TableViewCell class

Creates a cell of the TableView, along with information regarding merged cells and RepaintBoundarys.

When merging cells in a TableView, the same child with the same merge information must be returned from every vicinity the merged cell contains. The build method will only be called once for a merged cell, but since the table's children are lazily laid out, returning the same child and merge information ensures the merged cell can be built no matter which part of it is visible.

For example, if a cell is configured to span 3 columns, starting at column 1, the cellBuilder of the TableView must return a TableViewCell with the same child, columnMergeStart as 1, and columnMergeSpan as 3 for all three TableVicinitys (column 1, 2, and 3). If the merge information is only provided for the first vicinity (column 1), and that vicinity is scrolled out of the viewport and cacheExtent, the table will not know the following vicinities (column 2 and 3) are part of a merge and will "unmerge" them.

Methods

animate({Key? key, List<Effect>? effects, AnimateCallback? onInit, AnimateCallback? onPlay, AnimateCallback? onComplete, bool? autoPlay, Duration? delay, AnimationController? controller, Adapter? adapter, double? target, double? value}) → Animate

Available on Widget, provided by the AnimateWidgetExtensions extension

Wraps the target Widget in an Animate instance, and returns the instance for chaining calls. Ex. myWidget.animate() is equivalent to Animate(child: myWidget).
build(BuildContext context) → Widget
Describes the part of the user interface represented by this widget.
override
createElement() → StatelessElement
Creates a StatelessElement to manage this widget's location in the tree.
inherited
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
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
positionedWith(ShadPosition position) → Widget

Available on Widget, provided by the PositionedExt extension

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.
