Flutter has come a long way making cross-platform development truly accessible but there are still some areas that Flutter and Dart struggle to handle, and that’s where dart FFI with Rust comes in. Recently, while looking for a mermaid diagram rendering in Flutter, after not finding any good Flutter libs, I used Flutter-Rust bridge that allowed me to achieve what I wanted and results were astounding. This allowed me to do some amazing things.

This talk explores using Rust to enhance Flutter’s cross-platform support. It can not only improve computational times for heavier tasks but also give access to low-level apis that allows better integration with the platform.

We’ll explore how dart FFI makes the Flutter-Rust bridge possible, and understand how Flutter and Rust communicate. You’ll learn to create ur own Flutter-Rust lib while learning from real world use cases. You’ll definitely leave this talk being curious about Rust and understanding when, why and how to use Rust in Flutter.
