## What it is
Rinf is a framework that combines Rust for native business logic with Flutter for the GUI, communicating via native FFI with type-safe generated message classes. It supports all Flutter platforms including Linux, Android, Windows, macOS, iOS, and Web.

## Use cases
- build a cross-platform app with Rust backend and Flutter UI
- write business logic in Rust for a mobile app
- use native FFI instead of webviews to connect Rust and Dart
- share Rust code across Android, iOS, and desktop apps
- stream typed messages from Rust to Flutter widgets
- avoid running a web server inside a mobile app

## When to choose
- you want Rust performance for app logic with a polished Flutter UI
- you need one codebase targeting mobile, desktop, and web
- you want type-safe Dart-Rust communication without webviews or HTTP overhead
- you prefer native FFI over embedding a web server in your app

## When to avoid
- your app is pure Dart/Flutter with no need for Rust
- you need a framework with active dedicated maintenance (project is seeking a new maintainer)
- you target embedded Linux as a primary platform (only experimental)
- you want a pure Rust GUI without Flutter

## Facets
- artifact type: framework
- maturity: maintenance
- function: gui, mobile-framework, sdk, serialization, concurrency
- domain: cross-platform, mobile-development, desktop-applications, web-development, developer-tools
- platform: windows, cross-platform, rust
- tags: flutter, ffi, rust-bindings, dart-codegen, type-safe-messaging, cross-platform-apps, android, ios, linux, macos, web-server
