Example Usage

Connecting to a Pactus node and retrieving blockchain information:

import 'package:flutter_pactus_grpc/flutter_pactus_grpc.dart';
import 'package:grpc/grpc.dart';

Future<void> connectToPactus() async {
  // Establish a gRPC channel
  final channel = ClientChannel(
    'localhost',
    port: 50051,
    options: const ChannelOptions(
      credentials: ChannelCredentials.insecure(),
    ),
  );

  // Initialize the blockchain service client
  final client = BlockchainServiceClient(channel);

  try {
    // Fetch blockchain information
    final response = await client.getBlockchainInfo(BlockchainRequest());
    print('Blockchain Height: ${response.height}');
  } catch (e) {
    print('Error: $e');
  } finally {
    // Clean up and close the channel
    await channel.shutdown();
  }
}

void main() {
  connectToPactus();
