2. Dart From padawan to jedi in one week
4. _DOUGLASGIMLI
11. Why Dart & Flutter?
13. • Dart as the main language • One language, multiple platforms • Open source • Maintained by Google • Simple and scalable • No bridge context switches • Optimised Garbage collector • Unified layout • Dart Code only Dart & Flutter
14. Developing the application
19. • Widgets, widgets everywhere… ◦ AppBar ◦ Container ◦ Padding ◦ Sizing ◦ Column and Row ◦ Image and Text ◦ Listview • Stateless and Stateful ◦ Stateless receive and consume arguments from parent Widgets ◦ Stateful know how to create and manipulate states UI
21. • Service layer ◦ Async ◦ Future Aka Promises • Folder structure ◦ Lib folder ◦ Same as my web flow • Persist data ◦ User preferences ◦ SQLite • Native tests Data management
22. Not only rainbows and butterflies...
23. Crash.. Crash everywhere..
24. • Errors that crashed the debugger ◦ A lot of cleans… • Version 0.2.. • Careful with the Hadouken code ◦ Widgets everywhere… • Complex state management ◦ No observables ◦ Flux in action Problems in paradise
25. Final version
26. • It was easy to have an prototype in hands ◦ But.. to immature yet • Environment missing features ◦ Poor iOS style widgets • Community Small ◦ Compared to React Native • Has Dart as the primary language ◦ Which is support by Google • Not there yet, but for sure it’s on the right path! Final thoughts
