This is huge!

Thanks for the PR. I tested it and it works. There's a small issue where the screen shakes when you touch it or when you lift your finger.

The issue that @satya164 just mentioned is because of this line
https://github.com/react-native-community/react-native-tab-view/pull/740/files#diff-13c90f71216108ed4d0e57b27084346bL291

I used timing and its configs from next line instead of spring , and it worked. But this is not a solution. just a clue to solve the problem.

Ok, I spent many hours to solve this issue and I'm stuck in it.

I figure out I should multiply this._velocityX to -1 in RTL mode for spring animation, but it's get me an error for prop type require. I spent plenty time to solve this but I'm stuck in it.

also I figure out the index calculated and sent to translateX ( in both rtl and ltr ) calculate multi time and for example when I swipe from index 0 to index 1, base on velocity Its maybe plus two time and the calculate value will be 2 in some time.
