Also worth keeping in mind some of the cross language extension points in Dart.

Compiles to Wasm and can work with other compile to wasm languages.

Has quite good support for C, C++, JS, Swift, Java and Rust interop where they have tools that will write all of the glue code for you.

Also has decent gRPC support meaning you can use any other language that also fits that category.

It’s a small Dart ecosystem but it’s fundamentals are great and it’s extension points are much better than you will likely find elsewhere.
