🚀 Announcing **arithmetic_coder** – a Dart package for arithmetic coding

Hey everyone! 👋

I’ve just published a new Dart package called arithmetic_coder on pub.dev:

🔗 https://pub.dev/packages/arithmetic_coder

What it does

This package provides an implementation of arithmetic coding, a powerful data compression technique that encodes data into compact fractional representations.

Features

• ✅ Adaptive (no pre-trained model required)
• 🧠 Context modeling (order 0, 1, 2)
• ⚡ Efficient O(log n) updates via Fenwick tree
• 📦 Byte-level compression and decompression
• 🔁 Streaming-friendly design
• 🔍 Deterministic decoding with mirrored context state

Feedback, suggestions, and contributions are very welcome 🙏 If you try it out, let me know how it works for you or what could be improved!

Really appreciate your time 💙
