Migrate the package to null safty

[mohamad97-alhomsi]

your flutter package "flutter_xlider" has many likes and usages and it has very popularity on pub.dev as you know
so it's a good value for you to migrate to null safety to keep numbers rising
I was using this package in my apps and it's very easy to use but now i upgraded flutter to 2.5.2 and I need to migrate my code

It would be great if I could update this library to null safety, I have also updated my project and this is the only library that unfortunately does not comply with the update.

Hi man, dont know if is going to be useful for you but just in case, you can do:

flutter_xlider:
    git:
      url: https://github.com/Ali-Azmoud/flutter_xlider

in your pubspec.yaml, I just saw the repo is updated with null safty
