Hey...Can this issue be assigned to me? :)

[himanshusharma89]

@VaishnaviSood I suppose the remote config will take time, so you can work on this in the meantime. Assigning this to you

[VaishnaviSood]

Thanks...I was working on this issue..and saw that some of the dependencies don't support null safety..any help with that?

[himanshusharma89]

@VaishnaviSood You can update those packages to their null safety version, you can check it in the pub.dev

[VaishnaviSood]

Yes..I did that..but two packages (adobe_xd and razorpay_flutter) don't have a null safe version ..so I am unable to update them..so should I proceed without upgrading them?

[himanshusharma89]

Do one thing, proceed with it and create 2 separate issues regarding these plugins:
For AdobeXD: AdobeXD/xd-to-flutter-plugin#103
For Razorpay: razorpay/razorpay-flutter#133

But you might face few issues regarding nullable types, so let me know if you face any.
Also, I just merged a big update in the code base, so make sure to pull it before migrating.

Ohkay!..Thanks :)
