Stay tuned for the second part where we will look at how to implement page transition animations.During our visit, we got to chat with the departmental leads of a number of areas that make LAIKA films possible, from costumes, to puppet fabrication, to rigging, and production design. You can check the final source code for this part of the series on its own branch ( part1). Specifically, we haven’t covered:īe sure to check out the docs if you want to learn about those. We haven’t actually covered all the animation functions that the Animated library provides. But that’s the price we have to pay for having finer control over how the animations will proceed. This is because it doesn’t come with components that allow you to easily implement even the most basic types of animations. As you have seen, implementing animations in React Native is very code-heavy. That’s it! In the first part of this series, you’ve learned how to implement basic animations using React Native’s Animated API. If you want that, then there’s the stagger method. The sequence method doesn’t really allow you to specify the delay between each animation. Of course, you can use the same method that we did earlier with the width animations wherein we added a delay setting. Another difference is that we only start the sequence animation itself, not the individual animations inside it. In this case, we’re only using timing animations, but you can actually mix in spring and decay. The sequence method accepts an array of animations. Here’s what that looks like in code:īreaking down the code above, first, we reset the individual animated values, then we start the sequence animation. So you’re essentially wrapping the entire contents of the Card component with Animated.View. The next step to implement the animation is to set the animated style and render an animated version of the component. This ensures that the animation is as smooth as possible. The animation library will automatically figure out anything in between the numbers you specified. Note that we only need to specify a sample for the input and output ranges. And by the time the animation reaches its peak, we want it to be 20% bigger. This means that when the animation gets halfway through its peak, we want to scale the component so it’s 10% bigger than its original size. 1 means it’s the same as its original size because any integer that you multiply by 1 will always be equal to itself. The outputRange in this case refers to the scale factor of the component. This is one of the values we’ve specified in the inputRange, and the corresponding outputRange value for that is 1. We’ve already initialized the animated value to 0. When I said “maps to one another”, I mean this: On the first part of the series, here’s what the final output is going to look like: We will be adding the animations mentioned above as we go along. Throughout the whole series, we’re going to build just a single app. But I’ll let you handle the modifications required to get the app running. If you’re using Expo, you can also follow along as this tutorial doesn’t require the use of any native modules. I also assume that your computer is set up for React Native development. Things like object destructuring and spread operator. This tutorial assumes that you have a working knowledge of the following concepts:Īside from that, you should also be familiar with some ES6 features. In order to follow this tutorial, you must have basic knowledge of React and React Native. How to implement gesture animations when users interact with UI elements.How to implement transition animations when users navigate from one page to another.How to implement basic animations such as scale, spring, and transform.In each part, you will learn the following: In this series, we’ll be taking a look at how we can implement animations in a React Native app. This is through the use of meaningful transitions when hiding or showing UI elements. Most importantly, animations can be used to teach the user how to interact with the app. At the same time, it can also be used to inform the user of the operation’s status. Whenever the app needs to perform a long operation, animations can be used to entertain the user. We will be using react native to implement animation. Animations bring the app to life through the use of movement. Animations provide users with a clear feedback when they’re interacting with the UI elements in the app. Animations are an important part of the user experience, especially for mobile apps.
