Secret About Flutter Material 3 Expressive

Material 3 Expressive Color Schemes

Here at issue 168813

https://github.com/flutter/flutter/issues/168813

We have the leading sentence:

"Currently, we are not actively developing Material 3 Expressive, and we will not be accepting contributions for Expressive features or updates at this time."

That does not mean what you think it means. As to be blunt honest, most of the stuff is there in the SDK or covered in current 3rd party packages. And the widget changes, can be implemented right now, in fact.

In this article I am going to show you some 3rd party packages and how to generate the MX3 (M3E) color schemes that use the expressive on container colors. Also, the implied system to use in making sure that the M3E spec is enforced.
