The welcome screen of your app can break or make the image of your business. So, make sure it is as best as other features.
Imagine your app appears in the search result of your potential customer. They click the website link with much excitement. But only get navigated to a single screen with a plain white background and a sign-in button. After seeing your screen, you can expect only one expression “how boring!” Consequently, they will immediately close your site and go to the next one. You just lost a business.
Sounds scary, right? If you do not want this to become a reality, get an attractive welcome screen for your app. To be precise, your screen should be multi-colored with smooth animations in the background. And you can achieve this all effortlessly in React Native. Also, it is crucial to hire a React Native development company in New Jersey with relevant skills and experience in the field.
- A guide to building a good-looking welcome screen with React Native
In this tutorial, we will use some building blocks to define AppIntroSlider class, such as:
- Swiping behavior
- Rotation layout logic
- Animation logic
- Pagination dots
In addition to this, we need some supporting types, like:
- Slides – When it comes to a Slide, it comprises swipe-able components, including title, subtitle, and icon.
- State – We need State to track the index, width, and height of the slide. They are necessary because each orientation and screen size has a different layout.
In this step, we need to define AppIntroSlider class. But it requires defining some variables, like:
- flatListRef includes slides as a horizontally scrollable list. It allows users to look at a particular item at a time.
- backgroundImageAnim helps you track a Slide you are currently on.
Now, we will render Slides as part of a FlatList, which is a horizontally scrollable list. Also, we will use props like onMomentumScrollEnd and on Layout. The former works once a scroll view is finished moving, whereas the latter ensures layout changes.
4. Dealing with Slide changes
As a user scrolls the Flat list to another Slide, handleMomentumScrollEnd comes into the picture. At the same time, the State will undergo an update to recognize the current index of the Slide.
5. Get background animations
Another way to make your welcome screen looks appealing is by triggering background animation upon any changes. But the animation should be smoother and faster.
For example, we can use backgroundImageAnim. It changes the current index value in 700 milliseconds. Besides this, we can use the native driver. All we need to do is set up useNativeDriver: true.
6. Pagination Dots
Pagination dots refer to three dots indicating your current Slide and helping you move to the next Slide by tapping on it. When a user presses each dot, it stimulates goToSlide. As a result, it updates the activeIndex value and triggers scrollToOffset.
Establishing the layout
Understandably, you want your welcome screen to work perfectly on all devices and orientations. It is advisable to use react-native-device-info. It can help find where the device is a tablet or landscape orientation.
