EdgeInsetsGeometry class Null safety
Base class for EdgeInsets that allows for text-direction aware resolution.
A property or argument of this type accepts classes created either with EdgeInsets.fromLTRB and its variants, or EdgeInsetsDirectional.fromSTEB and its variants.
To convert an EdgeInsetsGeometry object of indeterminate type into a EdgeInsets object, call the resolve method.

Constructors
- EdgeInsetsGeometry()
-
Abstract const constructor. This constructor enables subclasses to provide
const constructors so that they can be used in const expressions.

Methods
-
add(
EdgeInsetsGeometry other) → EdgeInsetsGeometry - Returns the sum of two EdgeInsetsGeometry objects.
-
along(
Axis axis) → double - The total offset in the given direction.
-
clamp(
EdgeInsetsGeometry min, EdgeInsetsGeometry max) → EdgeInsetsGeometry -
Returns a new EdgeInsetsGeometry object with all values greater than
or equal to
min
, and less than or equal tomax
. -
deflateSize(
Size size) → Size - Returns a new size that is smaller than the given size by the amount of inset in the horizontal and vertical directions.
-
inflateSize(
Size size) → Size - Returns a new size that is bigger than the given size by the amount of inset in the horizontal and vertical directions.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited
-
resolve(
TextDirection? direction) → EdgeInsets -
Convert this instance into an EdgeInsets, which uses literal coordinates
(i.e. the
left
coordinate being explicitly a distance from the left, and theright
coordinate being explicitly a distance from the right). -
subtract(
EdgeInsetsGeometry other) → EdgeInsetsGeometry - Returns the difference between two EdgeInsetsGeometry objects.
-
toString(
) → String -
A string representation of this object.

operator %(
double other) → EdgeInsetsGeometry - Computes the remainder in each dimension by the given factor.
-
operator *(
double other) → EdgeInsetsGeometry - Scales the EdgeInsetsGeometry object in each dimension by the given factor.
-
operator /(
double other) → EdgeInsetsGeometry - Divides the EdgeInsetsGeometry object in each dimension by the given factor.
-
operator ==(
Object other) → bool -
The equality operator.
override
-
operator unary-(
) → EdgeInsetsGeometry - Returns the EdgeInsetsGeometry object with each dimension negated.
-
operator ~/(
double other) → EdgeInsetsGeometry - Integer divides the EdgeInsetsGeometry object in each dimension by the given factor.
Static Methods
-

EdgeInsetsGeometry? a, EdgeInsetsGeometry? b, double t) → EdgeInsetsGeometry? - Linearly interpolate between two EdgeInsetsGeometry objects.
Constants
- infinity → const EdgeInsetsGeometry
-
An EdgeInsetsGeometry with infinite offsets in each direction.
