Usage

flutter pub add wireguard_flutter

Initialize

Initialize a wireguard instance with a valid name using initialize:

final wireguard = WireGuardFlutter.instance;

// initialize the interface
await wireguard.initialize(interfaceName: 'wg0');

and declare the .conf data:

const String conf = '''[Interface]
PrivateKey = 0IZmHsxiNQ54TsUs0EQ71JNsa5f70zVf1LmDvON1CXc=
Address = 10.8.0.4/32
DNS = 1.1.1.1


[Peer]
PublicKey = 6uZg6T0J1bHuEmdqPx8OmxQ2ebBJ8TnVpnCdV8jHliQ=
PresharedKey = As6JiXcYcqwjSHxSOrmQT13uGVlBG90uXZWmtaezZVs=
AllowedIPs = 0.0.0.0/0, ::/0
PersistentKeepalive = 0
Endpoint = 38.180.13.85:51820''';

For more info on the configuration data, see the documentation with examples.

Connect

After initializing, connect using startVpn:

await wireguard.startVpn(
  serverAddress: address, // the server address (e.g 'demo.wireguard.com:51820')
  wgQuickConfig: conf, // the quick-config file
  providerBundleIdentifier: 'com.example', // your app identifier
);

Disconnect

After connecting, disconnect using stopVpn:

await wireguard.stopVpn();

Stage

Listen to stage change using vpnStageSnapshot:

wireguard.vpnStageSnapshot.listen((event) {
  debugPrint("status changed $event");
});

Or get the current stage using getStage:

final stage = await wireguard.stage();

The available stages are:

Code	Description
connecting	The interface is connecting
connected	The interface is connected
disconnecting	The interface is disconnecting
disconnected	The interface is disconnected
waitingConnection	Waiting for a user interaction
authenticating	Authenticating with the server
reconnect	Reconnecting the the interface
noConnection	Any connection has not been made
preparing	Preparing to connect
denied	The connection has been denied by the system, usually by refused permissions
exiting	Exiting the interface

Supported Platforms

	Android	iOS	macOS	Windows	Linux
Version	SDK 21+	15.0+	12+	7+	Any

Windows

On Windows, the app must be run as administrator to be able to create and manipulate the tunnel. To debug the app, run flutter run from an elevated command prompt. To run the app normally, the system will request your app to be run as administrator. No code changes or external dependencies are required.

Linux

Install dependencies

The required dependencies need to be installed: wireguard and wireguard-tools.

On Ubuntu/Debian, use the following command to install the dependencies:

sudo apt install wireguard wireguard-tools openresolv

For other Linux distros, see this.

Note

If openresolv is not installed in the system, configuration files with a DNS provided may not connect. See this issue for more information.

Initializing

When wireguard.initialize is called, the application will request your user password ([sudo] password for <user>:). This is necessary because wireguard must run as a root to be able to create AND manipulate the tunnels. This is true for either debug and release modes or a distributed executable.

Caution

Do not run the app in root mode (e.g sudo ./executable, sudo flutter run), otherwise the connection will not be established.

FAQ & Troubleshooting

Linux error resolvconf: command not found

On Linux, you may receive the error resolvconf: command not found. This is because wireguard tried to adjust the nameserver. Make sure to install openresolv or not provide the "DNS" field.
