Flutter Android VPN based on OpenVPN Library.
I made it so simple to connect to OpenVPN, everything is setup, all you need to do is do the layouting on this project (i don't recommanded you to create a new project).
Here, i'll show you how to deal with the "connection things"
Connect or Disconnect vpn with single line of code!
...
_vpnStage = NizVpn.vpnDisconnected;
_selectedVpn = VpnConfig(
config: "OVPN CONFIG IS HERE",
name: "Japan",
username: "VPN Username",
password:"VPN Password"
);
...
...
if (_selectedVpn == null) return; //Stop right here if user not select a vpn
if (_vpnStage == NizVpn.vpnDisconnected) {
//Start if stage is disconnected
NizVpn.startVpn(_selectedVpn);
} else {
//Stop if stage is "not" disconnected
NizVpn.stopVpn();
}
...Don't forget to listen your vpn stage and status, you can simply show them with this.
...
//Add listener to update vpnStage
NizVpn.vpnStageSnapshot().listen((event) {
setState(() {
_vpnStage = event; //Look at stages detail below
});
});
...
...
//Add listener to update vpnStatus
NizVpn.vpnStatusSnapshot().listen((event){
setState((){
_vpnStatus = event;
});
})
... Let me be clearer, VPN Stage shows the connection indicator when connecting the VPN
static const String vpnConnected = "connected";
static const String vpnDisconnected = "disconnected";
static const String vpnWaitConnection = "wait_connection";
static const String vpnAuthenticating = "authenticating";
static const String vpnReconnect = "reconnect";
static const String vpnNoConnection = "no_connection";
static const String vpnConnecting = "connecting";
static const String vpnPrepare = "prepare";
static const String vpnDenied = "denied";Note : To change notification's icon, you can go to vpnLib/main/res/drawable and replace ic_notification.png from there!
