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.

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