whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String? userId,
    2. String? token,
    3. String? email,
    4. String? newPassword,
    5. String? confirmPassword,
    6. String? currentPassword,
    )?
)

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? userId,  String? token,  String? email,  String? newPassword,  String? confirmPassword,  String? currentPassword)?  $default,) {final _that = this;
switch (_that) {
case _PasswordRequestModel() when $default != null:
return $default(_that.userId,_that.token,_that.email,_that.newPassword,_that.confirmPassword,_that.currentPassword);case _:
  return null;

}
}
