SliverMasonryGrid class

A sliver that places multiple box children in a two dimensional arrangement.

SliverMasonryGrid places each child the nearest as possible at the start of the main axis and then at the start of the cross axis. For example, in a vertical list, with left-to-right text direction, a child will be placed as close as possible at the top of the grid, and then as close as possible to the left side of the grid.

The gridDelegate determines how many children can be placed in the cross axis.

Constructors

SliverMasonryGrid({Key? key, required SliverChildDelegate delegate, required SliverSimpleGridDelegate gridDelegate, double mainAxisSpacing = 0, double crossAxisSpacing = 0})
Creates a sliver that places its children in a Masonry arrangement.
const
SliverMasonryGrid.count({Key? key, required int crossAxisCount, required IndexedWidgetBuilder itemBuilder, int? childCount, double mainAxisSpacing = 0, double crossAxisSpacing = 0})
Creates a sliver that places multiple box children in a Masonry arrangement with a fixed number of tiles in the cross axis.
SliverMasonryGrid.extent({Key? key, required double maxCrossAxisExtent, required IndexedWidgetBuilder itemBuilder, int? childCount, double mainAxisSpacing = 0, double crossAxisSpacing = 0})
Creates a sliver that places multiple box children in a Masonry arrangement with tiles that each have a maximum cross-axis extent.

Methods

createElement() SliverMultiBoxAdaptorElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
createRenderObject(BuildContext context) RenderSliverMasonryGrid
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
estimateMaxScrollOffset(SliverConstraints? constraints, int firstIndex, int lastIndex, double leadingScrollOffset, double trailingScrollOffset) double?
Returns an estimate of the max scroll extent for all the children.
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 RenderSliverMasonryGrid 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.
