null safety added to the project

[VaishnaviSood]

Migrated the dependencies to null-safety (adobe_xd and razorpay_flutter are not compatible with null safety which caused problems). So now the project is not sound null safe. It is a type of mixed version. I thoroughly checked the code for non-nullable and nullable types and edited the code accordingly. If there is any issue regarding it, please inform..
Closes #64

@VaishnaviSood Was there a requirement to update the environment SDK? And can you attach a gif of the checkout window on the cart screen, so that I can verify that Razorpay is still working along with the Adobe XD.

@VaishnaviSood do response whenever you can because I would like to merge this PR as soon as possible.

Firstly sorry for the late reply... and yes it was a requirement to update the SDK as the latest version of Dart supports null safety.
Razorpay is working fine.....but I guess the only problem now is that app would not run...we have to run the app by command 'flutter run --no-sound-null-safety', because the app is not sound null safe.
I hope the video would demonstrate working of razorpay.

Okay @VaishnaviSood thanks for the update, let the PR exists until we somewhat finalise this app. You can create the null safety issue in these plugins as I told you earlier. And you can proceed with other issues. I'll let you know when to update this PR.

@VaishnaviSood I am converting this PR to draft. I'll try to release the null safety version of Razorpay as soon as possible to make the project sound null safe.

ohkay!...That's good...but the adobe_xd package also did not have a null safe version. If you could do something about that. And do inform me when its all done..I'll make the required changes

I think we can remove the adobe_xd, I'll check it and update you soon.
