-
-/// A delegate that controls the layout of multiple children.
-///
-/// Used with [CustomMultiChildLayout] (in the widgets library) and
-/// [RenderCustomMultiChildLayoutBox] (in the rendering library).
-///
-/// Delegates must be idempotent. Specifically, if two delegates are equal, then
-/// they must produce the same layout. To change the layout, replace the
-/// delegate with a different instance whose [shouldRelayout] returns true when
-/// given the previous instance.
-///
-/// Override [getSize] to control the overall size of the layout. The size of
-/// the layout cannot depend on layout properties of the children. This was
-/// a design decision to simplify the delegate implementations: This way,
-/// the delegate implementations do not have to also handle various intrinsic
-/// sizing functions if the parent's size depended on the children.
-/// If you want to build a custom layout where you define the size of that widget
-/// based on its children, then you will have to create a custom render object.
-/// See [MultiChildRenderObjectWidget] with [ContainerRenderObjectMixin] and
-/// [RenderBoxContainerDefaultsMixin] to get started or [RenderStack] for an
-/// example implementation.
-///
-/// Override [performLayout] to size and position the children. An
-/// implementation of [performLayout] must call [layoutChild] exactly once for
-/// each child, but it may call [layoutChild] on children in an arbitrary order.
-/// Typically a delegate will use the size returned from [layoutChild] on one
-/// child to determine the constraints for [performLayout] on another child or
-/// to determine the offset for [positionChild] for that child or another child.
-///
-/// Override [shouldRelayout] to determine when the layout of the children needs
-/// to be recomputed when the delegate changes.
-///
-/// The most efficient way to trigger a relayout is to supply a `relayout`
-/// argument to the constructor of the [MultiChildLayoutDelegate]. The custom
-/// layout will listen to this value and relayout whenever the Listenable
-/// notifies its listeners, such as when an [Animation] ticks. This allows
-/// the custom layout to avoid the build phase of the pipeline.
-///
-/// Each child must be wrapped in a [LayoutId] widget to assign the id that
-/// identifies it to the delegate. The [LayoutId.id] needs to be unique among
-/// the children that the [CustomMultiChildLayout] manages.
-///
-/// {@tool snippet}
-///
-/// Below is an example implementation of [performLayout] that causes one widget
-/// (the follower) to be the same size as another (the leader):
-///
-/// ```dart
-/// // Define your own slot numbers, depending upon the id assigned by LayoutId.
-/// // Typical usage is to define an enum like the one below, and use those
-/// // values as the ids.
-/// enum _Slot {
-///   leader,
-///   follower,
-/// }
-///
-/// class FollowTheLeader extends MultiChildLayoutDelegate {
-///   @override
-///   void performLayout(Size size) {
-///     Size leaderSize = Size.zero;
-///
-///     if (hasChild(_Slot.leader)) {
-///       leaderSize = layoutChild(_Slot.leader, BoxConstraints.loose(size));

-/// A Material Design "Text Button".
-///
-/// Use text buttons on toolbars, in dialogs, or inline with other
-/// content but offset from that content with padding so that the
-/// button's presence is obvious. Text buttons do not have visible
-/// borders and must therefore rely on their position relative to
-/// other content for context. In dialogs and cards, they should be
-/// grouped together in one of the bottom corners. Avoid using text
-/// buttons where they would blend in with other content, for example
-/// in the middle of lists.
-///
-/// A text button is a label [child] displayed on a (zero elevation)
-/// [Material] widget. The label's [Text] and [Icon] widgets are
-/// displayed in the [style]'s [ButtonStyle.foregroundColor]. The
-/// button reacts to touches by filling with the [style]'s
-/// [ButtonStyle.backgroundColor].
-///
-/// The text button's default style is defined by [defaultStyleOf].
-/// The style of this text button can be overridden with its [style]
-/// parameter. The style of all text buttons in a subtree can be
-/// overridden with the [TextButtonTheme] and the style of all of the
-/// text buttons in an app can be overridden with the [Theme]'s
-/// [ThemeData.textButtonTheme] property.
-///
-/// The static [styleFrom] method is a convenient way to create a
-/// text button [ButtonStyle] from simple values.
-///
-/// If the [onPressed] and [onLongPress] callbacks are null, then this
-/// button will be disabled, it will not react to touch.
-///
-/// {@tool dartpad}
-/// This sample shows various ways to configure TextButtons, from the
-/// simplest default appearance to versions that don't resemble
-/// Material Design at all.
-///
-/// ** See code in examples/api/lib/material/text_button/text_button.0.dart **
-/// {@end-tool}
-///
-/// {@tool dartpad}
