版本，但没有变化

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

我也曾经用过

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

升级后，我也面临着同样的问题。现在从您的pubspec.yaml中删除^。应该可以。

 flushbar: 1.5.3
