whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String id,
    2. String deviceInfo,
    3. String ipAddress,
    4. String createdAt,
    5. String expiresAt,
    )?
)

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 deviceInfo,  String ipAddress,  String createdAt,  String expiresAt)?  $default,) {final _that = this;
switch (_that) {
case _AuthSession() when $default != null:
return $default(_that.id,_that.deviceInfo,_that.ipAddress,_that.createdAt,_that.expiresAt);case _:
  return null;

}
}
