getTransactions method
returns histories in the same order as txHashes passed in
Implementation
Future<List<Tx>> getTransactions(Iterable<String> txHashes) async {
var futures = <Future<Tx>>[];
if (txHashes.isNotEmpty) {
peer.withBatch(() {
for (var txHash in txHashes) {
futures.add(getTransaction(txHash));
}
});
}
return await Future.wait<Tx>(futures);
}
