React-Native Front end developement

There is a need to modify the current front end application :
- Design a button A following some simple style requirements
- Once a button A has been clicked the text of the button shall change from one value to another
- The button A shall blink depending on a certain state (first press blink second blink stop)

- Design a button B (following a simple style already implemented)
- The action (onpress will be implemented by myself)

It's a first step of continues project
