<!-- snippet:skip reason="Dart cannot construct the opaque BoxFn closure types required by createEmbeddingBackendDartImpl — flutter_rust_bridge generates them as RustOpaqueInterface with no Dart-side wrapper. Custom embedding backends must be written in Rust." -->

```dart title="Dart"

import 'package:kreuzberg/kreuzberg.dart';

Future<void> main() async {
|

|
|
// A Dart implementation of the `EmbeddingBackend` trait cannot be plugged
|
||
|
|
// into the global registry. `Kreuzberg.registerEmbeddingBackend(impl)`
|
||
|
|
// exists, but its `createEmbeddingBackendDartImpl` factory takes opaque
|
||
|
|
// `BoxFn*` closure values whose constructors are not surfaced through
|
||
|
|
// flutter_rust_bridge.
|
||
|
|
//
|
||
|
|
// Implement the backend in Rust as `Plugin + EmbeddingBackend` and register
|
||
|
|
// it via `register_embedding_backend` in a Rust shim crate.
