Party Flutter

Mobile party game implemented in Flutter framework. Its been heavily inspired by the Heads Up! game:

  • Get a group of friends (at least 3 players)
  • Start the app
  • The youngest player takes the phone
  • Pick one of the available categories/topics (eg. Animals, TV series, Sport)
  • Place the phone at your forehead, so that other players can see the screen
  • Guess the word displayed at the screen - your friends are here to help you!


The existing production version has been implemented in hybrid technologies and you can check it out at:

Just a note - it's only available in Polish language. The current repository is an approach to rewrite it fully in Flutter.



Adding new language

  1. Add language code to getCodes method in language.dart
  2. Download language flag from here and put it in assets/images/flags/
  3. Make a copy of file intl_messages.arb and translate the sentences (not the ones prefixed by @). See theintl_messages_pl.arb for reference
  4. When the translations are ready - run the Generate translations section
  5. The UI is translated! The only remaining thing is to add own set of categories and questions in assets/data/. Each category consists of:
  • id - unique identifier of category (just make sure it's unique across the file)
  • image - image name for the category which is stored in assets/images/categories/. Feel free to add your own images - should be non-transparent, 400x400, PNG files. Can be downloaded from or
  • name - category name in yours language
  • questions - list of available questions - min. 50 per category, but more is better :)
  1. Done, new language added - PRs are more than welcome

Generate translations

  • flutter pub pub run intl_translation:extract_to_arb --output-dir=lib/l10n lib/localizations.dart
  • flutter pub pub run intl_translation:generate_from_arb --output-dir=lib/l10n --no-use-deferred-loading lib/localizations.dart lib/l10n/intl_*.arb



  • Improve the UI
  • Organize the code
  • More animations
  • A lot more
