Flutter 与 Dart
一套代码，同时覆盖 iOS 和 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.
