Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
import React, { useState } from 'react';
import { StyleSheet, Text, View, Button } from 'react-native';
import CheckBox from '@react-native-community/checkbox';
export default function Checkbox() {
const [state, setState] = useState({ react: false });
return (
<View>
<CheckBox
value={state.react}
onValueChange={value =>
setState({
...state,
react: value,
})
}
/>
<Text>React js</Text>
</View>
);
}
