How to show a checkbox in reactnative?

Checkboxes is a common component that we often use on the UI. We do have some cool ways of showing checkboxes in reactnative.

The core react-native package does not have checkbox support and you need to install a package to work with it.

Following package has to be installed to display checkbox −

npm install --save-dev react-native-paper

The basic checkbox component is as follows −

<Checkbox status={checkboxstatus} onPress={onCheckboxCheckedfunc} />

Let us now see some important properties on checkbox −

Here is a simple checkbox display −

The useState is used to set the checked , unchecked status for the checkbox as shown below −

const [checked, setChecked] = React.useState(false);

The state is maintained inside checked variable and setChecked method is used to update it.

The checked status will be updated when user checks/unchecks the checkbox as shown below −

onPress={() => {
   setChecked(!checked);
}}

The complete code is as follows −

Example

import * as React from 'react';
import { StyleSheet, Text, SafeAreaView } from 'react-native';
import { Checkbox } from 'react-native-paper';
const MyComponent = () => {
   const [checked, setChecked] = React.useState(false);
   return (
      <SafeAreaView style={styles.container}>
         <Checkbox
            status={checked ? 'checked' : 'unchecked'}
            onPress={() => {
               setChecked(!checked);
            }}
            color={'green'}
            uncheckColor={'red'}
         />
      <Text>Checkbox</Text>
      </SafeAreaView>
   );
};
const styles = StyleSheet.create({
   container: {
      flex: 1,
      justifyContent: 'center',
      alignItems: 'center'
   },
});
export default MyComponent;
