ShadBoxBorder class

A Border that tolerates differently coloured sides inside a radius.

Border.paint throws when given a border radius while the visible sides show more than one colour. Theme animation makes that state routine: lerping a boxed field towards an underlined or borderless style fades three sides out while the bottom crosses to another colour, so mid-flight the sides legitimately disagree. This subclass paints that case as mitred straight sides clipped to the rounded outline — at field hairline widths the corners are indistinguishable from the real thing, and the state only lasts for the frames of the transition.

Properties

bottom → BorderSide
The bottom side of this border.
finalinherited
dimensions → EdgeInsetsGeometry
The widths of the sides of this border represented as an EdgeInsets.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
isUniform → bool
Whether all four sides of the border are identical. Uniform borders are typically more efficient to paint.
no setterinherited
left → BorderSide
The left side of this border.
finalinherited
preferPaintInterior → bool
Reports whether paintInterior is implemented.
no setterinherited
The right side of this border.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
top → BorderSide
The top side of this border.

Methods

add(ShapeBorder other, {bool reversed = false}) → Border?
Attempts to create a new object that represents the amalgamation of this border and the other border.
inherited
getInnerPath(Rect rect, {TextDirection? textDirection}) → Path
Create a Path that describes the inner edge of the border.
inherited
getOuterPath(Rect rect, {TextDirection? textDirection}) → Path
Create a Path that describes the outer edge of the border.
inherited
lerpFrom(ShapeBorder? a, double t) → ShapeBorder?
Linearly interpolates from another ShapeBorder (possibly of another class) to this.
inherited
lerpTo(ShapeBorder? b, double t) → ShapeBorder?
Linearly interpolates from this to another ShapeBorder (possibly of another class).
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Rect rect, {TextDirection? textDirection, BoxShape shape = BoxShape.rectangle, BorderRadius? borderRadius}) → void
Paints the border within the given Rect on the given Canvas.
override
paintInterior(Canvas canvas, Rect rect, Paint paint, {TextDirection? textDirection}) → void
Paint a canvas with the appropriate shape.
inherited
scale(double t) → Border
Creates a copy of this border, scaled by the factor t.
inherited
toString() → String
A string representation of this object.

Operators

operator +(ShapeBorder other) → ShapeBorder
Creates a new border consisting of the two borders on either side of the operator.
inherited
operator ==(Object other) → bool
The equality operator.
