The WorldHealthOrganization/app repository is an official COVID-19 mobile application developed by the World Health Organization (WHO). It aims to provide accurate and timely information about the COVID-19 pandemic to users worldwide. The app is built using Flutter, allowing for cross-platform development for both iOS and Android devices.

Pros

• Provides official, reliable information directly from the World Health Organization
• Cross-platform development using Flutter, ensuring consistency across iOS and Android
• Open-source project, allowing for community contributions and transparency
• Supports multiple languages for global accessibility

Cons

• Limited functionality beyond providing information (e.g., no contact tracing or symptom tracking)
• Requires frequent updates to maintain current information about the pandemic
• May face challenges in adoption due to competition from other COVID-19 apps
• Potential privacy concerns related to data collection and usage

Code Examples

// Example of fetching COVID-19 statistics
Future<CovidStatistics> fetchCovidStatistics() async {
  final response = await http.get('https://api.who.int/covid-19/statistics');
  if (response.statusCode == 200) {
    return CovidStatistics.fromJson(json.decode(response.body));
  } else {
    throw Exception('Failed to load COVID-19 statistics');
  }
}

// Example of displaying a localized message
Text(
  AppLocalizations.of(context).translate('stay_home_message'),
  style: Theme.of(context).textTheme.headline6,
)

// Example of implementing a custom WHO-themed button
class WHOButton extends StatelessWidget {
  final String text;
  final VoidCallback onPressed;

  WHOButton({@required this.text, @required this.onPressed});

  @override
  Widget build(BuildContext context) {
    return ElevatedButton(
      child: Text(text),
      style: ElevatedButton.styleFrom(
        primary: WHOColors.blue,
        onPrimary: Colors.white,
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(8),
        ),
      ),
      onPressed: onPressed,
    );
  }
}
