What is the method of identifying whether the keyboard is opened or closed in React Native?

edit

In React Native, the keyboard can be detected as open or closed using the Keyboard API from the react-native core module.

One way to identify whether the keyboard is open or closed is by adding event listeners using the Keyboard API in the componentDidMount() and componentWillUnmount() lifecycle methods.

Example code:

import {Keyboard} from 'react-native';

class Example extends React.Component {
  constructor(props) {
    super(props);
    this.keyboardDidShowListener = Keyboard.addListener(
      'keyboardDidShow',
      this._keyboardDidShow,
    );
    this.keyboardDidHideListener = Keyboard.addListener(
      'keyboardDidHide',
      this._keyboardDidHide,
    );
  }

  componentWillUnmount() {
    this.keyboardDidShowListener.remove();
    this.keyboardDidHideListener.remove();
  }

  _keyboardDidShow() {
    console.log('Keyboard is open');
  }

  _keyboardDidHide() {
    console.log('Keyboard is closed');
  }

  render() {
    return <View>{/* Your component code */}</View>;
  }
}

In this example, the _keyboardDidShow() and _keyboardDidHide() functions are called when the keyboard is opened or closed respectively.
