whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. VoAuthPageKeys? page,
    2. VoAuthPageKeys? previousPage,
    3. bool isLoading,
    4. String? error,
    5. String? phone,
    6. String? email,
    7. String? countryCode,
    8. String? formattedPhone,
    9. SendOtpResponse? sendOtpResponse,
    10. VerifyOtpResponse? verifyOtpResponse,
    )?
)

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( VoAuthPageKeys? page,  VoAuthPageKeys? previousPage,  bool isLoading,  String? error,  String? phone,  String? email,  String? countryCode,  String? formattedPhone,  SendOtpResponse? sendOtpResponse,  VerifyOtpResponse? verifyOtpResponse)?  $default,) {final _that = this;
switch (_that) {
case _AuthFlowState() when $default != null:
return $default(_that.page,_that.previousPage,_that.isLoading,_that.error,_that.phone,_that.email,_that.countryCode,_that.formattedPhone,_that.sendOtpResponse,_that.verifyOtpResponse);case _:
  return null;

}
