Remaining roadmap: Adding gradient functionality, blend modes, GLSL shader

[Zabadam]

There was a note in the HCT blog post on material.io about gradient functionality as well as a mention in this project's README: "Color interpolation in HCT ... Harmonizing, animations, gradients [using Blend]."

Is this a manual affair? Were there (perhaps scrapped) plans to still add features in the Blend topic?

Surely I can create my own Gradient subclass in Flutter that lerps utilizing Blend.hctHue, but I did not want to spend that time if this package still has a roadmap.

The other features mentioned in that blog all sound exciting, too, like legible text on any background, filters and blend modes, and the GLSL shader.
