Create an application with a red button placed in the center of the screen. Upon the user's touch, initiate a pulsating animation where the button grows to n+10 and then shrinks back to n-10 of its original size, maintaining a continuous loop.

Project Overview
Develop an interface featuring a single red button at the screen's center, which pulsates when interacted with.

UI/UX Design and Flow
- Layout: Fullscreen with a centralized button.
- Button: Initial size of 100px x 50px, positioned centrally.
- Interaction: On touch, trigger pulsating animation.

Core Functionality and Logic
- Implement a looping animation that increases the button size by 10 units and then decreases it by 10 units each second.
- Ensure the button remains red throughout the animation and reverts to its original size when untriggered.

Best Practices
- Optimize performance to keep animations fluid.
- Ensure the button remains interactive at any size during its pulsation.
- Test for consistent behavior across varying screen sizes and orientations.

create a red button in the center of the screen.
when the user touches the screen, it start to pulsate. n+10 to its original size,
each second, when it goes t n+10, it stars to go n-10, when it goes n-10,
it starts enlarging again. place it in an forever loop. 

Q: What should be the original size of the button?
A: For example, 100px x 50px

Q: Should there be any color change during the pulsating effect?
A: No, just pulsate
