Custom widget import error

[Thomas8607]

Hi,

I have a problem with my custom container. I made a custom keyboard container in my project (4.26.1 compile is ok). I would like use this in another project.
I exported this container which works.

In the another project i import the widget, but compiler get unexpected error.
What is the problem with widget?

Thank you!

The problem was that when I exported the keyboard, there were multiple fonts for the keyboard. I renamed them to TypogrphyKeyboard1 and 2. That way I can import them into another project.
