UDPipeService class

Singleton service that wraps the UDPipe native library via dart:ffi.

Usage:

final svc = UDPipeService();
await svc.init(modelId: 'gsd');
final result = svc.process('Er steigt aus dem Bus aus.');

Constructors

hashCode → int: The hash code for this object.
no setterinherited
isAvailable → bool: Whether a model is loaded and process can be called.
no setter
loadError ↔ String?: Human-readable error message when status is UDPipeStatus.error.
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
status → ValueNotifier<UDPipeStatus>: Current loading state. Listen to this notifier to react to state changes.
final
whenReady → Future<void>: Completes when the current init call finishes (or immediately if idle).
no setter

dispose() → void: Frees the native model handle. Call before loading a different model.
init({String modelId = 'german-gsd'}) → Future<void>: Loads the model identified by modelId (one of kUdpipeModels). Returns immediately if the requested model is already loaded.
initFromAsset(String assetPath) → Future<void>: Loads a model from an arbitrary Flutter asset path.
initFromBytes(Uint8List bytes) → Future<void>: Loads a model directly from bytes (e.g. downloaded at runtime).
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

process(String text) → UDPipeResult: Runs UDPipe on text and returns the parsed result.
processAllBlocksAsync(List<String> blocks) → Future<List<UDPipeResult>>: Processes blocks in a background isolate, yielding one UDPipeResult per block. Keeps the UI thread free for large inputs.
processBatchPerBlock(List<String> blocks) → List<UDPipeResult>: Processes blocks synchronously, returning one UDPipeResult per block.
toString() → String: A string representation of this object.
