Introducing Chroma Theme 🎨

A Premium Material 3 Dynamic Theming Engine for Flutter

Managing themes in Flutter can become complex very quickly, especially when working with Material 3.

You often need to:

• Configure dozens of colors
• Support Light and Dark themes
• Add AMOLED and High Contrast modes
• Manage custom palettes
• Persist user preferences
• Write repetitive ThemeData boilerplate

To solve this, I built Chroma Theme.

Chroma Theme is a premium, dynamic, and adaptive Material 3 theming engine for Flutter that turns a single seed color into a complete, production-ready theme system.

✨ Features

• 🎨 Dynamic seed-based color generation
• 🌗 Light, Dark, AMOLED, and High Contrast modes
• 🎭 20+ professionally curated palettes
• 🛠️ Full Material 3 tonal palette access
• 🧩 Global component overrides
• 💾 Theme persistence support
• 🚀 Intuitive BuildContext extensions
• ♿ Accessibility-focused design
