The shape of WaveBottomBar, like a wave
- Inheritance

- Object
- Listenable
- CustomPainter
- WavePainter
Constructors
- WavePainter({required double amplitude, required double waveLength, required Color backgroundColor, required double elevation, required Color shadowColor, required WaveBottomBarDirection direction, required BorderRadius corner, required int barCount, required double percentage})
Properties
- amplitude → double
-
amplitude or height of the wave. If the value is 0, the wave is gone
final
- backgroundColor → Color
-
whole widget background color
final
- barCount → int
-
length of bar item
final
- corner → BorderRadius
-
corner radius of the WaveBottomBar
final
- direction → WaveBottomBarDirection
-
direction of the WaveBottomBar
See WaveBottomBarDirection for more information
final
- elevation → double
-
shadow of the wave
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- percentage → double
-
percentage of active item
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- semanticsBuilder → SemanticsBuilderCallback?
-
Returns a function that builds semantic information for the picture drawn
by this painter.
no setterinherited
- shadowColor → Color
-
shadow color of the wave
final
- waveLength → double
-
length of the wave. If the value is 0, the wave is gone
final
Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be notified when it is time to repaint.
inherited
-
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
sizeargument.override -
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 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).
override
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
