Tutorial On How To Implement React Native Animations Using Animated API
Introduction
Do you guys know what makes users engage with your application? Yes, Let me tell you. Animations - Yes Animations play significant roles when it comes to engaging users with your applications. Animations are a crucial part of UX. If you want a better interaction experience from your users, your Animation must be powerful and unique. It makes user engagement even smoother with your application.
The unique features of your Animation like its various transitions to present elements make it more enjoyable for users.
You might have heard about the implement React Native Animations using an animated API, and I know you are searching for it. Being a React native programmers, I have something for you. Today I will show you a step-by-step tutorial on adding React Native animations from scratch.
Tutorial Goal: First Let’s Learn to Implement React Native Animations
Before going to learn, I want you to watch this video. This is the final output.

Our main objective is to build an animated value and later on we can use it for various components.
In today's tutorial, I will discuss the below types of React Native Animation.
- Animated.parallel()
- Animated.timing()
- Animated.sequence()
- Animated.spring()
Working with React Native Animations
So, Let’s start the animation by using the Start() - when the animation task is completed, It takes a completion callback.
Using start function with Animated.timing() :-
Animated.timing(value,{}).start()
Animated.timing() - will be a work of two parameters - an object and a value. Objects can take values like durations, value, opacity, etc.
If you want to use another parameter, you will use useNativeDriver. You know how it works? Before the start of animations, It send everything to native code about animation.
Use this in the animation configuration:
useNativeDriver: true
I want to inform you that various React Native Animatable components are available and only those can be animated.
- Animated.Image
- Animated.SectionList
- Animated.View
- Animated.Text
- Animated.ScrollView
- Animated.FlatList
Steps to Quickly Add Animations in React Native App
Let’s look at the first steps
1. Creating a React Native App
You can use react native app by using:
react-native init Animation
2. Installing dependencies for Navigation
Now for navigating screens you need to install stack navigation:
3. Creating Components
Now you will have to create some animation screens like:-
- Fade Animation
- Spin Animation
- Scale Animation
- Spring Animation
- Parallel Animation
- Sequence Animation
Let's understand the coding structure of all the components one by one.
Fade Animation
It will create an animation at your image components, and make it fade in on render.
You need to create Animated.Value(), as you have to make the component animatable every time.
const Fade= new Animated.Value(0)
You will call Animated.timing() in useEffect(). Here Animated.Timing() is used to change the output for a specific input value with a certain time.
As we already know Animated.Timing() takes three arguments, first is value & its need to be updated. The second is object and third one is useNativeDriver: true, which I already explained.
Spin Animation
Based on the output degree values, Spin Animation spins and rotates components.
Interpolation: With the help of interpolation you can change rotation, colors amd scale the animation component.
Scaling Animations
It used to grow and expand the components.
Spring Animation
It’s like how spring looks when it’s in motion.
Here Animated.spring() and Animated.timing() take a similar configuration. It used friction and tension instead of duration.
Parallel Animation
Here we have made three different animations parallelly like scale, rotate, and spring.
Rendering Animated components(View and text) on the screen with types:
Sequence Animation
It animates different Animation type configurations one by one after the previous one ends.
Let’s have look on Initializing steps,
Conclusion
This is all I have in my tutorial for you about how to implement React Native Animations using Animated API scratch. Animation is the only key to keep your users engaged with your application and animation will be the reason your users enjoy interacting with your application. If you want to make your animation powerful, contact one of the best React native development company to animate your React Native App. you can take the help from react native development services for building your application strong in the set of animation. I suggest you to Hire React Native Developer at your convenience and get the desired output of animation.
