ActiveInActiveWaveformPainter class abstract

A Painter class that all other ActiveInActiveWaveform Painters extend to. The members of this class are essential to draw any waveform that manages the painting of both active and inActive waveform within itself.

Constructors

ActiveInActiveWaveformPainter({required Color activeColor, required List<double> samples, required double sampleWidth, required Color inactiveColor, required double activeRatio, required WaveformAlignment waveformAlignment, PaintingStyle style = PaintingStyle.stroke, required double strokeWidth})

Properties

activeColor → Color
The color of the inactive waveform.
final
activeRatio → double
The ratio of the elapsedDuration to the maxDuration.
final
color → Color
Color of the waveform.
finalinherited
gradient → Gradient?
Gradient of the waveform.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
inactiveColor → Color
The color of the active waveform.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
samples → List<double>
Samples that are used to paint the waveform.
finalinherited
sampleWidth → double
Width of each sample.
finalinherited
semanticsBuilder → SemanticsBuilderCallback?
Returns a function that builds semantic information for the picture drawn by this painter.
no setterinherited
strokeWidth → double
Stroke Width
final
style → PaintingStyle
The style of the waveform.
finalinherited
waveformAlignment → WaveformAlignment
Alignment of the waveform.

Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
getShouldRepaintValue(covariant ActiveInActiveWaveformPainter oldDelegate) → bool
Get shoudlRepaintValue
hitTest(Offset position) → bool?
Called whenever a hit test is being performed on an object that is using this custom paint delegate.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Size size) → void
Called whenever the object needs to paint. The given Canvas has its coordinate space configured such that the origin is at the top left of the box. The area of the box is the size of the size argument.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies when it is time to repaint.
inherited
shouldRebuildSemantics(covariant CustomPainter oldDelegate) → bool
Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
inherited
shouldRepaint(covariant ActiveInActiveWaveformPainter oldDelegate) → bool
Whether the waveform should be rePainted or not.
override
toString() → String
A string representation of this object.

Operators

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