Sometimes, we want to animate backgroundColor in React Native.

In this article, we’ll look at how to animate backgroundColor in React Native.

How to animate backgroundColor in React Native?

To animate backgroundColor in React Native, we can use the animated value’s interpolate method.

For instance, we write:

import * as React from 'react';
import { View, Animated, Text } from 'react-native';
import Constants from 'expo-constants';
import { Card } from 'react-native-paper';

const c = new Animated.Value(0);

export default function App() {
  React.useEffect(() => {
    Animated.timing(c, {
      toValue: 300,
      duration: 3000,
    }).start();
  }, []);

  const color = c.interpolate({
    inputRange: [0, 200, 300],
    outputRange: ['orange', 'lightgreen', 'yellow'],
  });

  return (
    <Animated.View style={{ backgroundColor: color }}>
      <Text>hello world</Text>
    </Animated.View>
  );
}

to create a new animated value with Animated.Value.

Then we call Animated.timing to create the animation.

We specify the toValue to animate to the value of the inputRange we specify.

And we specify the duration of the animation in milliseconds.

Finally, we specify the color values to animate in the outputRange and set the color as the value of the backgroundColor.

As a result, we should see the color change for 3 seconds when the page loads.
