How to use react native text input? Handling text input in React Native can be a tricky task, especially for beginners. However, with a little bit of knowledge and practice, it becomes a breeze. In this blog, we will cover everything from basic to advanced techniques for handling text input in React Native. First, let's start with the basics. In React Native, the most commonly used component for handling text input is the  TextInput  component. This component allows the user to enter and edit text. It has a wide range of props that can be used to customize its behavior and appearance. Some of the most commonly used props include: value : The current value of the text input. onChangeText : A function that is called when the text input's value changes. placeholder : The text to be displayed when the input is empty. secureTextEntry : A boolean value that determines whether the text input should hide the entered text (e.g. for passwords). Here's an example of a basic text input...

Understanding State and Props in React Native Functional Components React Native, the popular framework for building mobile applications, allows developers to build both functional and class-based components. In this blog, we will be discussing the concepts of state and props in functional components. States in React Native refers to the data or variables that determine a component's behavior and render dynamic content. It is an object that holds the current values of a component and can be updated by the component itself. The state is managed by the component and can be accessed and updated using the  useState  hook. const [name, setName] = useState("test user") In the example above, we are using the  useState  hook to create a state variable called  name  with an initial value of "test user". The hook returns an array with two elements - the current state value and a function to update the state value. In this case, we are destructuring the array to two v...

Exploring the Power of Custom Hooks in React/React Native Developers are constantly looking for ways to enhance the performance and functionality of their apps as the popularity of React Native continues to rise. Using custom hooks is a powerful tool that can help with this. Utilizing custom hooks, component logic can be converted into reusable functions. They keep your code organized and simple to maintain, allowing you to share logic across multiple components. By allowing you to only re-render the specific parts of your components that require updating, custom hooks can also improve performance. You must first write a function that begins with the word "use" in order to create a custom hook. After that, this function can manipulate state and props, call other hooks, and return a particular value or piece of functionality. You could, for instance, make a useFetch hook that gets data from an API and changes your component's state. When using custom hooks, one of the best...

Mastering the art of state management in React Native React Native is a powerful framework that allows developers to build high-performance mobile apps using JavaScript. One of the key concepts in React Native is state management, which refers to the process of managing and updating the data that drives your app. Proper state management is essential for building efficient and scalable apps, as it ensures that your app’s data is always up-to-date and consistent. However, managing state can also be one of the most challenging aspects of working with React Native. There are various ways to manage state in React Native, but the most popular and recommended approach is to use the setState() method, which allows you to update the state of a component and re-render it. Another popular approach is to use state management libraries like Redux or MobX, which provide a centralized store for your app’s data and actions. One of the best practices for managing state in React Native is to keep your s...

Leveraging React Native to  Create an Advanced Video Player In React Native, you can create a video player using the   react-native-video library. This library provides a simple API for playing videos in your app. To install the library, you can use the following command: npm install react-native- video or yarn add react-native-video Once the library is installed, you can use the  <Video>  component to play a video in your app: import Video from 'react-native-video' ; <Video source={{ uri: 'http://www.example.com/video.mp4' }} ref={(ref) => { this.player = ref }} onBuffer={this.onBuffer} onError={this.videoError} style={styles.backgroundVideo} /> The  source  prop takes an object with the video's URI, it can be a remote url or a local file. You can also customize the video player by passing props to the  <Video> component such as: controls  : to show or hide the player's controls resizeMode ...

Exploring useRef Hook in React Native Applications React's useRef hook lets you make a reference to a specific DOM element or component instance. Several scenarios can benefit from this, such as: Using this hook, you can focus an input field or measure a component's size by accessing the underlying DOM element, storing a value, such as a timer ID or an instance of a third-party library, that keep to remain constant across multiple renders of a component. Use useRef to make a reference to a text input and use it to focus the input when a button is clicked, as shown in the following example: A ref object with only one property, current, is returned by useRef. The initial value passed as an argument, if any, will be used to initialize this property, and its value can be changed by using ref.current = newValue. It is essential to keep in mind that useRef is distinct from useState, where component re-rendering is triggered by state updates. useRef only alters the current property an...

Improve image performance in react native using react native fast image? Image Caching: What Is It? When it comes to issues like images loading and re-rendering from remote destination, caching is an excellent solution. What image caching is all about is downloading an image to the app's cache directory or any other directory the app has access to and then loading it from local storage the next time the image loads. Picture caching can be done in a number of different ways in React Native. There is a fantastic component known as React Native FastImage that takes care of all of your image caching without you having to write any additional code if you are developing a basic React Native application.
