map<TResult extends Object?> method

@optionalTypeArgs TResult map<TResult extends Object?>({ required TResult fragment(TransactionPartnerFragment value), required TResult user(TransactionPartnerUser value), required TResult telegramAds(TransactionPartnerTelegramAds value), required TResult telegramApi(TransactionPartnerTelegramApi value), required TResult other(TransactionPartnerOther value), required TResult affiliateProgram(TransactionPartnerAffiliateProgram value), required TResult chat(TransactionPartnerChat 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 ...;
}
