whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. UserProfile? profile,
    2. SupplierProfile? supplierProfile,
    3. Customer? customerProfile,
    4. CommunicationSettings? communicationSettings,
    5. AuthCredentialResponse? auth,
    6. Navigation? navigation,
    )?
)

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(@JsonKey(name: 'profile')  UserProfile? profile, @JsonKey(name: 'supplierProfile')  SupplierProfile? supplierProfile, @JsonKey(name: 'customerProfile')  Customer? customerProfile, @JsonKey(name: 'communicationSettings')  CommunicationSettings? communicationSettings, @JsonKey(name: 'auth')  AuthCredentialResponse? auth, @JsonKey(name: 'navigationActions')  Navigation? navigation)?  $default,) {final _that = this;
switch (_that) {
case _UserResponse() when $default != null:
return $default(_that.profile,_that.supplierProfile,_that.customerProfile,_that.communicationSettings,_that.auth,_that.navigation);case _:
  return null;

}
}
