What is Leitmotif? #
A collection of widgets and screens for Flutter implementing the Leitmotif Design Language. It complements the default Material Widgets shipped with Flutter. Whose Widgets include custom implementation of Snackbars, AppBars and a settings panel. Utility Screens (e.g. required to verify the user's age and to show the application's licenses) are also included.

'Leitmotif' is derived from the German noun 'Leitmotiv' which describes a dominant and recurring theme in music and literature.

Leitmotif is based on the LitUIKit project, which has been discontinued.

Localizations #
Leitmotif's widgets are currently localized in English and German.
To use Leitmotif's default localizations in your Flutter app make sure to utilize the LeitmotifLocalizationsDelegate on yourMaterialApp.
Some widgets also require the GlobalMaterialLocalizations.delegate, GlobalWidgetsLocalizations.delegate and GlobalCupertinoLocalizations.delegate.
return MaterialApp(
title: 'Leitmotif',
localizationsDelegates: const [
LeitmotifLocalizations.delegate,
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
],
supportedLocales: const [
Locale(LeitmotifLocalizationsEn.languageCode, ''),
Locale(LeitmotifLocalizationsDe.languageCode, ''),
],
home: ExampleHomeScreen(),
);

Icons #
Leitmotif does utilize its own icons (LitIcons). They are stored inside a ttf file and are implemented as Dart IconData objects.
