LayoutGrid class

Lays out its children using a approximation of the CSS Grid Layout algorithm, as described here:

https://drafts.csswg.org/css-grid/

If a grid item falls outside of the area defined by the template tracks, an FlutterError will be thrown during layout.

Constructors

LayoutGrid({Key? key, AutoPlacement autoPlacement = AutoPlacement.rowSparse, GridFit gridFit = GridFit.expand, String? areas, required List<TrackSize> columnSizes, required List<TrackSize> rowSizes, double? rowGap, double? columnGap, TextDirection? textDirection, List<Widget> children = const []})

Properties

areas → String?
Defines named areas of the grid for placement of grid items by name.
final
autoPlacement → AutoPlacement
Controls how the auto-placement algorithm works, specifying exactly how auto-placed items get flowed into the grid.
final
children → List<Widget>
The widgets below this widget in the tree.
finalinherited
columnGap → double
Space between column tracks
final
columnSizes → List<TrackSize>
Defines the track sizing functions of the grid's columns.
final
gridFit → GridFit
Determines the constraints available to the grid layout algorithm.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
rowGap → double
Space between row tracks
final
rowSizes → List<TrackSize>
Defines the track sizing functions of the grid's rows.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
textDirection → TextDirection?
The text direction used to resolve column ordering.
final

Methods

createElement() → MultiChildRenderObjectElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
createRenderObject(BuildContext context) → RenderLayoutGrid
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.
override
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 RenderLayoutGrid 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.
override

Operators

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