[Feature Request] Add AI support to Theme Playground

[Dev-Salem]

Problem

Right now, we rely on the pre-defined themes in Flex Color Scheme, or we risk manually modifying one of them to match the brand identity of our apps. While these themes are a solid starting point, we often need to adjust seed colors and configure numerous widget properties to achieve a platform-agnostic look. Most developers are not fully familiar with all the Material Design properties or how they affect the overall appearance of an app. The Theme Playground helps, but there’s still noticeable friction.

Proposal

Integrate an AI-powered chat assistant into the Playground that can take user requirements and generate a custom theme automatically—similar to what tweakcn offers (screenshot attached). While it’s possible to ask an AI in an IDE to build a custom theme, these attempts usually fail because the models aren’t specialized in Flex Color Scheme and lack awareness of all the relevant properties.
