whenOrNull<TResult extends Object?> method

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

A variant of when that fallback to returning null

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return null;
}

Implementation

@optionalTypeArgs TResult? whenOrNull<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() when $default != null:
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 _:
  return null;
