Great! Thank you for opening this issue.

Ok, first a few things:

• Read the contribution guidelines in readme. Package name needs to be in a certain way so that all apps use same pattern.
• The example app as you describe needs to be built in a way it is easily consumable. i.e split your code into files. Having one single main.dart file with a lot of nesting is not readable and also hard to review.
• Make sure you are using the latest version of Flutter.
• The libs you want to use can you list them down here? So I can take a look at what they are.
• Question: Is there a requirement for using the API? If so what are those?

I have changed the package name according to the guidelines. The package name in the case of this example app is github.nisrulz.

I have split the code into different files. I will document the code and also use understandable variable names as much as possible. I have also formatted the code in every file.

I am using the latest version of flutter viz. v 1.22.0

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 the 'Affected Countries' page.

There is a requirement to use the API because without the API, it is not possible to get the data(total deaths, today deaths, total cases, active cases, etc.).

Looks good to me.

I think you are good to open the PR. Make sure you branch from develop, add all your changes and then open your PR against develop.

I have opened the PR. Please if you could review it.
