DirectionalEdgeInsetsDensity class

Direction-aware density edge insets using start/end instead of left/right.

Use this for RTL-aware layouts. The start and end values are multipliers that will be multiplied by the base padding from Density.

Example:

// Creates padding that adapts to density and text direction
const DirectionalEdgeInsetsDensity.symmetric(
  horizontal: padLg,  // 1.0 * basePadding on start and end
  vertical: padSm,    // 0.5 * basePadding on top and bottom
)

Constructors

DirectionalEdgeInsetsDensity.all(double value)
Creates directional density insets with the same value on all sides.
const
DirectionalEdgeInsetsDensity.only({double start = 0.0, double top = 0.0, double end = 0.0, double bottom = 0.0})
Creates directional density insets with individual values.
const
DirectionalEdgeInsetsDensity.symmetric({double vertical = 0.0, double horizontal = 0.0})
Creates directional density insets with symmetric values.

finalinherited
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.
inherited
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
copyWith({double? start, double? top, double? end, double? bottom}) → DirectionalEdgeInsetsDensity
Creates a copy of this EdgeInsetsDirectional but with the given fields replaced with the new values.
override
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 nonexistent method or property is accessed.
inherited
optionallyResolve(BuildContext context) → EdgeInsets

Available on EdgeInsetsGeometry, provided by the EdgeInsetsExtension extension

Resolves to EdgeInsets, skipping resolution if already resolved.
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).
inherited
resolveDensity(double basePadding) → EdgeInsetsDirectional
Resolves the density multipliers to actual pixel values.
override
subtract(EdgeInsetsGeometry other) → EdgeInsetsGeometry
Returns the difference between two EdgeInsetsGeometry objects.
inherited
toString() → String
A string representation of this object.

inherited
operator *(double other) → EdgeInsetsDirectional
Scales the EdgeInsetsDirectional object in each dimension by the given factor.
inherited
operator +(EdgeInsetsDirectional other) → EdgeInsetsDirectional
Returns the sum of two EdgeInsetsDirectional objects.
inherited
operator -(EdgeInsetsDirectional other) → EdgeInsetsDirectional

inherited
operator ==(Object other) → bool
The equality operator.
inherited
operator unary-() → EdgeInsetsDirectional

inherited
operator ~/(double other) → EdgeInsetsDirectional
Integer divides the EdgeInsetsDirectional object in each dimension by the given factor.
