EdgeInsetsDirectional class Null safety

An immutable set of offsets in each of the four cardinal directions, but whose horizontal components are dependent on the writing direction.

This can be used to indicate padding from the left in TextDirection.ltr text and padding from the right in TextDirection.rtl text without having to be aware of the current text direction.

  • EdgeInsets, a variant that uses physical labels (left and right instead of start and end).

Constructors

EdgeInsetsDirectional.all(double value)
Creates insets where all the offsets are value.
const
EdgeInsetsDirectional.fromSTEB(double start, double top, double end, double bottom)
Creates insets from offsets from the start, top, end, and bottom.
const
EdgeInsetsDirectional.only({double start = 0.0, double top = 0.0, double end = 0.0, double bottom = 0.0})
Creates insets with only the given values non-zero.

end → double
The offset from the end side, the side on which the user ends reading text.
final
flipped → EdgeInsetsDirectional
An EdgeInsetsDirectional with top and bottom as well as start and end flipped.

Methods

add(EdgeInsetsGeometry other) → EdgeInsetsGeometry
Returns the sum of two EdgeInsetsGeometry objects.
override
along(Axis axis) → double
The total offset in the given direction.
inherited
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 to max.
inherited
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.
inherited
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.
inherited
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 the right coordinate being explicitly a distance from the right).
override
subtract(EdgeInsetsGeometry other) → EdgeInsetsGeometry
Returns the difference between two EdgeInsetsGeometry objects.
override
toString() → String
A string representation of this object.

Operators

operator %(double other) → EdgeInsetsDirectional

override
operator *(double other) → EdgeInsetsDirectional
Scales the EdgeInsetsDirectional object in each dimension by the given factor.
override
operator +(EdgeInsetsDirectional other) → EdgeInsetsDirectional
Returns the sum of two EdgeInsetsDirectional objects.
operator -(EdgeInsetsDirectional other) → EdgeInsetsDirectional
Returns the difference between two EdgeInsetsDirectional objects.
operator /(double other) → EdgeInsetsDirectional
Divides the EdgeInsetsDirectional object in each dimension by the given factor.
override
operator ==(Object other) → bool
The equality operator.
inherited
operator unary-() → EdgeInsetsDirectional
Returns the EdgeInsetsDirectional object with each dimension negated.
override
operator ~/(double other) → EdgeInsetsDirectional
Integer divides the EdgeInsetsDirectional object in each dimension by the given factor.

Static Methods

lerp(EdgeInsetsDirectional? a, EdgeInsetsDirectional? b, double t) → EdgeInsetsDirectional?
Linearly interpolate between two EdgeInsetsDirectional.
