Add link to swipe detector package for flutter in UI section.

Not sure how to deal with this package it's very specific.
Can you tell us more on why it's required ? why this impl and no more GestureDetector behavior ?
Thanks

In my project I wanted a way to detect swipes, which I had to build by using and customizing values from GestureDetector. So I wrapped the code I wrote into a package for anyone looking for similar functionality. It saves time and effort, which is what a library is supposed to do.

Added Slidable package to fully manage the swipe.

If you have others packages that you would like to submit you are very welcome.

Alright, but what swipedetector provides is very different from slideable. In android you would detect swipe directions using onTouchEvent, swipedetector is a substitute of that for Flutter.

Yeah I understand this is an abstraction of the Swipe effect but this is a very specific case.
I try to curate the list to have only the most commons use cases and I cannot add all the resources.
The list doesn't reflect on the quality of the package only ones that cover the most common problems.
I may even have to use your package in one of my current project !

Ok changed my mind, this is really advanced but in specific design case it will help.

Thanks very much.
I am developing 2 more libraries on top off http package that target a very common problem.
Will let you know once done.
