map<TResult extends Object?> method

@optionalTypeArgs TResult map<TResult extends Object?>(TResult $default(_UnspeccedGetTrendingTopicsOutput value))

A switch-like method, using callbacks.

Callbacks receives the raw object, upcasted. It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case final Subclass2 value:
    return ...;
}

Implementation

@optionalTypeArgs TResult map<TResult extends Object?>(TResult Function( _UnspeccedGetTrendingTopicsOutput value)  $default,){
final _that = this;
switch (_that) {
case _UnspeccedGetTrendingTopicsOutput():
return $default(_that);case _:
  throw StateError('Unexpected subclass');

}
}
