whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String $type,
    2. String did,
    3. bool? disabled,
    4. ProfileViewDetailed? profile,
    5. DateTime? createdAt,
    6. DateTime? updatedAt,
    7. String? lastUpdatedBy,
    8. MemberRole role,
    9. 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,  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() when $default != null:
return $default(_that.$type,_that.did,_that.disabled,_that.profile,_that.createdAt,_that.updatedAt,_that.lastUpdatedBy,_that.role,_that.$unknown);case _:
  return null;

}
