whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String id,
    2. String firstName,
    3. String lastName,
    4. String? email,
    5. String? phoneNumber,
    6. String? countryCode,
    7. List<String> permissions,
    )?
)

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 id,  String firstName,  String lastName,  String? email,  String? phoneNumber,  String? countryCode,  List<String> permissions)?  $default,) {final _that = this;
switch (_that) {
case _AuthUser() when $default != null:
return $default(_that.id,_that.firstName,_that.lastName,_that.email,_that.phoneNumber,_that.countryCode,_that.permissions);case _:
  return null;

}
}
