AudioRecorderController()

Properties

audioLevelObs → RxDouble: Observable audio level (decibels normalized to 0.0-1.0)
final

no setterinherited
hasRecordedFile → bool: Whether a recorded file exists and is ready for use
no setteroverride
initialized → bool: Checks whether the controller has already been initialized.
no setterinherited
isClosed → bool: Checks whether the controller has already been closed.
no setterinherited
isDisposed → bool: no setterinherited
isPaused → bool: no setter
isPausedObs → RxBool: final
isRecording → bool: Whether the recorder is currently recording
no setteroverride
isRecordingObs → RxBool: Observable state for UI binding
final
listenersLength → int: no setterinherited
recordedBytes → Future<Uint8List?>: Raw bytes of the recorded audio — convenience for voice cloning and TTS reference audio without manual file I/O.
no setteroverride
recordedFile → File?: File object of the recorded audio (if exists)
no setteroverride
recordedFilePath → String?: Path to the recorded audio file (if exists)
no setteroverride
recordingDurationSeconds → int: Duration of the current/last recording in seconds
no setteroverride
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

Methods

addListener(SintStateUpdate listener) → Disposer: Register a closure to be called when the object notifies its listeners.
inherited
addListenerId(Object? key, SintStateUpdate listener) → Disposer: inherited
cancelRecording() → Future<void>: Cancel recording and delete any partial file
override
clearRecording() → void: Clear the recorded file after upload/use
override
containsListener(SintStateUpdate listener) → bool: inherited
debounce<T>(RxInterface<T> rx, void callback(T), {Duration duration = const Duration(milliseconds: 400)}) → void: Calls callback after rx stops changing for duration. Useful for search-as-you-type, form validation, etc.
inherited
dispose() → void: inherited
disposeRecorder() → Future<void>: Dispose resources
override
ever<T>(RxInterface<T> rx, void callback(T)) → void: Calls callback every time rx changes. Auto-cancels on controller disposal.
inherited
formatDuration(int seconds) → String: Format duration as MM:SS
initialize() → Future<bool>: Initialize the recorder (request permissions, open recorder)
override
interval<T>(RxInterface<T> rx, void callback(T), {Duration duration = const Duration(seconds: 1)}) → void: Calls callback at most once per duration, ignoring intermediate changes. Useful for rate-limiting UI updates.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
once<T>(RxInterface<T> rx, void callback(T)) → void: Calls callback only the first time rx changes, then cancels.
inherited
onClose() → void: Called before onDelete method. onClose might be used to dispose resources used by the controller. Like closing events, or streams before the controller is destroyed. Or dispose objects that can potentially create some memory leaks, like TextEditingControllers, AnimationControllers. Might be useful as well to persist some data on disk.
override
onDelete() → void: inherited
onInit() → void: Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.
override
onReady() → void: Called 1 frame after onInit(). It is the perfect place to enter navigation events, like snackbar, dialogs, or a new route, or async request.
inherited
onStart() → void: Called at the exact moment the widget is allocated in memory. It uses an internal "callable" type, to avoid any @overrides in subclasses. This method should be internal and is required to define the lifetime cycle of the subclass.
inherited
pauseRecording() → Future<bool>: Pause recording
refresh() → void: inherited
refreshGroup(Object id) → void: inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that the object notifies.
inherited
removeListenerId(Object id, VoidCallback listener) → void: inherited
reportAdd(VoidCallback disposer) → void: inherited
reportRead() → void: inherited
resumeRecording() → Future<bool>: Resume recording
startRecording() → Future<bool>: Start recording audio to a temporary file
override
stopRecording() → Future<bool>: Stop recording and finalize the file
override
toString() → String: A string representation of this object.
inherited
update([List<Object>? ids, bool condition = true]) → void: Notifies listeners to update the UI.

Operators

operator ==(Object other) → bool: The equality operator.
