feat: contributor screen

[shreyas1599]

Partially completes #53

• Added only for github. There were two ways to do this. Either using /repos/:owner/:repo/stats/contributors or /repos/:owner/:repo/contributors. The former could not be paginated which resulted in problems. The only benefit of the former was getting number of additions and deletions on a weekly basis. The latter provides information only about total commits which I hope is enough. Attaching pictures for reference.

Let me know if there are any changes to be made. Thanks.

Great! Sorry for the late response. I'll take a look this weekend

Hi, @shreyas1599 , you could run dartfmt --overwrite lib/**/*.dart to format code, so the CI step would not fail. If you are using IDE like VSCode or Android Studio, the format tool should already be built-in in the Flutter plugin.

Thanks!
