Setting Up Your Environment If you haven’t already set up a React project, you can use Create React App: Step 2: Create a Wave Component We will create a component that renders a wave using SVG. Let’s create a new file called Wave.js in the src folder. 1. Create Wave.js Step 3: Integrate Wave Component in App Now, let’s use the Wave component in App.js and add some basic state management to animate it. 1. Update App.js Step 4: Add Basic Styles Add some basic styles in App.css to make it look nicer: Step 5: Run Your Application Start your application using: Summary You now have a simple React application that features a wave animation! Users can control the amplitude, frequency, and speed of the wave through input fields. This serves as a basic introduction to creating animations with SVG in React. Feel free to experiment with different values and enhance the app with more features, such as color customization or saving configurations!

Setting Up Your Environment Make sure you have Node.js and npm installed. You can set up a new React Native project using Expo, which simplifies the process: Step 2: Create Basic Components We’ll create two main components: ItemList and AddItem. 1. Create ItemList.js In the components folder (create it if it doesn’t exist), create a new file called ItemList.js: 2. Create AddItem.js Now create another file called AddItem.js: Step 3: Main Application Component Now, let’s connect everything in App.js. Step 4: Run Your Application Start your application using Expo: This will open a new tab in your browser where you can run the app on an emulator or your physical device using the Expo Go app. Step 5: Explore and Enhance You now have a basic React Native application! You can enhance it by adding features like: Summary In this tutorial, you created a simple React Native app that allows users to add items to a list. You learned how to manage state and create reusable components in React Native.

How does the alignItems flexBox property works?
You can think of alignItems as justifyContent behaviour for cross-axis. Cross-axis in the case if React native is the horizontal axis. CSS alignItems property sets the alignSelf value on all direct children as a group. In Flexbox, it controls the alignment of items on the cross-axis. By default, the cross axis is horizontal in the case of React native. We can use this property to layout elements in the flex container. The alignItems property supports following values: stretch|center|flex-start|flex-end|baseline|initial|inherit; Let me explain align items values:
How does the justifyContent flexBox property work?
JustifyContent property aligns the flexible container’s items when the items do not use all available space on the main axis. By default, the main axis is vertical in the case of React native. This means justifyContent property aligns child elements of flex parent vertically in React native. We can use this property to layout elements in a flex container. JustifyContent supports the following values: flex-start|flex-end|centre|space-between|space-around|initial|inherit; It also applies some control over the alignment of items when they overflow the line. Let me explain JustifyContent’s values:
What are the differences between Flexbox in the browser and Flexbox in React Native?
CSS Flexbox is used to design responsive layouts easily, without relying on float or position CSS properties, which can be cumbersome. Introduced in CSS3, Flexbox ensures consistent layouts across different screen sizes. In React Native, you typically use a combination of flexDirection, alignItems, and justifyContent to achieve the desired layout. There are some differences in the default values of certain flex-based CSS properties between React Native and web browsers: Flexbox properties like alignItems and justifyContent help position elements: These properties allow for easy and flexible layout designs, ensuring responsive and adaptive UIs across different devices.
How do you handle element size in React Native?
React Native follows the box model concept of CSS, where the size of an element is determined by its content, padding, border, and margin. The simplest way to set an element’s size is by specifying the width and height CSS properties. In React Native, all dimensions are unitless and represent density-independent pixels, ensuring consistent element sizes across different screen sizes when using fixed values. However, if you need to set dimensions as a percentage, React Native does not directly support this. Instead, it provides the Dimensions module, which gives the width and height of the mobile device. This information can be used to dynamically set an element’s style at runtime, allowing for responsive design by calculating percentage-based dimensions. Below is an example of how to use the Dimension module from React native: Importing module from React Native: import { Dimension } from ‘react-native’; Figure out the width and height of the device: const deviceWidth = Dimension.get(“window”).width; const deviceHeight = Dimension.get(“window”).height; Calculate the style value: Width: deviceWidth*<percentageValue>/100 But the simplest way is by setting width and height CSS for an element.
What is the state in the React component?
The state is another way apart from props by which we can modify a React component. React component’s state value changes in the life cycle of the component, unlike props. We should not directly change the state value of the react component. React framework gives the setState method by which the state of a component should be changed. The above code is an implementation of a counter component. This component has a state count whose value is changed by clicking on the plus (+) and minus (-) buttons. As the state count of this component is changing the number displayed on UI is also changing. Whenever we create any component in React, first we divide the screen in the component and then decide what state a component should have. The beauty of this component is that it is an independent component and can be used anywhere in the application. That is how we make several fully functional components in React to build the complete application.
How do you integrate third-party libraries with React Native?
Integrating third-party libraries involves: These steps ensure the library is correctly integrated and functional within the React Native app.
What are Native Modules, and how do you use them in React Native?
Native Modules allow integrating custom native code into a React Native app: Native Modules provide flexibility to leverage platform-specific features and optimize performance.
