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

```dart title="Dart"
|

|
import 'package:kreuzberg/kreuzberg.dart';
|

|
|
|
||
|
|
Future<void> main() async {
|
||
|
|
// A Dart implementation of the `Validator` trait that asserts a minimum
|
||
|
|
// content length cannot be plugged into the global validator registry.
|
||
|
|
// `Kreuzberg.registerValidator(impl)` exists, but its
|
||
|
|
// `createValidatorDartImpl` factory takes opaque `BoxFn*` closure
|
||
|
|
// arguments whose constructors are not surfaced through
|
||
|
|
// flutter_rust_bridge.
|
||
|
|
//
|
||
|
|
// Implement the validator in Rust and register it via `register_validator`
|
||
|
|
// in a Rust shim crate.
