Error:
[@RNC/AsyncStorage]: NativeModule: AsyncStorage is null.
I got it when I try to run my app in expo with npm start
I got it last night, I fixed it and it worked till one hour ago, but now it’s here again.
I read other topics about the same error, but it doesn’t work for me.
my app.js code
import React from 'react';
import { Platform, StatusBar, StyleSheet, View, AsyncStorage} from 'react-native';
import { AppLoading, Asset, Font, Icon } from 'expo';
import AppNavigator from './navigation/AppNavigator';
import MainTabNavigator from './navigation/MainTabNavigator';
import * as firebase from 'firebase';
export default class App extends React.Component {
state = {
isLoadingComplete: false,
isAuthenticationReady: false,
isAuthenticated: false,
};
render() {
if (!this.state.isLoadingComplete && !this.props.skipLoadingScreen) {
return (
<AppLoading
startAsync={this._loadResourcesAsync}
onError={this._handleLoadingError}
onFinish={this._handleFinishLoading}
/>
);
} else {
return (
<View style={styles.container}>
{Platform.OS === 'ios' && <StatusBar barStyle="default" />}
<AppNavigator />
</View>
);
}
}
_loadResourcesAsync = async () => {
return Promise.all([
Asset.loadAsync([
require('./assets/images/robot-dev.png'),
require('./assets/images/robot-prod.png'),
]),
Font.loadAsync({
// This is the font that we are using for our tab bar
...Icon.Ionicons.font,
// We include SpaceMono because we use it in HomeScreen.js. Feel free
// to remove this if you are not using it in your app
'space-mono': require('./assets/fonts/SpaceMono-Regular.ttf'),
}),
]);
};

AsyncStorage
no longer in react-native
library:
import { Platform, StatusBar, StyleSheet, View, AsyncStorage} from 'react-native';
remove AsyncStorage
as a module and do npm install --save @react-native-community/async-storage
and then import into your file like so:
import AsyncStorage from '@react-native-community/async-storage';
