ListBody class
A widget that arranges its children sequentially along a given axis, forcing them to the dimension of the parent in the other axis.
This widget is rarely used directly. Instead, consider using ListView, which combines a similar layout algorithm with scrolling behavior, or Column, which gives you more flexible control over the layout of a vertical set of boxes.
See also:
- RenderListBody, which implements this layout algorithm and the documentation for which describes some of its subtleties.
- SingleChildScrollView, which is sometimes used with ListBody to make the contents scrollable.
- Column and Row, which implement a more elaborate version of this layout algorithm (at the cost of being slightly less efficient).
- ListView, which implements an efficient scrolling version of this layout algorithm.

Methods
- createElement(
) → MultiChildRenderObjectElement - RenderObjectWidgets always inflate to a RenderObjectElement subclass. inherited
- createRenderObject(
BuildContext context) → RenderListBody - 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 - This method is called when a RenderObject that was previously associated with this widget is removed from the render tree. The provided RenderObject will be of the same type as the one created by this widget's createRenderObject method. 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, int wrapWidth = 65}) → 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 RenderListBody 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. inherited
