Make a Blur Background in React Native

Make a Blur Background in React Native

This is an Example to Make a Blur Background in React Native. To Make a Blur Background in React Native we will use BlurView component from @react-native-community/blur provided by react-native-community. This is very useful if you want to make a splash screen.

In this example, we will make a simple screen with a Switch to switch between simple and blurred screen and three buttons to switch different type of blur effects. So let’s get started.

Make BlurView using

Different Type of Blur Effects:

  1. xlight: Extra Light Blur Type
  2. light: Light Blur Type
  3. dark: Dark Blur Type
  4. extraDark: Extra Dark Blur Type(tvOS only)
  5. regular: Regular Blur Type (iOS 10+ and tvOS only)
  6. prominent: Prominent Blur Type (iOS 10+ and tvOS only)

Adjust Blur Intensity:
0-100 – Adjusts Blur Intensity
Note: The maximum blur amount on Android is 32, so higher values will be clamped to 32.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use BlurView we need to install @react-native-community/blur dependency.

To install this open the terminal and jump into your project using

Run the following command to install

This command will copy all the dependency into your node_module directory. –save is optional, it is just to update the @react-native-community/blur dependancy in your package.json file.

CocoaPods Installation

After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the library but need to install pods. So to install pods use

Now Open App.js in any code editor and replace the code with the following code.

App.js

To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).

IOS
