VPN
A Flutter plugin that enables apps to access VPN services on Android and iOS.
What is VPN?
Flutter VPN is a plugin that enables Flutter applications to access and manage VPN services on Android and iOS devices. It solves the problem of integrating secure network tunneling into cross-platform mobile apps by providing a unified Dart API that works across both operating systems. The plugin handles platform-specific implementations, allowing developers to add VPN functionality without deep native expertise.
Flutter developers building mobile applications that require VPN connectivity, such as privacy-focused apps, secure communication tools, or corporate apps needing encrypted network access.
Developers choose this plugin because it offers a streamlined, cross-platform solution for VPN integration, eliminating the need to write separate native code for Android and iOS. Its use of established libraries like strongSwan (IKEv2) and NEVPNManager ensures reliability and security.

Use Cases
Best For
- Adding VPN connectivity to Flutter-based privacy or security apps
- Building corporate Flutter apps that require encrypted network access
- Implementing custom VPN clients within a Flutter mobile application
- Creating cross-platform apps that need to tunnel network traffic securely
- Developing Flutter apps that require IKEv2 protocol support on Android
- Integrating VPN features without managing native Android/iOS code separately
Not Ideal For
- Applications requiring support for VPN protocols beyond IKEv2, such as OpenVPN or WireGuard, especially on Android
- Teams seeking a plug-and-play solution without manual native configuration like Gradle edits or Xcode capability enabling
- Projects targeting platforms beyond Android and iOS, such as web or desktop, where VPN functionality is needed
- Use cases demanding advanced VPN features like split tunneling or custom DNS that might not be exposed through the plugin's API
Pros & Cons
Pros
Provides a unified Dart API for both Android and iOS, abstracting platform-specific complexities as described in the README, allowing developers to focus on app features.
Uses the strongSwan library for IKEv2 protocol on Android, ensuring robust encryption and security for VPN tunnels, as highlighted in the key features.
Leverages Apple's NEVPNManager framework for reliable and system-compliant VPN management on iOS, offering seamless integration with Apple's ecosystem.
Downloads pre-built native libraries for Android automatically if missing, simplifying the build process and reducing manual setup steps as noted in the installation guide.
Cons
Requires modifying Android's build.gradle for ABI filters and enabling Xcode capabilities for iOS, which adds complexity and potential for errors during setup.
Only supports IKEv2 on Android via strongSwan; iOS is constrained to NEVPNManager's capabilities, restricting options for other VPN protocols.
VPN connection errors are handled in Swift code and require Xcode for debugging, which can be cumbersome for Flutter developers accustomed to Dart-centric workflows.
Relies on downloading libraries from GitHub releases, which could introduce security vulnerabilities or break if the repository becomes unavailable.
