This series of posts covers mobile app development with Google's UI toolkit, Flutter. Flutter apps are written in Dart and can be compiled into Android, iOS, and web apps all using a single codebase.
You will be asked to follow along with the programs below. Just click on the links and a code playback will load (you might want to open each one in a new tab). Then click on the comments on the left hand side of the screen or hit the play button to drive the development of the code. You can download the code at any point or copy/paste it. There are some controls in the top right hand side of the screen to make the text bigger or to switch to blog mode (which is good for small screens).
This playback covers installing the tools needed to run Dart programs and to build Flutter apps.
These playbacks cover basic data types in Dart including some data structures.
These playbacks covers ifs, loops, and functions.
Asynchronous programming is critical in UI focused programs like Flutter apps. This playback begins to cover Futures and await/async.
This playback covers classes in Dart. There are some interesting features of Dart classes like named constructors and initializers.
You can find all of these code playbacks in my free 'book', Mobile App Development with Dart and Flutter. I am always looking for feedback so please feel free to comment here or to send me a message. You can follow me on twitter @markm208.
