Monitor Connection #
The function monitorConnection allows the user to monitor the internet connectivity. After the device connectivity is changed, the function calls another method that pings google for checking whether the internet connectivity is restored or not.

You can also pass a callback function in internetUnAvailable parameter as shown above to perform a certain task when the internet connectivity is changed and the internet is not available.
You can pass another callback function in internetAvailable parameter to perform when internet is available

messengerKey.currentState?.clearSnackBars();
});

Static URL configuration #
The url is maintained in AppConstant. You can change the url to ping a certain url like your backend. If the url is not changed, the app pings the google server.
void main() {
AppConstant.url = "binitkoirala.com.np";
runApp(const MyApp());
}
