The default values within the ConnectivityUtils are getting overridden with NULL if initialize is called without values passed through. Also they will get overridden if instance is called and no instance exists.
If not it forces the user to call the following all the time
ConnectivityUtils.initialize(serverToPing: "http://www.gstatic.com/generate_204", callback: (_) => true);

ConnectivityUtils._({String serverToPing, VerifyResponseCallback callback}) { // Change these two lines from: this._serverToPing = serverToPing; this._callback = callback; // TO: this._serverToPing = serverToPing != null ? serverToPing : this._serverToPing; this._callback = callback!= null ? callback: this._callback ; `
