Flutter

Flutter est un kit de développement logiciel (SDK) d'interface utilisateur open-source créé par Google en 2011. Il est utilisé pour développer des applications pour Android, iOS, Linux, Mac, Windows, Google Fuchsia et le web à partir d'une seule base de code (en Dart).

• La langage Dart
• Le Moteur Flutter (écrit en C++), s'interface avec les SDK spécifiques aux plateformes
• La Bibliothèque Foundation (API pour communiquer avec le moteur)
• Les Widgets spécifiques à la conception (Material Design-Androïd | Cupertino-Ios)

# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev
 
# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.

# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
