MaterialStateOutlinedBorder class Null safety

Defines an OutlinedBorder whose value depends on a set of MaterialStates which represent the interactive state of a component.

To use a MaterialStateOutlinedBorder, you should create a subclass of an OutlinedBorder and implement MaterialStateOutlinedBorder's abstract resolve method.

This example defines a subclass of RoundedRectangleBorder and an implementation of MaterialStateOutlinedBorder, that resolves to RoundedRectangleBorder when its widget is selected.
To create a local project with this code sample, run:
flutter create --sample=material.MaterialStateOutlinedBorder.1 mysample

This class should only be used for parameters which are documented to take MaterialStateOutlinedBorder, otherwise only the default state will be used.

Methods

add(ShapeBorder other, {bool reversed = false}) → ShapeBorder?
Attempts to create a new object that represents the amalgamation of this border and the other border.
protected">@protectedinherited
copyWith({BorderSide? side}) → OutlinedBorder
Returns a copy of this OutlinedBorder that draws its outline with the specified side, if side is non-null.
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 non-existent method or property is accessed.
inherited
paint(Canvas canvas, Rect rect, {TextDirection? textDirection}) → void
Paints the border within the given Rect on the given Canvas.
inherited
resolve(Set<MaterialState> states) → OutlinedBorder?
Returns an OutlinedBorder that's to be used when a Material component is in the specified state. Return null to defer to the default value of the widget or theme.
override
scale(double t) → ShapeBorder
Creates a copy of this border, scaled by the factor t.
inherited
toString() → String
A string representation of this object.
