ContextPolicy class

Per-context restrictions the VTA enforces. Every member is optional, and absence means unrestricted, not empty — a policy that omits presentableTypes permits every type, while one that sets it to \[\] permits none. The two are opposite instructions and a consumer MUST NOT collapse them.

Constructors

ContextPolicy({List<String>? trustedVerifiers, List<String>? presentableTypes, List<String>? signableKeys, bool? exportAllowed, Map<String, dynamic>? quotas, Ext? ext})

const

ContextPolicy.fromJson(Map<String, dynamic> json)

Read this payload from a decoded JSON object.

Properties

exportAllowed → bool?

Whether material in this context may leave it through an export. Defaults to true; set it to false for a context whose contents must not be extractable.

final

ext → Ext?

final

hashCode → int

The hash code for this object.

no setter, inherited

presentableTypes → List<String>?

Credential types that may be presented from this context. Absent: any type. Present-but-empty: none.

final

quotas → Ext?

Resource limits for the context. Shape is maintainer-defined.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

signableKeys → List<String>?

Key ids the signing oracle may be invoked on within this context. Absent: every key the context holds. Present-but-empty: no keys.

final

trustedVerifiers → List<String>?

VIDs permitted to receive presentations from this context. Absent: any verifier. Present-but-empty: none.

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.
