Properties

advertisedServices → List<String>?

service\[\].type values of the instance's DID document when the control plane last resolved it. Display only: nothing is routed on it. Absent when the document has not been resolved.

final

did → String

The instance's own DID — the identity its signed documents are verified against and the one the control plane addresses.

final

enabledMethods → List<String>?

DID methods the instance can host (e.g. webvh, web, webs), as it declared at registration.

final

ext → Ext?

final

hashCode → int

The hash code for this object.

no setter, inherited

instanceId → String

Stable identifier the control plane uses for this instance. SHOULD be derived from the instance's DID so it survives restarts.

final

label → String?

Operator-chosen display label. Untrusted free text.

final

lastHealthCheck → String?

When the instance last answered a health probe. Absent when it never has.

final

lastInbound → TransportObservation?

The last document the control plane received from this instance. Absent when it has received none.

final

lastOutbound → TransportObservation?

The last document the control plane delivered to this instance. Absent when it has delivered none.

final

publicUrl → String?

The instance's public base URL, where it serves DID resolution. Absent when the instance registered without one.

final

registeredAt → String

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

servedDomains → List<String>

Hosting domains the instance has acknowledged serving. Always present — empty for an instance that serves none, which includes every witness and watcher.

final

servicesCheckedAt → String?

When advertisedServices was last resolved. Absent with it.

final

serviceType → ServiceInstanceServiceType

server — a hosting server (edge) that resolves DIDs the control plane syncs to it. witness — a did:webvh witness. watcher — a did:webvh watcher that mirrors logs.

final

status → ServiceInstanceStatus

The control plane's current verdict, from the instance's last answered health probe. degraded — answered late; unreachable — has not answered within the control plane's configured window.

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

Serialize to a JSON-encodable map, omitting absent members.

toString() → String

A string representation of this object.
