How to fix Parsing error: Unexpected token?

I am trying to change my text color but I keep on getting Parsing error: Unexpected token as an error but don't know why can someone point out where my error is and how I would be able to fix that?

This is the code:

import React from 'react';
import react, { Component } from 'react'
import { Plateform, StyleSheet, view,text } from 'react-native';
**Here is where I am trying to change the text color everything seems to be in place but I keep on getting that unexpected token error?**
function Header() {
  return (

  );
}
export default Header extends Component;
./src/components/header.js
Error which I am getting is:
  Line 10:78:  Parsing error: Unexpected token
     return (
