How to use

Add the imports:

import 'package:keyboard_utils/keyboard_utils.dart';
import 'package:keyboard_utils/keyboard_listener.dart';

Create the KeyboardUtils:

KeyboardUtils  _keyboardUtils = KeyboardUtils();

Attach the listener to KeyboardUtils:

final int _idKeyboardListener = _keyboardUtils.add(
        listener: KeyboardListener(willHideKeyboard: () {
      // Your code here
    }, willShowKeyboard: (double keyboardHeight) {
      // Your code here
    }));

Remember call dispose:

_keyboardUtils.unsubscribeListener(subscribingId: _idKeyboardListener);
    if (_keyboardUtils.canCallDispose()) {
      _keyboardUtils.dispose();
    }

Instead, you can also use KeyboardAware Widget:

 import 'package:keyboard_utils/widgets.dart';
 
 ....
 
 Widget buildSampleUsingKeyboardAwareWidget() {
    return Center(
      child: Column(
        children: <Widget>[
          TextField(),
          TextField(
            keyboardType: TextInputType.number,
          ),
          TextField(),
          SizedBox(
            height: 30,
          ),
          KeyboardAware(
            builder: (context, keyboardConfig) {
              return Text('is keyboard open: ${keyboardConfig.isKeyboardOpen}\n'
                  'Height: ${keyboardConfig.keyboardHeight}');
            },
          ),
        ],
      ),
    );
  }
  
  ....

To share KeyboardConfig in your widget tree, use the KeyboardConfigInheritedWidget widget.
