lookup abstract method

Future<List<Entity?>> lookup(
  1. List<Key> keys, {
  2. Transaction transaction,
})

Looks up the fully populated keys in the datastore and returns either the Entity corresponding to the Key or null. The order in the returned Entitys is the same as in keys.

If a transaction is given, the lookup will be within this transaction.

Implementation

Future<List<Entity?>> lookup(List<Key> keys, {Transaction transaction});
