Sui gRPC Flutter

High-performance gRPC client for Sui blockchain in Flutter applications.

https://docs.sui.io/concepts/grpc-overview

This Flutter plugin is in active development and may introduce breaking changes. Contributions from developers who want to help shape the project at this stage are welcome. Feedback, bug reports, and pull requests are greatly appreciated as the project moves toward a stable release.

Features

• 🚀 High-performance gRPC protocol
• 🔒 Type-safe Dart models
• 🌐 Multi-network support (Mainnet, Testnet, Devnet)
• 🔄 Real-time subscriptions
• 📱 Cross-platform (iOS, Android, Web, Desktop)

Usage

🔌 Connecting to Sui Network

This plugin simplifies integration with the Sui network by leveraging the latest gRPC protocol support.

// Connecting to devnet
final client = SuiGrpcClient.fromNetwork(SuiNetwork.devnet);

// Connecting to testnet
final client = SuiGrpcClient.fromNetwork(SuiNetwork.testnet);

// Connecting to mainnet
final client = SuiGrpcClient.fromNetwork(SuiNetwork.mainnet);

Future<void> _testConnection() async {
  final isHealty = await _client.isHealty();
  log(isHealty, name: '_testConnection');
}

🎣 Querying the Sui Blockchain

Future<void> _testGetObject() async {
  final objectId = _objectIdController.text;
  if (objectId.isEmpty) return;

  final object = await _ledgerService.getObject(
    ObjectId.fromHex(objectId),
    fieldMask: FieldMask.objectFull,
  );

  if (object != null) {
    log(object, name: '_testGetObject');
  }
}
