Invariant violation: requirenativecomponent: “rngesturehandlerrootview” was not found in the uimanager.

Invariant Violation – requireNativeComponent

This error occurs when using React Native and the component “rngesturehandlerrootview” is not found in the UIManager. The UIManager is responsible for managing the native components in React Native.

The “rngesturehandlerrootview” component is a built-in component that enables gesture handling and touch interactions in React Native applications. It is usually required by other gesture-related components such as FlatList, ScrollView, etc.

Possible Causes:

1. Missing or outdated dependencies: Check if you have the required dependencies installed correctly in your project.
2. Incorrect imports: Make sure you are importing the correct components and modules.
3. Version incompatibility: Ensure that all related libraries and components are compatible with each other.
4. Build issues: If you’re working on an ejected React Native project, check if the necessary configurations are correctly set up.

Solution:

Here are a few steps to resolve this issue:

1. Verify dependencies: Check your project’s package.json file and ensure that you have the required dependencies installed (e.g., react-native-gesture-handler).
2. Reinstall node modules: Delete the node_modules folder and reinstall all dependencies using npm install or yarn install.
3. Link the library: Make sure to link the necessary libraries and modules to your project using react-native link. Specifically, the react-native-gesture-handler library needs to be linked.
4. Clear build cache: If you’re using Android, try running the following command: react-native start --reset-cache and then rebuild your project.
5. Check imports: Double-check if you are importing the correct components and modules in your code.

Example:

An example of using the “rngesturehandlerrootview” component can be found below:

      
        import React from 'react';
        import { View } from 'react-native';
        import { RNGestureHandlerRootView } from 'react-native-gesture-handler';

        const App = () => {
          return (
            <RNGestureHandlerRootView style={{ flex: 1 }}>
              <View style={{ flex: 1 }}>
                {/* Your application content */}
              </View>
            </RNGestureHandlerRootView>
          );
        };

        export default App;
      
    

Please note that the above example assumes that you have the “react-native-gesture-handler” library installed and properly linked in your project.
