Constructors

DVNavLink({Key? key, required DVRouteTarget to, required Widget child, DVLinkPreload preload = DVLinkPreload.visible, DVLinkPreview preview = DVLinkPreview.auto, Future<void> onPreload()?, DVLinkPreviewCallback? onPreview, void openInNewTab(String path)?, EdgeInsets padding = const EdgeInsets.symmetric(horizontal: 4, vertical: 6), bool enabled = true, String? semanticLabel, FocusNode? focusNode, bool autofocus = false})

DVNavLink.external(String url, {Key? key, required Widget child, void openInNewTab(String path)?, EdgeInsets padding = const EdgeInsets.symmetric(horizontal: 4, vertical: 6), bool enabled = true, String? semanticLabel, FocusNode? focusNode, bool autofocus = false})
A link that leaves the site.

Properties

autofocus → bool
Whether this link takes focus when it appears. For the first link on a page a keyboard user has just arrived at.
final
child → Widget
What it looks like.
final
enabled → bool
Whether it navigates. A disabled link still renders.
final
externalUrl → String?
Where this goes when it leaves the site, or null for a route link.
final
focusNode → FocusNode?
The node this link focuses. Supplied where a caller wants to move focus to it, or read it; otherwise the link owns one.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onPreload → Future<void> Function()?
How to fetch the destination. Defaults to the route's own loader.
final
onPreview → DVLinkPreviewCallback?
Where to report the destination, for a status strip or similar.
final
openInNewTab → void Function(String path)?
How to open the destination beside this one, for a middle or modifier click. Defaults to the platform's own way of doing it.
final
padding → EdgeInsets
The hit area around child. Padding here rather than on the child means the space around the label is clickable, so a click that looks on-target does not miss.
final
preload → DVLinkPreload
When to fetch the destination.
final
preview → DVLinkPreview
Whether to show the destination on a rest or a long press.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semanticLabel → String?
What a screen reader reads. Defaults to whatever child announces.
final
to → DVRouteTarget
Where it goes.
