mapOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? mapOrNull<TResult extends Object?>({ TResult? oauth(OAuthCredentials value)?, })

A variant of map that fallback to returning null.

It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case _:
    return null;
}

Implementation

@optionalTypeArgs TResult? mapOrNull<TResult extends Object?>({TResult? Function( OAuthCredentials value)?  oauth,}){
final _that = this;
switch (_that) {
case OAuthCredentials() when oauth != null:
return oauth(_that);case _:
  return null;

}
}
