Hi @Merrick17, Would you mind if show me your full code ?!. I guess you didn't set network is testnet. Default network is mainnet

Hi @Merrick17,
Here are how can using testnet in this lib:

// Generate a testnet P2PKH address from <pubkey>

import 'package:bitcoin_flutter/src/models/networks.dart' as NETWORKS;
import 'package:bitcoin_flutter/src/payments/p2pkh.dart' show P2PKH;
import 'package:bitcoin_flutter/src/payments/index.dart' show PaymentData;

final address = new P2PKH(data: new PaymentData(pubkey: <pubkey>), network: NETWORKS.testnet).data.address;
