Getting Started

import 'package:flutter/foundation.dart' as foundation;

EmojiPicker(
    onEmojiSelected: (Category category, Emoji emoji) {
        // Do something when emoji is tapped (optional)
    },
    onBackspacePressed: () {
        // Do something when the user taps the backspace button (optional)
        // Set it to null to hide the Backspace-Button
    },
    textEditingController: textEditingController, // pass here the same [TextEditingController] that is connected to your input field, usually a [TextFormField]
    config: Config(
        height: 256,
        bgColor: const Color(0xFFF2F2F2),
        checkPlatformCompatibility: true,
        emojiViewConfig: EmojiViewConfig(
        // Issue: https://github.com/flutter/flutter/issues/28894
        emojiSizeMax: 28 *
        (foundation.defaultTargetPlatform == TargetPlatform.iOS
            ?  1.20
            :  1.0),
        ),
        viewOrderConfig: const ViewOrderConfig(
            top: EmojiPickerItem.categoryBar,
            middle: EmojiPickerItem.emojiView,
            bottom: EmojiPickerItem.searchBar,
        ),
        skinToneConfig: const SkinToneConfig(),
        categoryViewConfig: const CategoryViewConfig(),
        bottomActionBarConfig: const BottomActionBarConfig(),
        searchViewConfig: const SearchViewConfig(),
    ),
)

Examples

All examples can be found here

  1. Default (Some Emoji might not be displayed correctly e.g. Frowning Face 🚨 Will be fixed with 3.17)

  2. Custom Font (Display all emoji correctly in the style of the font, additional ~15mb e.g. with Google Fonts) - Might causes performance issues on iOS (see issue 205)

  3. WhatsApp like customization

*All screenshots from Android. iOS displays by default most emoji correctly.

Backspace-Button

Backspace button is enabled by default on the bottom action bar. If you prefer to have the backspace button inside the category tab bar, you can enable it inside the CategoryViewConfig and then extraTab to CategoryExtraTab.BACKSPACE. You can listen to the Backspace tap event by registering a callback inside onBackspacePressed: () { }. This will make it easier for your user to remove an added Emoji without showing the keyboard. Check out the example for more details about usage.

Custom view

The appearance is completely customizable by setting customWidget property. If properties in Config are not enough you can inherit from EmojiPickerView (recommended but not necessary) to make further adjustments.

class CustomView extends EmojiPickerView {
  CustomView(Config config, EmojiViewState state, VoidCallback showSearchBar,
      {super.key})
      : super(
          config,
          state,
          showSearchBar,
        );

  @override
  _CustomViewState createState() => _CustomViewState();
}

class _CustomViewState extends State<CustomView> {
  @override
  Widget build(BuildContext context) {
    // TODO: implement build
    // Access widget.config, widget.state and widget.showSearchBar
    return Container();
  }
}



EmojiPicker(
    onEmojiSelected: (category, emoji) {/* ...*/},
    config: Config(/* ...*/),
    customWidget: (config, state, showSearchView) => CustomView(
        config,
        state,
        showSearchView,
    ),
)

Each component can also be completely customized individually:

  • SearchViewConfig -> customSearchView

  • CategoryViewConfig -> customCategoryView

  • BottomActionBarConfig -> customBottomActionBar

Localization

The package currently supports following languages: en, de, es, fr, hi, it, ja, pt, ru, zh. In order to let the EmojiPicker choose the right language you need to pass the locale to the config:

Config(
    locale: const Locale("ja"),
)    

In case you want to support additional languages, you need to create a copy of a emoji set file (see /lib/locales), translate it (optional use /automation/create_emoji_set.sh to help you) and adjust the config for emojiSet:

EmojiPicker(
    config: Config(
         emojiSet: _getEmojiLocale,
    ),
)

List<CategoryEmoji> _getEmojiLocale(Locale locale) {
  switch (locale.languageCode) {
    case "ja":
      return emojiSetJapanese;
    case "de":
      return emojiSetGerman;
    default:
      return emojiSetEnglish;
  }
}

Example for using /automation/create_emoji_set.sh for generating translation in terminal:

  1. Fork the repository and open the directory from your terminal
  2. Run command below
cd automation && ./create_emoji_set.sh pt Portuguese

Feel free to create an issue if you think a specific language should be supported by default. We keep the languages limited for now to avoid the package size growing unnecesserily large.

In case you want to support only a single language you can just return the same EmojiSet for all locales.

List<CategoryEmoji> _getEmojiLocale(String locale) {
    return emojiSetEnglish;
}

Using a single EmojiSet will reduce the package size by about 2 MB. If you prefer to use the old EmojiSet (version 3 and below), you can return defaultEmojiSet.

Extended usage with EmojiPickerUtils

Find usage example here

// Get recently used emoji
final recentEmojis = await EmojiPickerUtils().getRecentEmojis();

// Search for related emoticons based on keywords
final filterEmojiEntities = await EmojiPickerUtils().searchEmoji("face", defaultEmojiSet);

// Add an emoji to recently used list or increase its counter
final newRecentEmojis = await EmojiPickerUtils().addEmojiToRecentlyUsed(key: key, emoji: emoji);
// Important: Needs same key instance of type GlobalKey<EmojiPickerState> here and for the EmojiPicker-Widget in order to work properly

// Highlight emojis with custom style spans
final textSpans = EmojiPickerUtils().setEmojiTextStyle('text', emojiStyle: style);

// Clear list of recent Emojis
EmojiPickerUtils().clearRecentEmojis(key: key);
