+# Covid-19 Mobile App
+
+Mobile app to get information about covid-19 cases.
+Link to the API used: https://documenter.getpostman.com/view/8854915/SzS7R6uu?version=latest
+
+Before runnning the application, run the following command:
+```
+flutter pub get
+```
+
+You can then run the project with the following command:
+```
+flutter run
+```
+
+Just to ensure that the app works perfectly, add the following permission in ```AndroidManifest.xml``` file:
+
+```
+<uses-permission android:name="android.permission.INTERNET" />
+```
+
+By default the app shows Corona Virus cases in India on the home page. You can change the country name in variable ```url2``` to show the cases in other coountries or maybe get the location of the user and show accordingly.
+
+The packages used in this project are as follows:
+
+1. number_display - to display data in a width-limited component. For eg: it converts 2500000 to 2.5M
+
+2. http - to send http requests to the API
+
+3. bezier_chart - to visualize the received data from the API
+
+4. folding_cell - to display a foldable cell to view details(total deaths, today cases, etc.). This foldable cell is present in 'Affected Countries' page
+
+
+Images are present in the ```assets``` folder
+
+
+Files present in this project along with their purposes are given below:
+
+```resources/fetch_data_functions.dart``` - contains functions to fetch data from the api(NovelCOVID API).
+
+```screens/home.dart``` - shows Covid-19 cases of the whole world(all coutries together) and includes visualization of the cases in India(you can change the country by changing the url).
+
+```screens/countrylist.dart``` - shows Covid-19 cases, country wise, in the form of a list. Each cell in the list is foldable. Upon expanding the cell, more info is shown.
+
+
+```screens/searchCountry.dart``` - similar to ```screens/countrylist.dart``` but here user can also search.
+
+```widgets/drawer.dart``` - contains the side drawer code
+
+```widgets/foldable_cell_widgets.dart``` - contains reusable front, inner top and inner bottom widgets of the foldable cell that are used in ```screens/countrylist.dart``` and ```screens/searchCountry.dart```.
+
+```widgets/graph.dart``` - contains the code for building the graph.
+
+```widgets/info_card.dart``` - contains the code for displaying rounded retangular cards on the home page.

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
