  showDialog(context: context,builder: (context) => _onTapImage(context)); // Call the Dialog.
  
  _onTapImage(BuildContext context) {
      return Stack(
        alignment: Alignment.center,
        children: <Widget>[
          Image.network('https://via.placeholder.com/150',fit: BoxFit.contain,), // Show your Image
          Align(
            alignment: Alignment.topRight,
            child: RaisedButton.icon(
                color: Theme.of(context).accentColor,
                textColor: Colors.white,
                onPressed: () => Navigator.pop(context),
                icon: Icon(
                  Icons.close,
                  color: Colors.white,
                ),
                label: Text('Close')),
          ),
        ],
      );
    }
