        this.country = country;
      });
    });
  }
  
    @override
  Widget build(BuildContext context) {
    // To simply launch the country picker
    // use countryPicker.launch(context)
    // to forcefully dismiss use countryPicker.dismiss()
    // simple example could be
    return GestureDetector(
      child: AssetImage(country.flagUri, package: 'ola_like_country_picker'),
      onTap(){
          countryPicker.launch();

      setState(() {
        this.country = country;
      });
    });
    CountryListView clv = CountryListView(showFlag:false); //own version of CountryListView
    c.setCountryListView(clv);
    ...
    ...
    // Call c.launch(context) in GestureDetector() or other listeners 
    ...
