NetworkInfo constructor
NetworkInfo()
Constructs a singleton instance of NetworkInfo.
NetworkInfo is designed to work as a singleton.
Implementation
// When a second instance is created, the first instance will not be able to listen to the
// EventChannel because it is overridden. Forcing the class to be a singleton class can prevent
// misuse of creating a second instance from a programmer.
factory NetworkInfo() {
_singleton ??= NetworkInfo._();
return _singleton!;
}
