LinkNode<S extends LinkNode<S>> mixin

A URL-addressable grammar node with NO presentation and NO fields — the enum NAME is the whole declaration. The links-only tier of the screens grammar: a server or API surface authors enum _Links with LinkNode<_Links> and builds the same tree (user({product})) with the same link/view-state vocabulary, and nothing to render. A ScreenNodeBase row is conceptually a LinkNode plus a widget; the hierarchy unification (placement-as-link, matcher/generator support) is a coming pass — today this is the authoring surface and the validated tree (LinkGraph).

Properties

fragment → FragmentFace<S>
Like query for the URL #fragment — callable for the PAIRS scheme, .path(...) for the path scheme (#<id>/thumb).
no setter
hashCode → int
The hash code for this object.
no setterinherited
id → Codec<Object?>?
This node's id codec, or null when id-free — an overridable GETTER, so a links-only enum stays completely field-free.
no setter
index → int
A numeric identifier for the enumerated value.
no setterinherited
name → String

Available on Enum, provided by the EnumName extension

The name of the enum value.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

call([Set<TreeNode<S>> children = const {}]) → S
Declares a placement of this node with children as its continuations.
Singular alias of links.
URL ingress branches (slot/nested segs) that resolve to this node.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
query(Set<QueryTerm> terms) → S
This placement's ?query view-state keys — URL-tier, so it lives on the link tier (a server route's query params are the same declaration).
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
