Preview: Migrate package to generic type. Work with List<T> instead of List<String>

[JesusHdez960717]

This PR is a preview, not ready for production yet.

This PR includes migrating the package to work with List<T> instead of List<String>. This enhancement makes it easier to handle more complex objects. The migration of the 'core' of the package is complete (with superficial tests), styling details remain, error handling, some extreme cases and documentation according to the modifications. To simplify and organize the work, the TODO list is left below:

• [X] Migration of the operating logic of the package to work with List<T>.
• [X] Generation of usage examples (in main.dart, also main2.dart for a fully customized example).
• [x] Package style for further customization. (I can't think of any more customizations)
• [x] Error handling.
• [x] Documentation.
• [x] Testing
• [x] Visual example in README

Conflicts are in the identation of the asserts, nothing to worry about for the moment.

Hey @JesusHdez960717 Yeah, no worries about the conflicts for now. Really appreciate your work. Btw I must say, this is really fast work :raised_hands:

Hey, please merge the code, i am using custom dropdown, but i want validator for each dropdown. Please merge ASAP.

[JesusHdez960717]

Hi @jarvesusaram99, I am very happy to know that you are interested in the changes that are being made, unfortunately they are more of a technical preview at the moment, it still needs some improvements and a lot of tests, especially since the entire project has been refactored. So at the moment I don't think the changes will be merged. In any case, if you want to use or test what has been done, you can try the following: 1 - Fork the repo 2 - Do the changes needed, maybe merged the branch generic_type_migration into master (test it first). 3 - In the project dependencies instead of working with:

animated_cutom_dropdown: ^version you are using

use:

animated_cutom_dropdown:
  path: your path to your forked github repo

you can use ref: property if you want to point to something other than master.

BTW, If you use the package in its current state it would be great, you would help us with the testing, and you could report us right here if there are any errors, this would make the deployment much faster

@AbdullahChauhan I belive the changes are ready for a first review on your side. I included in the main.dart the update in the use of the package, with what I thought are most of the use cases covered. Very excited with the progress so far. :satisfied:. I hope you like what has been done. I would like your feedback to make the modifications accordingly.

[AbdullahChauhan]

@JesusHdez960717 Hey, big thanks for this amazing work. I think you've completely transformed the package to next level. Just let me go through all of the new implementation ...

One question: Are you done with the changes? So I can make commits if there's any changes/refactoring required!

[JesusHdez960717]

@AbdullahChauhan it's a pleasure to help. From my part, at least for now, it's over, feel free to change everything you need. I hope when you review it you liked the work. I look forward to your review.
