A strong framework for creating cross-platform mobile applications is React Native. The popover view is a popular user interface pattern that lets you show more options or information in a floating window. We'll go over how to create a popover view in React Native in this blog post.
Make sure Node.js and npm (Node Package Manager) are installed on your computer before we start. To start a new React Native project, make sure you have the React Native CLI installed as well.
- npm install -g react-native-cli
Create a new React Native project
To get started, let's make a brand-new React Native project. Launch the following command in an open terminal window:
- npx react-native init PopoverExample
PopoverExample, a new React Native project, will be created as a result.
The library that offers the popover capability must then be installed. We'll be using the react-native-popover-view library in this example.
We import all required dependencies, including Popover from react-native-popover-view, into this component. Additionally, we control the popover's visibility using the useState hook.
The popover is displayed when the showPopover function sets the isVisible state to true. In contrast, when the hidePopover function is called, the popover is hidden.
Implementing the Popover component
Using the PopoverComponent in our main application file (App.js) is the next step.
We import PopoverComponent into this file, then render it inside of a View component. We additionally center the popover on the screen by applying a few simple styles.
Running the application
Enter the following command into your terminal to observe the popover view in action:
- npx react-native run-android
- npx react-native run-ios
By doing this, you may open your app in an iOS or Android emulator and start the development server.
We've shown in this blog article how to use the react-native-popover-view library to construct a popover view in a React Native application. The popover's look and behavior can be further altered to meet your unique needs. This sample gives you a basic idea of how to incorporate popovers into your React Native projects.
