Textarea React Native

Getting Started with Textarea Component in React Native

Textarea is an essential component used in a variety of applications for taking input from users. The Textarea component in React Native is similar to the HTML textarea element, and it provides a multi-line input field for users to input text. In this article, we will guide you through the process of incorporating the Textarea component into your React Native application.

Step 1: Installing Dependencies

Before we can use the Textarea component, we need to install the required dependencies for our React Native application. Open the terminal and run the following command:

npm install react-native-textarea --save

Step 2: Importing Component

After installing the required dependency, we need to import the component in our React Native application. Add the following import statement at the top of your component file:

import Textarea from 'react-native-textarea';

Step 3: Using Component

Now that we have installed the necessary dependencies and imported the Textarea component, we can use it in our application. The following code demonstrates how to use the Textarea component:

In this example, we have set the height of the Textarea component to 200 and added an `onChangeText` event listener that calls a function `onChangeText` whenever the user types anything in the component. We have also set the default value of the Textarea to the state variable, `text`.


In this article, we have discussed how to get started with the Textarea component in React Native. We have covered the installation of the required dependencies, importing of the component, and using it in a React Native application. You can use this component to create input fields that allow users to enter multi-line text input in your React Native applications.

Customizing Textarea Component in React Native

If you want to customize the look and feel of the default Textarea component in React Native, you can do so using various styling methods. Here are some ways to customize the Textarea component:

1. Styling the component

You can use the style prop on the Textarea component to add custom styles to it. For example:

This will add a light gray background color and a border-radius of 10px to the Textarea component.

2. Using custom fonts

You can use custom fonts in your Textarea component by importing them in your project and then referencing them in your style prop. For example:

import { StyleSheet } from 'react-native';
import { fontFamily } from '../styles/fonts';

const styles = StyleSheet.create({
  textarea: {
    fontFamily: fontFamily.One,
    fontSize: 18,
    fontWeight: '400',
    color: '#333',

export default function CustomTextarea() {
  return (

In this example, we’re using a custom font by importing it from a separate file and referencing it in the style prop on the Textarea component.

3. Adding placeholder text

You can add placeholder text to your Textarea component using the placeholder prop. For example:

This will add the text “Enter your message here” as a placeholder inside the Textarea component.

By using these and other styling techniques in React Native, you can easily customize the Textarea component to match your app’s design and branding.

Building a Multi-line Text Input with Textarea Component in React Native

If you’re looking to build a multi-line text input in your React Native app, the Textarea component is what you need. The Textarea component allows users to input text that spans multiple lines, just like a traditional textarea in HTML.

To use the Textarea component in your React Native app, you’ll need to import it from the react-native package:

import { Textarea } from ‘react-native’;

Once you’ve imported the Textarea component, you can use it in your app’s render method like this:

render() {
return (


In this example, the Textarea component is rendered with an event handler for onChangeText and a value prop that is set to the component’s state.

You can also customize the appearance and behavior of the Textarea component by using props like placeholder, autoFocus, and maxLength.



With these props, you can set a placeholder text, control the autoFocus behavior, set a maximum length, and customize the style of the text area component.

Overall, the Textarea component in React Native is a powerful tool for building multi-line text inputs in your app. With its flexibility and customizable props, you can create a text input that fits your app’s needs and provides a great user experience.

Handling User Input in React Native Textarea Component

The React Native Textarea component is a convenient way for users to input large amounts of text on a mobile device. However, it’s important to properly handle user input in this component to ensure a smooth user experience.

One way to handle user input is to use the onChange prop provided by the Textarea component. This prop allows you to pass a function that will be called whenever the user types in the Textarea. You can use this function to update the state with the user’s input.

Another way to handle user input is to use the onSubmitEditing prop. This prop allows you to pass a function that will be called when the user submits their input, such as by pressing the return key. You can use this function to process the user’s input or to move focus to the next input field.

Both of these props can be used together to create a seamless input experience for the user. By properly handling user input in the React Native Textarea component, you can improve the functionality and usability of your mobile app.

Styling Textarea Component with CSS in React Native

Textarea component is widely used in forms while developing an app, styles are very important part of user interface to make it look appealing to end user.
In React Native, You can use CSS style along with inline CSS properties to style textarea. Use the following CSS properties to style textarea component,

  • color – To set the color of the text
  • fontSize – To set the size of the text
  • backgroundColor – To set the background color of the textarea
  • borderColor – To set the color of the border around the textarea
  • borderRadius – To set the rounded corners of the textarea
  • padding – To set the padding inside the textarea

If you want to apply these CSS styles as a global style to all textareas in your project you can use StyleSheet API to create the style class and import it on all the page where you need textarea.

Best Practices for Using Textarea Component in React Native

When it comes to creating forms and allowing users to enter large amounts of text, the Textarea component in React Native can be incredibly useful. However, there are a few best practices that you should keep in mind to ensure that your implementation is as effective and user-friendly as possible.

First, it’s important to consider the size and placement of your Textarea component. While it’s tempting to create a large, multi-line Textarea that spans the entire screen, this can be overwhelming for users and may even make it difficult to read what they’ve typed. Instead, consider breaking your form up into smaller sections and using appropriately sized Textareas for each one.

Next, it can be helpful to provide users with additional context or guidance on what they should be entering into the Textarea. This can be achieved through the use of labels, placeholders, or even helper text that appears below the component as users are typing.

Another best practice is to ensure that the user’s typed content is automatically saved or is not lost if they navigate away from the form or close the app. This can be achieved by implementing auto-save functionality or by prompting users to confirm if they want to leave the form before their data is saved.

Finally, it’s important to ensure that your Textarea component is accessible to all users, including those with disabilities. This can be achieved through the use of appropriate labels, assistive technologies, and by testing your implementation with a screen reader.

By following these best practices, you can create a Textarea component in React Native that is both effective and user-friendly, and that provides users with an easy and intuitive way to enter large amounts of text.

Advanced Techniques for Building Rich Text Editors in React Native with Textarea Component

When it comes to building a rich text editor in React Native, the Textarea component can be your best friend. The component provides a simple way to input and output text, but with some advanced techniques, you can turn it into a powerful tool for creating and formatting text.

One important technique is using the selection property of the Textarea component. This allows you to highlight and manipulate selected text, such as making it bold or italicized. You can also use the selection property to insert text at specific points in the editor, or to replace selected text with new content.

Another technique is utilizing the onChangeText property to detect when the text in the editor has changed. With this method, you can set up custom functions to parse and format the text as it’s being entered, allowing for real-time previewing of the final output.

Finally, you can take advantage of the onFocus and onBlur properties to provide additional functionality when the editor gains or loses focus. For example, you can use these properties to show or hide formatting options or to display a character count for the text in the editor.

By utilizing these advanced techniques, you can turn the Textarea component in React Native into a powerful tool for building rich text editors. With the ability to manipulate selected text, format text in real-time, and provide additional functionality based on focus, the possibilities are endless.
