Request for Official Support for Golang and Rust Interoperability in Dart

[stephane-archer]

The Dart language currently supports interoperability with C, Swift, Kotlin, and JavaScript, as detailed in the official documentation. However, there is no mention of official support for two increasingly popular and performance-focused languages: Golang and Rust.

Given the widespread adoption of Golang and Rust in systems programming and server-side development, adding official support for these languages could greatly enhance Dart's ecosystem. Both languages are known for their efficiency and strong community backing, making them valuable complements to Dart's existing capabilities.

Official support for Golang and Rust interop would solidify Dart's position as a modern, versatile language capable of bridging the gap between high-level application development and low-level systems programming. Can we hope to see this added to the roadmap?

Summary: User requests official Dart support for interoperability with Go and Rust, citing their popularity and performance benefits for expanding Dart's capabilities.

Rust interop is already supported by a 3rd party package: https://pub.dev/packages/flutter_rust_bridge

I think @dcharkes investigated the possibility of Golang interop for a GSoC project. We don't really have the resources to put the same time and effort into Go interop that we do into C/ObjC/Java etc. But there's nothing stopping the community from building a Go version of flutter_rust_bridge.

Can we hope for a simple page like this one for Rust? https://dart.dev/interop/c-interop
I feel this can easily go under the radar because there is no mention of Rust in the official documentation (it did for me).
C++ is just mentioned here: https://docs.flutter.dev/platform-integration/platform-channels , no idea if it's just the c-interop or if it is a deeper interop
looking at that page:

Kotlin or Java on Android
Swift or Objective-C on iOS
C++ on Windows
Objective-C on macOS
C on Linux

This is not accurate, macOS supports Swift too. I can't imagine C be only available for Linux only...
I would love it if we can make the interop doc a bit more accurate and complete

I'm glad to hear @dcharkes is working on Golang interop, the easy parallelism of this language without the complexity of Rust would be great.

+1 to what @liamappelbe said. Rust and Go are community efforts. 👍

For Go there's also a project started already: https://github.com/csnewman/flutter-go-bridge I'm @csnewman would be happy with contributions!
