If you're installing this in a bare React Native app, you should also follow these additional installation instructions.

import React from 'react';
import { Text, View } from 'react-native';
import { LinearGradient } from 'expo-linear-gradient';

export default class FacebookButton extends React.Component {
  render() {
    return (
      <View
        style={{
          flex: 1,
          alignItems: 'center',
          justifyContent: 'center',
          backgroundColor: 'orange',
        }}>
        // Background Linear Gradient
        <LinearGradient
          colors={['rgba(0,0,0,0.8)', 'transparent']}
          style={{
            position: 'absolute',
            left: 0,
            right: 0,
            top: 0,
            height: 300,
          }}
        />
        // Button Linear Gradient
        <LinearGradient
          colors={['#4c669f', '#3b5998', '#192f6a']}
          style={{ padding: 15, alignItems: 'center', borderRadius: 5 }}>
          <Text
            style={{
              backgroundColor: 'transparent',
              fontSize: 15,
              color: '#fff',
            }}>

          </Text>
        </LinearGradient>
      </View>
    );
  }
}

import { LinearGradient } from 'expo-linear-gradient';

colors
An array of colors that represent stops in the gradient. At least two colors are required (otherwise it's not a gradient, it's just a fill!).
start
An array of [x, y] where x and y are floats. They represent the position that the gradient starts at, as a fraction of the overall size of the gradient. For example, [0.1, 0.2] means that the gradient will start 10% from the left and 20% from the top.
end
Same as start but for the end of the gradient.
locations
An array of the same length as colors, where each element is a float with the same meaning as the start and end values, but instead they indicate where the color at that index should be.
