Rncviewpager was not found in the uimanager

by

Explanation:

The error message “rncviewpager was not found in the uimanager” typically occurs in React Native when the required package or module is not correctly linked or installed. This error is usually specific to the package named “react-native-viewpager” (rncviewpager).

Possible Causes:

  1. The package is not installed properly.
  2. The package needs to be linked manually to the project.
  3. The package is outdated and not compatible with your React Native version.

Solutions:

Here are a few steps to resolve this issue:

1. Check Installation:

Verify that the package is installed in your project by running the following command:

npm ls react-native-viewpager

If the package is not listed, install it using:

npm install react-native-viewpager --save

2. Link the Package:

Some packages require manual linking to work properly with React Native. To link the package, follow these steps:

  • If you are using React Native version 0.59 or below, run the command:
    • react-native link react-native-viewpager
  • If you are using React Native version 0.60 or above, the package should be auto-linked. If not, you can try to manually link it using:
    • npx react-native link react-native-viewpager

3. Verify React Native Version Compatibility:

Make sure the installed version of “react-native-viewpager” is compatible with your React Native version. Some packages may not work with specific React Native versions. Check the package’s documentation or GitHub repository for compatibility information.

Example Usage:

Assuming you have already installed the “react-native-viewpager” package, here’s an example of its usage:

{`
import React, { Component } from 'react';
import { View } from 'react-native';
import ViewPager from 'react-native-viewpager';

const images = [
  { uri: 'https://example.com/image1.jpg' },
  { uri: 'https://example.com/image2.jpg' },
  { uri: 'https://example.com/image3.jpg' },
];

class MyViewPager extends Component {
  render() {
    return (
       p1 !== p2 }).cloneWithPages(images)}
        renderPage={({ uri }) => }
      />
    );
  }
}

export default MyViewPager;
`}

In the above example, we import the “react-native-viewpager” package and use it to create a ViewPager component. The ViewPager displays a set of images using the provided data source and custom renderPage function.

Remember to replace the image URLs with your actual image sources in the above code. Additionally, handle any other necessary configurations, like styling, according to your requirements.

Hopefully, these steps and example will help you resolve the “rncviewpager was not found in the uimanager” error. If the issue persists, refer to the package’s documentation or seek help from the community.
