Methods

analyzeSamples(int requestId, Uint8List float32Samples) → Future<void>
Feeds interleaved samples to a stream analysis, as the bytes of a little-endian Float32List (Pigeon has no float32 list type).
cancel(int requestId) → Future<void>
Stops an analysis. No further callbacks arrive for requestId.
cancelAll() → Future<int>
Stops every analysis. Returns how many were running.
classifierInfo(ClassifierConfigMessage config) → Future<ClassifierInfoMessage>
Labels, window defaults and window constraints of a classifier.
completeStreamAnalysis(int requestId) → Future<void>
Flushes a stream analysis; its last results and completion follow.
microphonePermission() → Future<MicrophonePermissionMessage>
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
requestMicrophonePermission() → Future<bool>
startFileAnalysis(int requestId, String path, ClassifierConfigMessage config, int? maximumClassifications) → Future<void>
Starts classifying an audio file. Returns once the analysis has started; results follow through the callback API.
startMicrophoneAnalysis(int requestId, ClassifierConfigMessage config, int? maximumClassifications) → Future<void>
Starts classifying the microphone until cancel is called.
startStreamAnalysis(int requestId, AudioFormatMessage format, ClassifierConfigMessage config, int? maximumClassifications) → Future<void>
Starts an analysis of PCM audio that Dart pushes with analyzeSamples.
toString() → String
A string representation of this object.
