Repository Update: Mix Ecosystem Reorganization
We’ve made an architectural decision to reorganize the Mix ecosystem for better clarity, scalability, and maintenance.
Remix and Naked have been moved to separate repositories, allowing them to evolve independently as standalone design system layers.
The Mix repository will continue to host:
Mix 1.7.0 - mix Release Notes | AnnounceHQ
mix (core)
mix_lint
mix_generator
mix_annotations This structure keeps the core styling engine unified, while encouraging modular growth across the ecosystem.
Introducing ComputedStyle: Smarter, Faster Widget Rebuilds in Mix This update brings a breakthrough performance improvement to the Mix framework:
ComputedStyle and ComputedStyleProvider – a new system that rebuilds only what’s needed, using InheritedModel under the hood.
🚀 What it solves: Traditional rebuilds could affect entire widget subtrees. With ComputedStyle, we now get:
• Up to 70% fewer unnecessary rebuilds
• O(1) style resolution
This change makes Mix significantly more scalable for large apps.
Cleaner Style API: No More .chain We’ve simplified the way you write styles in Mix.
You no longer need .chain to compose multiple style elements. 🎉
👇 Before:
Style(
$box.chain
..padding.all(12)
..color.red()
..border.all.color.redAccent(),
)
Style(
$box
..padding.all(12)
..color.red()
..border.all.color.redAccent(),
)
This is part of our ongoing effort to make Mix more intuitive, predictable, and joyful to use.
