upgrade all packages for full support of null-safety

Hi @LiquidatorCoder ,

Hope you are all well ! and happy new year !

I was playing with your great project and one thing that was obvious to me is that you should maybe upgrade all packages for full null-safety support

What do you think about that ?

Cheers,

Hey, happy new year! 😁

We are working on Prism v3 which we are building from scratch. It supports full null-safety. You can check it out in v3 branch.
