<!-- snippet:skip reason="Dart cannot construct the opaque BoxFn closure types required by createPostProcessorDartImpl — flutter_rust_bridge generates them as RustOpaqueInterface with no Dart-side wrapper. The closure-captured state pattern is therefore unreachable. Custom plugins must be written in Rust." -->

```dart title="Dart"

import 'package:kreuzberg/kreuzberg.dart';

|
|
Future<void> main() async {
|
||
|
|
// A stateful Dart `PostProcessor` that captures mutable counters in its
|
||
|
|
// closure cannot be plugged into the global registry.
|
||
|
|
// `Kreuzberg.registerPostProcessor(impl)` exists, but the
|
||
|
|
// `createPostProcessorDartImpl` factory takes opaque `BoxFn*` closure
|
||
|
|
// values whose constructors are not surfaced through flutter_rust_bridge,
|
||
|
|
// so the closure-capture pattern is unreachable from Dart.
|
||
|
|
//
|
||
|
|
// Implement stateful plugins in Rust using `Mutex`/`AtomicU64` for
|
||
|
|
// interior mutability, then register them in a Rust shim crate.
