Additional context

From the error message we can see something wrong with showcaseview overlay, but I can't find ways to solve it. (I have searched on google and stackoverflow, but no results.

I closely followed the example code and also searched on other use case to apply this plugin, my code is similar like this one: https://stackoverflow.com/questions/60930636/how-can-i-use-show-case-view-in-flutter

The plugin is working (although it's not working as I expected, that can be feature suggestions, but as least it's working as the example shows). However I always get this error complain every time I start or hot reload.

When I remove all the code related with this plugin, I don't get any error complain, so it's definitely the plugin issue.

How can I solve this? does any of other people get same error like i do? is it something wrong with the plugin? thank you!

I am using the latest version of flutter and the plugin, every thing's version is the latest, I always upgrade as soon as I can.
