Recipe

Initialize

Before start, you have to initialize the OpenVPN plugin.

    late OpenVPN openvpn;

    @override
    void initState() {
        openvpn = OpenVPN(onVpnStatusChanged: _onVpnStatusChanged, onVpnStageChanged: _onVpnStageChanged);
        openvpn.initialize(
            groupIdentifier: "GROUP_IDENTIFIER", ///Example 'group.com.laskarmedia.vpn'
            providerBundleIdentifier: "NETWORK_EXTENSION_IDENTIFIER", ///Example 'id.laskarmedia.openvpnFlutterExample.VPNExtension'
            localizedDescription: "LOCALIZED_DESCRIPTION" ///Example 'Laskarmedia VPN'
        );
    }

    void _onVpnStatusChanged(VPNStatus? vpnStatus){
        setState((){
            this.status = vpnStatus;
        });
    }

    void _onVpnStageChanged(VPNStage? stage){
        setState((){
            this.stage = stage;
        });
    }

Connect to VPN

    void connect(){
        openvpn.connect(config, name, username: username, password: password, bypassPackages: [], certIsRequired: false);
    }

Disconnect

    void disconnect(){
        openvpn.disconnect();
    }

Publishing to Play Store and App Store
