## What it is
A binding generator that seamlessly connects Flutter/Dart and Rust, generating all glue code so Rust functions can be called from Dart (and vice versa) as if they were native code. It supports arbitrary Rust types, async functions, traits, streams, and one-command project setup.

## Use cases
- call Rust code from a Flutter app
- use Rust libraries in Dart
- build a Flutter mobile app with a Rust backend
- share Rust logic across Flutter platforms
- write performance-critical code in Rust for Flutter
- let Rust call Dart functions
- integrate Rust into an existing Flutter project

## When to choose
- you want high-performance Rust logic inside a Flutter app without hand-writing FFI
- you need arbitrary Rust types, async, traits, or streams across the boundary
- you want a one-liner setup and automatic code generation
- you need bidirectional Rust<->Dart calls

## When to avoid
- your app is pure Dart with no need for Rust
- you target platforms or toolchains outside Flutter/Dart and Rust
- you need a stable ABI for plugins consumed by non-Flutter apps
- you want a minimal hand-rolled FFI with no codegen dependency

## Facets
- artifact type: library
- maturity: stable
- function: sdk, serialization, developer-tools
- domain: cross-platform, mobile-development, developer-tools, web-development
- platform: cross-platform, rust
- tags: ffi, binding-generator, flutter, rust, dart, codegen, interop, mobile, desktop, web-server
