A Flutter plugin to check keyboard visibility.

keyboard_utils

A Flutter plugin to check keyboard visibility and height.

Install

Follow this guide

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.

Fechar os issues resolvidos.

@IsaiasSantana e wilfilho, parabéns pelo plugin. Simples e funciona bem.

@IsaiasSantana Seria interessante fechar (botão de "close") os issues que já foram resolvidos. Vi que a maioria dos 9 que estão abertos já estão resolvidos.

Listeners get deleted when you add new ones

There is a bug here:

  /// Subscribe to a keyboard event.
  /// [listener] object to listen the event.
  /// Returns a subscribing id that can be used to unsubscribe.
  int add({required KeyboardListener listener}) {
    final int length = _listenersKeyboardEvents.length;
    _listenersKeyboardEvents[length] = listener;
    return length;
  }

If you add one listener listener1 (length is 0, becomes 1):

{0: listener1}

Then add a second listener listener2 (length is 1, becomes 2):

{0: listener1, 1: listener2}

Then remove the one with id 0 (length is 2, becomes 1):

{1: listener2}

But now if you add a third listener listener3, since length is now 1, it will overwrite listener2, and you'd get:

{1: listener3}

The solution is creating an independent counter that never repeats:

static int _count = 0;

  /// Subscribe to a keyboard event.
  /// [listener] object to listen the event.
  /// Returns a subscribing id that can be used to unsubscribe.
  int add({required KeyboardListener listener}) {
    _listenersKeyboardEvents[_count] = listener;
    _count++;
    return _count;
  }

Saber qual tipo de teclado está aberto?

Seria possível saber qual o tipo de teclado que está aberto? Por exemplo, se o teclado aberto é o teclado numérico, ou o teclado qwerty comum? No builder poderia ter mais um parâmetro:

enum KeyboardType {numerical, qwerty, other}

class KeyboardOptions {
  KeyboardOptions({required this.isKeyboardOpen, required this.keyboardHeight});

  final bool isKeyboardOpen;
  final double keyboardHeight;
  final KeyboardType keyboardType;
...

the height is not corrent

in some new oppo vivo mate20 phone, can get the height ,but the height value is not correct,or high or low

Keyboard height is wrong on Android

Hi there!
The keyboard height I get from your library seems to be wrong. The value is 30 logical pixels too low I think. For visualization I created a Container that sits behind the keyboard thank to an OffStage widget and resizeToAvoidBottomInset: false,

Here a minimum reproducible example that is based on your example:

import 'dart:async';

import 'package:flutter/material.dart';

import 'package:keyboard_utils/keyboard_utils.dart';

This example only works an my Android 10 device (Xiaomi Mi A2 Lite) if I use _bloc.keyboardUtils.keyboardHeight + 30 instead of the normal height.
I afraid that this value is different for each device. Is there a way to fix this? @IsaiasSantana @wilfilho

I used it as regular. the event _onKeyboardListener is not called when the keyboard is closing on my Galaxy S10e and not called at all on my emulator.

Thank you!

Project does not run with new Flutter 2.10.0

After I updated the Flutter from v2.8.1 to v.2.10.0 my app does not run on both macOS and Windows (proven by other colleagues). Running commands like flutter clean and flutter doctor is not solving the issue - the app is still not able to run.

I tried to manually fix this line mentioned in the warning but it seemed not helped.
