InActiveWaveformPainter class abstract
A Painter class that all other InActiveWaveform Painters extend to. This types of waveform painters draws the whole waveform of the audio being played.

Properties
- borderColor → Color

Stroke/Border Width
final
- borderWidth → double
-
Stroke/Border Width
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
- 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
- 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 InActiveWaveformPainter 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 InActiveWaveformPainter oldDelegate) → bool -
Whether the waveform should be rePainted or not.
override
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
