LayoutData constructor

const LayoutData({ Object? key, PositionType position = PositionType.relative, LayoutBehavior behavior = LayoutBehavior.none, double flexGrow = 0.0, double flexShrink = 0.0, int? paintOrder, SizeUnit? width = SizeUnit.fitContent, SizeUnit? height = SizeUnit.fitContent, SizeUnit? minWidth, SizeUnit? maxWidth, SizeUnit? minHeight, SizeUnit? maxHeight, PositionUnit? top, PositionUnit? left, PositionUnit? right, PositionUnit? bottom, double? aspectRatio, BoxAlignmentGeometry? alignSelf, })

Creates layout data with the specified properties.

Most parameters are optional and provide fine-grained control over layout behavior. The behavior, flexGrow, and flexShrink parameters are required as they have no sensible defaults.

Example

LayoutData(
  behavior: LayoutBehavior.none,
  flexGrow: 1.0,
  flexShrink: 0.0,
  width: SizeUnit.fixed(100),
  height: SizeUnit.fixed(50),
  alignSelf: BoxAlignmentGeometry.center,
)

Implementation

const LayoutData({
  this.key,
  this.position = PositionType.relative,
  this.behavior = LayoutBehavior.none,
  this.flexGrow = 0.0,
  this.flexShrink = 0.0,
  this.paintOrder,
  this.width = SizeUnit.fitContent,
  this.height = SizeUnit.fitContent,
  this.minWidth,
  this.maxWidth,
  this.minHeight,
  this.maxHeight,
  this.top,
  this.left,
  this.right,
  this.bottom,
  this.aspectRatio,
  this.alignSelf,
});
