when<TResult extends Object?> method
- @optionalTypeArgs
- TResult $default(
- String $type,
- String did,
- bool? disabled,
- ProfileViewDetailed? profile,
- DateTime? createdAt,
- DateTime? updatedAt,
- String? lastUpdatedBy,
- MemberRole role,
- 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 did, bool? disabled, @ProfileViewDetailedConverter() ProfileViewDetailed? profile, DateTime? createdAt, DateTime? updatedAt, String? lastUpdatedBy, @MemberRoleConverter() MemberRole role, Map<String, dynamic>? $unknown) $default,) {final _that = this;
switch (_that) {
case _Member():
return $default(_that.$type,_that.did,_that.disabled,_that.profile,_that.createdAt,_that.updatedAt,_that.lastUpdatedBy,_that.role,_that.$unknown);case _:
throw StateError('Unexpected subclass');
}
