AudioWaveformState()

Properties

absolute bool
Whether to show absolute waveform or not
no setter
activeRatio double
Gets the ratio of elapsedDuration to maxDuration. Used by waveforms that show active track with help of stops in gradient while painting. eg. CurvedPolygonWaveform, SquigglyWaveform
no setter
activeSamples List<double>
Getter for active samples.
no setter
context BuildContext
The location in the tree where this widget builds.
no setterinherited
elapsedDuration Duration?
getter for elapsedDuration
no setter
hashCode int
The hash code for this object.
no setterinherited
invert bool
Whether to invert/flip waveform or not
no setter
maxDuration Duration?
Getter for maxDuration
no setter
mounted bool
Whether this State object is currently in a tree.
no setterinherited
processedSamples List<double>
Getter for processed samples.
no setter
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
sampleWidth double
Getter for sample width.
no setter
showActiveWaveform bool
Whether to show active waveform or not
no setter
waveformAlignment WaveformAlignment
Getter for waveformAlignment.
no setter
widget → T
The current configuration.

Methods

activate() → void
Called when this object is reinserted into the tree after having been removed via deactivate.
inherited
build(BuildContext context) Widget
Describes the part of the user interface represented by this widget.
inherited
deactivate() → void
Called when this object is removed from the tree.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
didChangeDependencies() → void
Called when a dependency of this State object changes.
inherited
didUpdateWidget(covariant T oldWidget) → void
Called whenever the widget configuration changes.
override
dispose() → void
Called when this object is removed from the tree permanently.
inherited
initState() → void
Called when this object is inserted into the tree.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
processSamples() → void
Raw samples are processed before used following some techniques. This is to have consistent samples that can be used to draw the waveform properly.
reassemble() → void
Called whenever the application is reassembled during debugging, for example during hot reload.
inherited
setState(VoidCallback fn) → void
Notify the framework that the internal state of this object has changed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) String
A string representation of this object.
inherited
toStringShort() String
A brief description of this object, usually just the runtimeType and the hashCode.
inherited
updateProcessedSamples(List<double> updatedSamples) → void
Method for subsclass to update the processed samples

Operators
