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.

Methods
-
add(
EdgeInsetsGeometry other) → EdgeInsetsGeometry -
Returns the sum of two EdgeInsetsGeometry objects. [...]
override
-
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). [...]override -
subtract(
EdgeInsetsGeometry other) → EdgeInsetsGeometry -
Returns the difference between two EdgeInsetsGeometry objects. [...]
override
-
along(
Axis axis) → double -
The total offset in the given direction.
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
-
toString(
) → String -
Returns a string representation of this object.
