Dart Isolates

tip

There is no need to read this page, unless you need to use it in multiple Dart Isolates.

To use Dart Isolates, just call RustLib.init() and RustLib.dispose() when your isolate starts and stops, just like how you deal with many standard Flutter objects.

Working examples (tests that are executed in CI) can be seen here.

As a remark, often there is no need to use Dart Isolates when interacting with flutter_rust_bridge. Since flutter_rust_bridge supports async, even if your Rust function is super slow, it will never block the Dart code.
