Add continuous integration

[Monik09]

Adding continuous integration using github actions to check if the app is correctly building or there is an issue in it so that no PR is merged before correcting the error.

This issue will help us remove issues during final build of the app.

If this issue is good to go, I will definitely like to work on it.

@singhalpranav22 Do we need analyzing option too in the CI. With this option, we can analyze our flutter app for any issues(including formatting issues) and will fail the build if there is some error. This option will be followed by automatic building of apks for easy viewing the progress.
So should I add this too?

@Monik09 Yes, seems alike a good feature. Go on.
