mapOrNull<TResult extends Object?> method

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

}
}
