when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>(TResult $default(String id, String token, DateTime expiresAt, DateTime? createdAt, DateTime? updatedAt, String? ipAddress, String? userAgent, String userId, String? impersonatedBy, String? activeOrganizationId, String? activeTeamId, @JsonKey.new(readValue: _readSessionAdditionalFields, includeToJson: false) Map<String, dynamic> additionalFields,))

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 id,  String token,  DateTime expiresAt,  DateTime? createdAt,  DateTime? updatedAt,  String? ipAddress,  String? userAgent,  String userId,  String? impersonatedBy,  String? activeOrganizationId,  String? activeTeamId, @JsonKey(readValue: _readSessionAdditionalFields, includeToJson: false)  Map<String, dynamic> additionalFields)  $default,) {final _that = this;
switch (_that) {
case _Session():
return $default(_that.id,_that.token,_that.expiresAt,_that.createdAt,_that.updatedAt,_that.ipAddress,_that.userAgent,_that.userId,_that.impersonatedBy,_that.activeOrganizationId,_that.activeTeamId,_that.additionalFields);case _:
  throw StateError('Unexpected subclass');
