From Flutter & Rust to Pure Rust: A Case Study in Simplifying AI App Development

The developer of a small AI application, BoquilaHUB, shares their experience transitioning from a Flutter/Rust architecture to a pure Rust application using egui. Initially using flutter_rust_bridge to connect a Flutter UI with a Rust backend, the developer encountered frustration with code generation overhead, FFI complexities, and the challenges of designing a cross-language API. Switching to egui, a Rust-based GUI library, and rewriting the UI over a weekend proved transformative. The pure Rust approach simplified project complexity, improved code readability and maintainability, and yielded significant performance gains. The developer highlights egui's ease of use in eliminating common Flutter UI refresh issues and complex state management, resulting in a faster and more responsive application.
