whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(String $type, String did, String handle, String? email, List<Map<String, dynamic>> relatedRecords, DateTime indexedAt, ModerationDetail moderation, List<Label>? labels, InviteCode? invitedBy, List<InviteCode>? invites, bool? invitesDisabled, String? inviteNote, DateTime? emailConfirmedAt, DateTime? deactivatedAt, List<ThreatSignature>? threatSignatures, 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 did,  String handle,  String? email,  List<Map<String, dynamic>> relatedRecords,  DateTime indexedAt, @ModerationDetailConverter()  ModerationDetail moderation, @LabelConverter()  List<Label>? labels, @InviteCodeConverter()  InviteCode? invitedBy, @InviteCodeConverter()  List<InviteCode>? invites,  bool? invitesDisabled,  String? inviteNote,  DateTime? emailConfirmedAt,  DateTime? deactivatedAt, @ThreatSignatureConverter()  List<ThreatSignature>? threatSignatures,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _RepoViewDetail() when $default != null:
return $default(_that.$type,_that.did,_that.handle,_that.email,_that.relatedRecords,_that.indexedAt,_that.moderation,_that.labels,_that.invitedBy,_that.invites,_that.invitesDisabled,_that.inviteNote,_that.emailConfirmedAt,_that.deactivatedAt,_that.threatSignatures,_that.$unknown);case _:
  return null;
