BubbleTabIndicator class

Used with TabBar.indicator to draw a bubble on the selected tab.

The indicatorHeight defines the bubble height. The indicatorColor defines the bubble color. The indicatorRadius defines the bubble corner radius. The tabBarIndicatorSize specifies the type of TabBarIndicatorSize i.e label or tab. /// The selected tab bubble is inset from the tab's boundary by insets when tabBarIndicatorSize is tab. The selected tab bubble is applied padding by padding when tabBarIndicatorSize is label.

Properties

hashCode → int
The hash code for this object.
no setterinherited
indicatorColor → Color
final
indicatorHeight → double
final
indicatorRadius → double
final
insets → EdgeInsetsGeometry
final
isComplex → bool
Whether this decoration is complex enough to benefit from caching its painting.
no setterinherited
padding → EdgeInsetsGeometry
Returns the insets to apply when using this decoration on a box that has contents, so that the contents do not overlap the edges of the decoration. For example, if the decoration draws a frame around its edge, the padding would return the distance by which to inset the children so as to not overlap the frame.

runtimeType → Type
A representation of the runtime type of the object.

tabBarIndicatorSize → TabBarIndicatorSize

Methods

createBoxPainter([VoidCallback? onChanged]) → _BubblePainter
Returns a BoxPainter that will paint this decoration.
override
debugAssertIsValid() → bool
In debug mode, throws an exception if the object is not in a valid configuration. Otherwise, returns true.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
getClipPath(Rect rect, TextDirection textDirection) → Path
Returns a closed Path that describes the outer edge of this decoration.
inherited
hitTest(Size size, Offset position, {TextDirection? textDirection}) → bool
Tests whether the given point, on a rectangle of a given size, would be considered to hit the decoration or not. For example, if the decoration only draws a circle, this function might return true if the point was inside the circle and false otherwise.
inherited
lerpFrom(Decoration? a, double t) → Decoration?
Linearly interpolates from another Decoration (which may be of a different class) to this.
override
lerpTo(Decoration? b, double t) → Decoration?
Linearly interpolates from this to another Decoration (which may be of a different class).
override
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
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.

Operators

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