Wrapping up

Congratulations! You have successfully added a Rust component to your Flutter app using flutter_rust_bridge and configured flutter run (more on web later) to build your Rust library and link it to the app.

As a reminder, you need to run these commands every time your Rust code changes and before you run flutter run:

{{#include command.sh.txt}}

Renaming the Rust bridge module

If you would like to use the --rust-output flag of flutter_rust_bridge_codegen, keep in mind that you will have to update $crate/src/lib.rs to point to the correct file, for example if you use this command instead:

flutter_rust_bridge_codegen \
    ..
    --rust-output $crate/src/my_bridge.rs

then you need to modify this in lib.rs:

- mod bridge_generated;
+ mod my_bridge;

flutter_rust_bridge_serve-less workflows

If you don't need to run Flutter Web in development mode and would rather build in release mode once in a while, read here for instructions on how to build your WASM binary without flutter_rust_bridge_serve.
