Flutter V2Ray Client Desktop Plugin — V2Ray/Xray & Sing-Box VPN for Windows, macOS, Linux

flutter_v2ray_client_desktop — V2Ray/Xray & Sing-Box VPN for Windows, macOS, Linux

Amir Ziari introduces flutter_v2ray_client_desktop, a premium Flutter plugin enabling V2Ray/Xray and Sing-Box VPN/TUN on Windows, macOS, and Linux. It offers real-time stats, system proxy, and delay tests with a unified API.

Why This Matters

Cross-platform network tools often face fragmentation due to OS-specific configurations. This plugin reduces complexity by abstracting system proxy management, TUN/VPN modes, and protocol parsing into a single Dart API, cutting development time and error-prone manual setup. Misconfigurations in system proxy or TUN modes can lead to downtime or security gaps, costing developers hours in debugging.

Key Insights

• “Xray Core 25.10.15, Sing-Box 1.12.10”: https://dev.to/amirzr/flutter-v2ray-client-desktop-plugin-v2rayxray-sing-box-vpn-for-windows-macos-linux-5h9d
• “Sagas over ACID for e-commerce”: Not applicable (context focuses on networking, not transactional systems)
• “Temporal used by Stripe, Coinbase”: Not applicable (plugin uses Flutter/Dart, not Temporal)

Working Example

import 'package:flutter_v2ray_client_desktop/flutter_v2ray_client_desktop.dart';

final client = FlutterV2rayClientDesktop(
  logListener: print,
  statusListener: print,
);

await client.startV2Ray(
  config: jsonConfig,
  connectionType: ConnectionType.systemProxy,
);

// Stop and disable proxy
await client.stopV2Ray();

final parser = V2rayParser();
await parser.parse('vmess://example.com');
final fullJson = parser.json();

Practical Applications

• Use Case: Build cross-platform VPN clients with TUN/VPN modes and system proxy support
• Pitfall: Forgetting admin/root privileges on Windows/macOS/Linux for VPN mode, causing runtime failures
