EdgeInsetsDirectional class

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.

const

EdgeInsetsDirectional.symmetric({double horizontal = 0.0, double vertical = 0.0})

Creates insets with symmetric vertical and horizontal offsets.

Methods

add(EdgeInsetsGeometry other) → EdgeInsetsGeometry

Returns the sum of two EdgeInsetsGeometry objects.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent 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

toString() → String

A string representation of this object.

inherited

Operators

operator +(EdgeInsetsDirectional other) → EdgeInsetsDirectional

Returns the sum of two EdgeInsetsDirectional objects.

operator ==(Object other) → bool

The equality operator.

inherited

Constants

zero → const EdgeInsetsDirectional

An EdgeInsetsDirectional with zero offsets in each direction.
