<!-- 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 ProcessingStage enum is also not surfaced. Custom post-processors must be written in Rust." -->

import 'package:kreuzberg/kreuzberg.dart';

Future<void> main() async {

// A Dart implementation of the `PostProcessor` trait that gates on PDF

|
|
// MIME type cannot be plugged into the global registry.
|
||
|
|
// `Kreuzberg.registerPostProcessor(impl)` exists, but its
|
||
|
|
// `createPostProcessorDartImpl` factory takes opaque `BoxFn*` closure
|
||
|
|
// values plus a `BoxFnDartFnFutureProcessingStage` whose constructors are
|
||
|
|
// not surfaced through flutter_rust_bridge. The `ProcessingStage` enum is
|
||
|
|
// not exported to Dart either.
|
||
|
|
//
|
||
|
|
// Implement the post-processor in Rust as `Plugin + PostProcessor` and
|
||
|
|
// register it via `register_post_processor` in a Rust shim crate.
