🌍 localized_sorter

High-performance, zero-allocation, linguistic string comparison for Flutter and Dart.

🧐 The Problem

In a global application, standard string sorting (list.sort()) relies on Unicode codepoint values. This creates "alphabetical bugs" where words appear in the wrong order according to a user's native language.

• In Spanish, Niño often appears incorrectly after Oscar because the Unicode value of Ñ is higher than O.
• In Estonian, Zambia appears incorrectly at the end of the list, even though Z is the 19th letter of the alphabet (between S and T).
• In Swedish, Ä is often mixed in with A, despite being a completely distinct letter at the end of the alphabet.

💡 The Solution

localized_sorter solves this by implementing specific Linguistic Rules for 17+ languages.

It is optimized for mobile performance using a Zero-Allocation strategy. Instead of creating new string objects (which triggers Garbage Collection and frame drops), the algorithm uses pointers to compare character codes directly in memory.
