AudioWaveform({Key? key, required List<double> samples, required double height, required double width, Duration? maxDuration, Duration? elapsedDuration, required bool showActiveWaveform, bool absolute = false, bool invert = false})
Constructor for AudioWaveform

Properties

absolute → bool
Makes the waveform absolute. Draws the waveform along the positive y-axis. Samples are processed such that we end up with positive sample values.
final
elapsedDuration → Duration?
Elapsed duration of the audio.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double
Height of the canvas on which the waveform will be drawn.
final
invert → bool
Inverts/Flips the waveform along x-axis. Samples are processed such that we end up with samples having opposite sign.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
maxDuration → Duration?
Maximum duration of the audio.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
samples → List<double>
Audio samples raw input. This raw samples are processed before being used to paint the waveform.
final
showActiveWaveform → bool
Whether to show the active waveform or not.
final
waveformAlignment → WaveformAlignment
Alignment of the waveform in the canvas.
final
width → double
Width of the canvas on which the waveform will be drawn.
final

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → AudioWaveformState<AudioWaveform>
Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
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
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A short, textual description of this widget.
