How to export the theme structure and providers?

[xypnox]

I am creating a small utility package that will contain all the styled-component themes with custom structure and a provider.

I have been able to set it up with a provider and I do get the values of theme when using in an external react app using the package.

The problem is with exporting the types of the structured theme, I need to use the same styled.d.ts definition of the theme in the utility package and the external app.

I don't want to copy paste and maintain the styled.d.ts manually between the projects.

Is there a way to share the types of the theme across the packages?
