when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String id,
    2. int onboardingStep,
    3. bool isEmailVerified,
    4. bool isPhoneVerified,
    5. bool isProfileCompleted,
    6. String status,
    7. String displayName,
    8. String? username,
    9. String? email,
    10. String? phoneNumber,
    11. String? countryCode,
    12. List<String> roles,
    )
)

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,  int onboardingStep,  bool isEmailVerified,  bool isPhoneVerified,  bool isProfileCompleted,  String status,  String displayName,  String? username,  String? email,  String? phoneNumber,  String? countryCode,  List<String> roles)  $default,) {final _that = this;
switch (_that) {
case _User():
return $default(_that.id,_that.onboardingStep,_that.isEmailVerified,_that.isPhoneVerified,_that.isProfileCompleted,_that.status,_that.displayName,_that.username,_that.email,_that.phoneNumber,_that.countryCode,_that.roles);case _:
  throw StateError('Unexpected subclass');
