Hello guys.

In this article, we are creating an app, and this is the first part of the Covid-19 App. In this app we have the following pages.

Global
Home
Covid-19 Search Countries
About us
CovidTabbedPage

Idea: During the COVID pandemic situation all over the world, I got an idea to develop an app which tracks records of the cases by counties and also show safety measures.

In this article, we have a COVID-19 App Global Page and Home Page, In the home page, we add a carousel view and cell view for showing the COVID-19 global data.

I am not going to describe the basic project setup steps here.

So let's design......

Global

In this Global page, we add one carousel and show the global data of COVID-19 like Total Cases, Total Recovery, Total Deaths and Total Active.

GlobalReport.xaml

Home Report

In this Home page, we add the redirecting button for the social app (MyGov Corona) and show the home country (India) data of COVID-19 like Total Cases, Total Recovery, Total Deaths and Total Active.

Now we are creating the ViewModel(HomeViewModel) and binding the data with a view.

HomeViewModel.cs

public class HomeViewModel:BaseViewModel
{
public HomeViewModel { }
#region Properties
private CountryModel country;
public CountryModel Country
{
get { return country; }
set {country = value; RaisePropertyChanged(() => Country); }
}
#endregion
#region Commands
public Command WhatsAppCommand => new Command(() => Device.OpenUri(new Uri("https://api.whatsapp.com/send?phone=919013353535")));
public Command TelegramCommand => new Command(() => Device.OpenUri(new Uri("tg://resolve?domain=MyGovCoronaNewsdesk")));
public Command InstagramCommand => new Command(() => Device.OpenUri(new Uri("instagram://user?username=mygovindia")));
public Command FBCommand => new Command(() => Device.OpenUri(new Uri("fb://group/224193992332793")));
public Command MessengerCommand => new Command(() => Device.OpenUri(new Uri("http://m.me/MyGovIndia")));
#endregion
}

That's it for this article, we will cover more in the next article.
