access to RouteAwareStateMixin ?

[vptcnt]

Describe the bug

Hello,

Is it possible to have access to the mixin RouteAwareStateMixin ? and the others ones ?
The methods didPush, didPop, didChangeTapRoute,... will be working ?

If I try to import the mixin, I do receive a warning :

Import of a library in the 'lib/src' directory of another package.
Try importing a public library that exports this library, or removing the import.

What operating system do you use?

macOS
