Invariant Violation: TurboModuleRegistry.getEnforcing(...): 'NativeReanimated' could not be found

Question

so this is the first time I used Reanimated 2 and unfortunately my App get crashed with the above message. Unable to view my app screen.

Invariant Violation: TurboModuleRegistry.getEnforcing(...): 'NativeReanimated' could not be found. Verify that a module by this name is registered in the native binary.

I'm using reanimated here

import React from 'react'
import Item from '../../Common/Item'
import {View,Text,FlatList,StyleSheet , TouchableOpacity} from 'react-native'

import Animated, {useAnimatedStyle} from 'react-native-reanimated';
import {bin,mix,useTiming} from 'react-native-redash' 


const {interpolate,not}=Animated
const SectorItem=({sector,clients,index,opened,toggleSector})=> {
        const {name}=sector
        const ITEM_HEIGHT = 100
        const transition = useTiming(opened)
        const style = useAnimatedStyle(()=>({
          height: mix(transition,0,clients.length * ITEM_HEIGHT)
        }))
      
        //here we wll also have the clients of each sector 
        return <Item xStyle={styles.item}>
                <View>
                    <Text>{name}</Text>
                    <TouchableOpacity onPress={e=>toggleSector(index)}>
                      <Text>open</Text>
                    </TouchableOpacity>
                </View>
                <Animated.View style={style}>
                    <FlatList 
                       data   = {clients}
                       style  = {{...styles.Clientlist,display:opened?'flex':'none'}}
                       contentContainerStyle = {props =>(styles.flatList)}
                       showsVerticalScrollIndicator={false}
                       renderItem   = {({ item }) =><Item xStyle={{marginBottom:8}}> 
                         <TouchableOpacity>
                           {/* redirect to client  */}
                              <Text>{item.name} </Text>
                         </TouchableOpacity>
                       </Item> }
                       keyExtractor = {(item, index) => index.toString()}
                    />
                </Animated.View>
        </Item>
   
}

export default SectorItem
var styles = StyleSheet.create({
    list:{
        borderColor:'#fff',
        padding:16,
    },
    Clientlist:{
        borderColor:'#fff',
        padding:16,
    },
    flatList:{ 
        alignItems: 'center',
         justifyContent: 'center', 
         height:200,
         flex:1
    },
    item:{
        marginBottom:8
    }
  });

Answer 1

reanimated package is not auto-linked in android, please follow the steps mentioned on the official documentation.

You need to make changes in android/app/build.gradle

project.ext.react = [
 enableHermes: true,  // clean and rebuild if changing
]

add following in babel.config.js

plugins: ['react-native-reanimated/plugin']

add following in MainApplication.java

    @Override
    protected JSIModulePackage getJSIModulePackage() {
      return new ReanimatedJSIModulePackage(); // <- add
    }

Answer 2

I've downgrande "react-native-reanimated": "2.0.0" to "react-native-reanimated": "1.13.0",
