StaggeredGrid class
A grid which lays out children in a staggered arrangement. Each child can have a different size. Wrap your children with a StaggeredGridTile to specify their size if it's different from a 1x1 tile.

Constructors
-
StaggeredGrid.count({Key? key, required int crossAxisCount, double mainAxisSpacing = 0, double crossAxisSpacing = 0, AxisDirection? axisDirection, List<
Widget> children = const <Widget>[]}) -
Creates a StaggeredGrid using a custom
StaggeredGridDelegateWithFixedCrossAxisCount
as delegate. -
StaggeredGrid.custom({Key? key, required StaggeredGridDelegate delegate, double mainAxisSpacing = 0, double crossAxisSpacing = 0, AxisDirection? axisDirection, List<
Widget> children = const <Widget>[]}) - Creates a StaggeredGrid with a custom delegate.
-
StaggeredGrid.extent({Key? key, required double maxCrossAxisExtent, double mainAxisSpacing = 0, double crossAxisSpacing = 0, AxisDirection? axisDirection, List<
Widget> children = const <Widget>[]}) -
Creates a StaggeredGrid using a custom
StaggeredGridDelegateWithMaxCrossAxisExtent
as delegate.

Methods
-
createElement(
) → MultiChildRenderObjectElement -
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
-
createRenderObject(
BuildContext context) → RenderStaggeredGrid -
Creates an instance of the RenderObject class that this
RenderObjectWidget represents, using the configuration described by this
RenderObjectWidget.
override
-
debugDescribeChildren(
) → List< DiagnosticsNode> -
Returns a list of
DiagnosticsNode
objects describing this node's children.inherited -
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
inherited
-
didUnmountRenderObject(
covariant RenderObject renderObject) → void -
A render object previously associated with this widget has been removed
from the tree. The given RenderObject will be of the same type as
returned by this object's createRenderObject.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString(
{DiagnosticLevel minLevel = DiagnosticLevel.info}) → String -
A string representation of this object.
inherited
-
toStringDeep(
{String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String -
Returns a string representation of this node and its descendants.
inherited
-
toStringShallow(
{String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String -
Returns a one-line detailed description of the object.
inherited
-
toStringShort(
) → String -
A short, textual description of this widget.
inherited
-
updateRenderObject(
BuildContext context, covariant RenderStaggeredGrid renderObject) → void -
Copies the configuration described by this RenderObjectWidget to the
given RenderObject, which will be of the same type as returned by this
object's createRenderObject.

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