when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>(TResult $default(String $type, String issuer, @AtUriConverter.new() AtUri uri, String subject, String handle, String displayName, DateTime createdAt, String? revokeReason, DateTime? revokedAt, String? revokedBy, @UVerificationViewSubjectProfileConverter() UVerificationViewSubjectProfile? subjectProfile, @UVerificationViewIssuerProfileConverter() UVerificationViewIssuerProfile? issuerProfile, @UVerificationViewSubjectRepoConverter() UVerificationViewSubjectRepo? subjectRepo, @UVerificationViewIssuerRepoConverter() UVerificationViewIssuerRepo? issuerRepo, Map<String, dynamic>? $unknown,))

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String $type,  String issuer, @AtUriConverter()  AtUri uri,  String subject,  String handle,  String displayName,  DateTime createdAt,  String? revokeReason,  DateTime? revokedAt,  String? revokedBy, @UVerificationViewSubjectProfileConverter()  UVerificationViewSubjectProfile? subjectProfile, @UVerificationViewIssuerProfileConverter()  UVerificationViewIssuerProfile? issuerProfile, @UVerificationViewSubjectRepoConverter()  UVerificationViewSubjectRepo? subjectRepo, @UVerificationViewIssuerRepoConverter()  UVerificationViewIssuerRepo? issuerRepo,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _VerificationView():
return $default(_that.$type,_that.issuer,_that.uri,_that.subject,_that.handle,_that.displayName,_that.createdAt,_that.revokeReason,_that.revokedAt,_that.revokedBy,_that.subjectProfile,_that.issuerProfile,_that.subjectRepo,_that.issuerRepo,_that.$unknown);case _:
  throw StateError('Unexpected subclass');
