Seamless Transition Between Keyboard and Emoji Picker in Flutter: A Step-by-Step Guide

As a developer, improving your skills is an ongoing process that requires dedication and practice. One of the best ways to enhance your skills is by implementing complex features in your projects. In this article, we will focus on creating a seamless transition between the keyboard and the emoji picker in a Flutter chat UI, similar to apps like Telegram and WhatsApp.

To improve your skills, I'm trying to implement a chat UI that mimics the behavior of apps like Telegram and WhatsApp. In those apps, the transition between the keyboard and the emoji picker is seamless. However, achieving this in Flutter can be challenging, especially for developers who are new to the platform.

The main issue is that the keyboard and the emoji picker are two separate widgets that need to be managed simultaneously. When the user clicks on the emoji button, the keyboard should hide, and the emoji picker should appear. Conversely, when the user clicks on the text input field, the emoji picker should hide, and the keyboard should appear.

To achieve a seamless transition between the keyboard and the emoji picker, we need to meet the following requirements:

  • The keyboard and the emoji picker should be two separate widgets.
  • The keyboard should hide when the emoji picker appears, and vice versa.
  • The transition between the keyboard and the emoji picker should be smooth and seamless.

To design the UI, we will use the following widgets:

  • TextField: This widget will be used to display the text input field.
  • EmojiPicker: This widget will be used to display the emoji picker.
  • Keyboard: This widget will be used to display the keyboard.

We will use the Stack widget to stack the TextField, EmojiPicker, and Keyboard widgets on top of each other.

Stack(
  children: [
    TextField(
      // ...
    ),
    EmojiPicker(
      // ...
    ),
    Keyboard(
      // ...
    ),
  ],
)

To manage the keyboard and the emoji picker, we will use the following approach:

  • When the user clicks on the emoji button, we will hide the keyboard and show the emoji picker.
  • When the user clicks on the text input field, we will hide the emoji picker and show the keyboard.

We will use the Visibility widget to hide and show the keyboard and the emoji picker.

Visibility(
  visible: _isEmojiPickerVisible,
  child: EmojiPicker(
    // ...
  ),
)

Visibility(
visible: !_isEmojiPickerVisible,
child: Keyboard(
// ...
),
)

To implement the logic, we will use the following approach:

  • We will create a boolean variable _isEmojiPickerVisible to track whether the emoji picker is visible or not.
  • When the user clicks on the emoji button, we will set _isEmojiPickerVisible to true.
  • When the user clicks on the text input field, we will set _isEmojiPickerVisible to false.

We will use the setState method to update the _isEmojiPickerVisible variable.

void _toggleEmojiPicker() {
  setState(() {
    _isEmojiPickerVisible = !_isEmojiPickerVisible;
  });
}

To put it all together, we will create a new Flutter project and add the following code:

import 'package:flutter/material.dart';

void main() {
runApp(MyApp());
}


class MyApp extends StatelessWidget 
@override
Widget build(BuildContext context) {
return MaterialApp(
home ChatUI(),
);

}


class ChatUI extends StatefulWidget {
@override
_ChatUIState createState() => _ChatUIState();
}


class _ChatUIState extends State<ChatUI> {
bool _isEmojiPickerVisible = false;


void _toggleEmojiPicker() {
setState(() {
_isEmojiPickerVisible = !_isEmojiPickerVisible;
});
}


@override
Widget build(BuildContext context) 
return Scaffold(
appBar AppBar(
title: Text('Chat UI'),
),
body: Stack(
children: [
TextField(
// ...
),
Visibility(
visible: _isEmojiPickerVisible,
child: EmojiPicker(
// ...
),
),
Visibility(
visible: !_isEmojiPickerVisible,
child: Keyboard(
// ...
),
),
],
),
);

}

In this article, we have learned how to create a seamless transition between the keyboard and the emoji picker in a Flutter chat UI. We have used the Stack widget to stack the TextField, EmojiPicker, and Keyboard widgets on top of each other. We have also used the Visibility widget to hide and show the keyboard and the emoji picker. Finally, we have implemented the logic to toggle the visibility of the emoji picker and the keyboard.

By following this guide, you should be able to create a seamless transition between the keyboard and the emoji picker in your own Flutter chat UI.

There are several ways to improve this code:

  • Add animations to the transition between the keyboard and the emoji picker.
  • Add a button to toggle the visibility of the emoji picker.
  • Add a feature to search for emojis in the emoji picker.
  • Add a feature to add custom emojis to the emoji picker.

These are just a few ideas, and there are many other ways to improve this code. The key is to experiment and try new things to see what works best for your project.

Creating a seamless transition between the keyboard and the emoji picker in a Flutter chat UI requires careful planning and implementation. By following this guide, you should be able to create a seamless transition between the keyboard and the emoji picker in your own Flutter chat UI. Remember to experiment and try new things to see what works best for your project. Happy coding!
Q&A: Seamless Transition Between Keyboard and Emoji Picker in Flutter

In our previous article, we discussed how to create a seamless transition between the keyboard and the emoji picker in a Flutter chat UI. However, we know that there are many questions that still need to be answered. In this article, we will address some of the most frequently asked questions about creating a seamless transition between the keyboard and the emoji picker in Flutter.

A: The best way to handle the transition between the keyboard and the emoji picker is to use the Visibility widget to hide and show the keyboard and the emoji picker. This will allow you to control the visibility of the keyboard and the emoji picker based on the user's input.

A: To add animations to the transition between the keyboard and the emoji picker, you can use the AnimatedBuilder widget. This widget will allow you to animate the visibility of the keyboard and the emoji picker based on the user's input.

A: To add a button to toggle the visibility of the emoji picker, you can use the IconButton widget. This widget will allow you to add a button to the UI that will toggle the visibility of the emoji picker.

A: To add a feature to search for emojis in the emoji picker, you can use the TextField widget. This widget will allow you to add a search bar to the emoji picker that will allow users to search for emojis.

A: To add a feature to add custom emojis to the emoji picker, you can use the TextField widget. This widget will allow you to add a text field to the emoji picker that will allow users to enter custom emojis.

A: Some common issues that you may encounter when creating a seamless transition between the keyboard and the emoji picker include:

  • The keyboard and the emoji picker not hiding and showing correctly.
  • The animations not working correctly.
