<itemvalue="Lists the sub-directories and files of this [Directory]. Optionally recurses into sub-directories. If [followLinks] is `false`, then any symbolic links found are reported as [Link] objects, rather than as directories or files, and are not recursed into. If [followLinks] is `true`, then working links are reported as directories or files, depending on what they point to, and links to directories are recursed into if [recursive] is `true`. Broken links are reported as [Link] objects. If a symbolic link makes a loop in the file system, then a recursive listing will not follow a link twice in the same recursive descent, but will report it as a [Link] the second time it is seen. The result is a [Stream] of [FileSystemEntity] objects for the directories, files, and links. The [Stream] will be in an arbitrary order and does not include the special entries `'.'` and `'..'`."/>

<itemvalue="Called when a [ScrollPosition] is attached to the scroll controller. Since a scroll position is not attached until a [Scrollable] is actually built, this can be used to respond to a new position being attached. At the time that a scroll position is attached, the [ScrollMetrics], such as the [ScrollMetrics.maxScrollExtent], are not yet available. These are not determined until the [Scrollable] has finished laying out its contents and computing things like the full extent of that content. [ScrollPosition.hasContentDimensions] can be used to know when the metrics are available, or a [ScrollMetricsNotification] can be used, discussed further below. {@tool dartpad} This sample shows how to apply a listener to the [ScrollPosition.isScrollingNotifier] using [ScrollController.onAttach]. This is used to change the [AppBar]'s color when scrolling is occurring. See code in examplesapilibwidgetsscroll_positionscroll_controller_on_attach.0.dart {@end-tool}"/>
