Supercharging Your Flutter Apps with Rust
summary
Shows how to call Rust from Flutter using Flutter Rust Bridge to generate FFI bindings and async, zero‑copy calls that avoid blocking the UI. Demonstrates a working app that records audio in Flutter, sends it through Rust bindings to whisper.cpp, and returns text in about 860 ms on an M1 (under 1s on an iPhone 12). Notes real setup pain points: per‑platform linking (static libs, dylibs, NDK), FFmpeg audio conversion, and CUDA dependency for GPU inference.
