RecorderController()

Properties

androidEncoder ↔ AndroidEncoder: getter/setter pair
androidOutputFormat ↔ AndroidOutputFormat: getter/setter pair
currentScrolledDuration → ValueNotifier<int>: Listen to this value notifier when current time position of recorded audio is required.
no setter
hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
hasPermission → bool: If we have microphone permission or not.
no setter
iosEncoder ↔ IosEncoder: getter/setter pair
isRecording → bool: State of recording on/off
no setter
normalizationFactor ↔ double: Db we get from native is too high so in Android it the value is subtracted and in IOS value added
getter/setter pair
recorderState → RecorderState: Current state of the recorder
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sampleRate ↔ int: getter/setter pair
shouldClearLabels ↔ bool: getter/setter pair
shouldRefresh → bool: no setter
updateFrequency ↔ Duration: At which rate waveform needs to be updated
getter/setter pair
waveData → List<double>: Current list of decibels(different values for each platform)

Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
checkPermission() → Future<bool>: This method can be used to check microphone permission. Returns true if we have permission else false.
dispose() → void: This function must be called to free resources, it will also dispose the controller.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
pause() → Future<void>: Use this to pause recording. Can start recording again after pausing.
record([String? path]) → Future<void>: Use this to check permission and starts recording.
refresh() → void: Use this function to get wave to the initial state after scrolling, whether recording is stopped or running.
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
reset() → void: Clears WaveData and labels from the list.
revertClearlabelCall() → void: sets shouldClearLabels flag to false
setRefresh(bool refresh) → void: This function can be used to handle the refresh state. for most cases refresh() should be fine.
setScrolledPostionDuration(int duration) → void: Internally used to set scrolled position to duration.
stop([bool callReset = true]) → Future<String?>: Use this stop recording. Resources are freed after calling this and file is saved. Returns path where file is saved.
toString() → String: A string representation of this object.

Operators

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