VcDataModelV2 class

Represents a Verifiable Credential (VC) according to the W3C VC Data Model v2.

A Verifiable Credential (VC) is a digitally signed statement, issued by issuer

This class supports JSON serialization and deserialization for interoperability. Example:

VcDataModelV2(
 context: [
   'https://www.w3.org/ns/credentials/v2',
   'https://schema.affinidi.com/UserProfileV1-0.jsonld'
 ],
 id: Uri.parse('uuid:123456abcd'),
 type: {'VerifiableCredential', 'UserProfile'},
 credentialSubject: [
   CredentialSubject({
     'Fname': 'Fname',
     'Lname': 'Lame',
     'Age': '22',
     'Address': 'Eihhornstr'
   })
  ],
 credentialSchema: [
   CredentialSchema(
       id: Uri.parse('https://schema.affinidi.com/UserProfileV1-0.json'),
       type: 'JsonSchemaValidator2018',
   )
 ],
 issuanceDate: DateTime.now(),
 issuer: Issuer.uri(signer.did),
);
