flutter_rust_bridge VS rust-android-gradle

Use some sort of executable file, like webassembly. I've seen extism which is really cool. Though theres no dart port for it or a dart package, i think something could be done via flutter_rust_brige. This will allow people to use the languages supported via extism (js, go, rust, zig, cpp etc) to their full potential and have the language's ecosystem available and they can just compile the plugin to a wasm file and use it in the app. Downsides would be ig using that rust package in dart since flutter_rust_bridge does have some amount of complexity. And that for example, two plugins both written in say for example js, depend on some sort of http package, and both plugins load the same package twice in their respective wasm files. ig plugin files would be more larger in the end.

Not a Flutter Dev, but have you tried 'flutter_rust_bridge' [0]. Seems provide some interop between flutter and rust and looks like a popular and active project. I'm native mobile dev and just curious about this kind of interop myself. If it's seamless then looks like good balance to do mobile front-end in flutter and mobile backend in rust.

This template is primarily built using the flutter_rust_bridge library. It also incorporates several popular packages and modifications into the default Flutter template, ensuring optimal development process. It has been designed with future scalability and performance in mind.

If you want example code, the flutter_rust_bridge uses a webworker pool with shared memory on the web to multithread the execution.

There's also the thing that flutter_rust_bridge is currently broken for web development. I have a PR open, but it's running into weird issues with the CI and so can't be merged.

For reference, https://github.com/fzyzcjy/flutter_rust_bridge. And dart is a really nice language too, my only real gripe is that I'm no longer used to [type] [variable] over [variable]: [type]

It appears that this is indeed what was happening. The issue has now been fixed in the template.

I thought for a second you meant physical rust... Anyway, rust doesn't have any benefits in FTC. If you really needed to use it you could try to use this but you still won't have any way of using the FTC SDK as it was built for java(at least without porting it to rust which will be a ton of work).

Is there any easy way to do this? I've seen this plugin as well, but it looks pretty much the same

That's significantly better than the C world where each project comes bundled with a bespoke build system that nobody else uses. I'm also not convinced that cargo present a significant barrier to interop. There's a Rust plugin for gradle (https://github.com/mozilla/rust-android-gradle) which bridges between gradle and Cargo. Looks simple enough to me.

rust-android-gradle to hook cargo into Android Gradle project

This works great for android https://github.com/mozilla/rust-android-gradle

The mozilla gradle plugin makes compiling and packaging rust libraries quite painless. The jni-crate can be used on Android as well.
