Table class Null safety

A widget that uses the table layout algorithm for its children.

link
This sample shows a Table with borders, multiple types of column widths and different vertical cell alignments.
To create a local project with this code sample, run:
flutter create --sample=widgets.Table.1 mysample

If you only have one row, the Row widget is more appropriate. If you only have one column, the SliverList or Column widgets will be more appropriate.

Rows size vertically based on their contents. To control the individual column widths, use the columnWidths property to specify a TableColumnWidth for each column. If columnWidths is null, or there is a null entry for a given column in columnWidths, the table uses the defaultColumnWidth instead.

By default, defaultColumnWidth is a FlexColumnWidth. This TableColumnWidth divides up the remaining space in the horizontal axis to determine the column width. If wrapping a Table in a horizontal ScrollView, choose a different TableColumnWidth, such as FixedColumnWidth.

For more details about the table layout algorithm, see RenderTable. To control the alignment of children, see TableCell.

Methods

createElement() → RenderObjectElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
override
createRenderObject(BuildContext context) → RenderTable
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.
protected">@protectedinherited
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.
protected">@protectedinherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent 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 RenderTable 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.
