corona-tracker's Issues

Complete Error Handling

Currently the app doesn't have any error handling !
We want to build a complete error handling solution so that , Whenever we encounter any error/exception, We can show relevant dialog box to user instead of leaving app in a dead state with user having no clue !
Things to cover :

• Exception from APIs
  • Platform Exception
  • Socket Exception
  • Timeout
  • Status Code other than 201
  • Any other exception 🙂
• Error in fetching cached Data
• Other errors that I might encounter while going through the code

Implement Dark Mode

Currently the App supports only one theme (i.e. Light Theme)
My Goal is to a Dark Theme and provide some kind of Switch or Interface to change themes, That will be good for both UI and UX.
Moreover, Animating the page while converting to other theme would be additional benefit for UX.

Tasks to accomplish:

• Implement Beautiful Dark Mode.
• Provide a Switch to change theme.
• Animating the page into other theme ( Like Telegram ).
• Overall good state management and Code separation to accomplish this ( Maybe using Provider).

Build a caching service.

Currently , As soon as the app opens it try to fetch the data from API and if the internet connection is poor or there is no internet connectivity in the device , The app will continue to show the Circular Progress indicators , which is not a great UX , There should be a caching service which should display the old data ( fetched most recently ) and a connectivity checker should notify the user about no connectivity , Moreover it would be nice if we can show the Last Updated status to user !

Tasks:

• Build caching service using Hive
• Fetch data from Local db as soon as app starts
• Fetch data from API in background
• Update the data on screen as well as local db as soon as App receives data from API

Null Safety Migration

Migrate the code base to support Sound NULL Safety.

Migrate to official API for India Data.

Currently, The app is using unofficial API for fetching India Data. I noticed that, API has some kind of ambiguity and it is not showing accurate results.
For example, At the time of opening this issue, No. of total cases of Covid-19 in India already crossed 10M mark while the API is only displaying 8M , This is redundant.

The Goal is to migrate the codebase to use official API that provide correct statistics of India Data.

Current API : https://api.rootnet.in/covid19-in/unofficial/covid19india.org/statewise
New API : https://api.covid19india.org/data.json
