Débutant Quartier du code

Flutter et Dart

Une seule base de code pour iOS et Android.

Flutter is Google's toolkit for building apps from one codebase, and Dart is the language you write them in. This track starts from zero: Dart's essentials with null safety, then widgets, layouts, themes and state, then a real app that loads JSON from the internet and moves between screens.

The examples come from a small social app called Nova: a points badge, a post card, a like button and a leaderboard. Every Dart program shows exactly what it prints, so you always know what to expect.
