flutter_vless

Federated Flutter plugin for VLESS, VMESS, Trojan, Shadowsocks, and SOCKS on Android, iOS, macOS, and Windows.

This package exposes a small Dart API for parsing share links and subscriptions, generating Xray configs, and starting either proxy-only or VPN/tunnel mode through platform backends.

The package is open source and free to use, with Android, iOS, macOS, and Windows support included out of the box. The longer guides live under doc/. For long-form docs, see the documentation link in pubspec.yaml.

At A Glance

Platform	Mode	Notes
Android	VPN, proxy-only	`blockedApps` is supported. Emulator support is split into a separate package.
iOS	VPN, proxy-only	Real device required for packet-tunnel testing. App Group and Network Extension are required.
macOS	VPN, proxy-only	Packet Tunnel setup is required. See the macOS architecture notes for route and DNS details.
Windows	VPN, proxy-only	Xray must be available locally. Admin rights may be required for tunnel mode.

Key Capabilities

Android 16KB page size support for modern builds.
Swift Package Manager support for iOS and macOS integration.
Separate Android emulator package for x86_64 emulator targets.
Share-link, subscription, raw JSON, Clash YAML, and sing-box import paths.
Proxy-only mode and VPN/tunnel mode.
Runtime delay checks and status tracking.
Typed Xray config helpers for more explicit advanced configuration.

Try The Example First

The example app is the quickest way to verify platform setup before copying the plugin into your own project.

cd example
flutter pub get
flutter run -d android
flutter run -d ios
flutter run -d macos
flutter run -d windows

iOS needs a signed real device for VPN mode, macOS needs the Packet Tunnel setup, and Windows needs example/windows/xray/xray.exe.

Installation

dependencies:
  flutter_vless: ^1.1.0

Then run:

flutter pub get

If you need the Android emulator binaries, add the emulator package as well:

flutter pub add flutter_vless_android_emulator

Quick Start

import 'package:flutter/foundation.dart';
import 'package:flutter_vless/flutter_vless.dart';

final flutterVless = FlutterVless(
  onStatusChanged: (status) {
    debugPrint(
      'status=${status.state} connection=${status.connectionState.name} '
      'delay=${status.duration}s',
    );
  },
);

Future<void> connect(String shareLink) async {
  final parsed = FlutterVless.parse(shareLink);
  final config = parsed.getFullConfiguration();

  await flutterVless.initializeVless(
    providerBundleIdentifier: 'com.example.myapp',
    groupIdentifier: 'group.com.example.myapp',
  );

  if (await flutterVless.requestPermission()) {
    await flutterVless.startVless(
      remark: parsed.remark,
      config: config,
    );
  }
}

For proxy-only mode, set proxyOnly: true in startVless() and skip the VPN permission step on the paths that do not require a tunnel.

startVless() and getServerDelay() validate that the provided config is a well-formed Xray JSON object before the native layer sees it.

Supported Inputs

FlutterVless.parse() and FlutterVless.parseMany() support:

vmess://
vless://
trojan://
ss://
socks://
raw Xray JSON
base64 subscription payloads
Clash YAML
sing-box JSON

Use parse() for a single share link or a raw config, and parseMany() when you want to keep every supported profile from a subscription payload.

Advanced Usage

The parsed URL objects expose low-level Xray maps for advanced configuration work, including inbound, routing, log, and stream settings. That is intentionally powerful, but it is also intentionally low-level.

If you want a typed config builder instead of mutating maps, see lib/url/xray_config_model.dart and lib/url/xray_config_validator.dart. Those helpers are useful when you want to construct or validate a config before turning it into JSON.

If you need to edit the runtime config, start with Configuration Guide and Architecture Notes.

Example App

The bundled example app shows clipboard import, routing edits, proxy-only mode, and status tracking:
