How to Fade in and out Horizontally from Left to Right in Flutter?

I want to Animate Text in such a way that it fades in and out Horizontally from Left to Right.
But as I'm absolute beginner in Flutter I am not able to do this in Flutter.
I did search as how to achieve this in Flutter but I didn't find the solution.
Please help me how can I do this in Flutter!
