RenderWrap constructor

RenderWrap({List<RenderBox> children, Axis direction: Axis.horizontal, WrapAlignment alignment: WrapAlignment.start, double spacing: 0.0, WrapAlignment runAlignment: WrapAlignment.start, double runSpacing: 0.0, WrapCrossAlignment crossAxisAlignment: WrapCrossAlignment.start, TextDirection textDirection, VerticalDirection verticalDirection: VerticalDirection.down })

Creates a wrap render object.

By default, the wrap layout is horizontal and both the children and the runs are aligned to the start.

Implementation

  List<RenderBox> children,
  Axis direction = Axis.horizontal,
  WrapAlignment alignment = WrapAlignment.start,
  double spacing = 0.0,
  WrapAlignment runAlignment = WrapAlignment.start,
  double runSpacing = 0.0,
  WrapCrossAlignment crossAxisAlignment = WrapCrossAlignment.start,
  TextDirection textDirection,
  VerticalDirection verticalDirection = VerticalDirection.down,
}) : assert(direction != null),
     assert(alignment != null),
     assert(spacing != null),
     assert(runAlignment != null),
     assert(runSpacing != null),
     assert(crossAxisAlignment != null),
     _direction = direction,
     _alignment = alignment,

     _runSpacing = runSpacing,
     _crossAxisAlignment = crossAxisAlignment,
     _textDirection = textDirection,
     _verticalDirection = verticalDirection {
  addAll(children);
