Free certificationFlutter Certification
A free, verifiable certificate of completion for Coddy's Flutter course. You earn it by building real Flutter apps in Dart, run by the Flutter web engine on a phone screen beside the editor: widgets, layout, setState, lists and screens, Provider and Riverpod, and data from the network with FutureBuilder. There is nothing to install. Each of the seven sections issues its own certificate, shareable on LinkedIn or your CV.
Inside the journey
Each section below issues its own certificate when completed. Browse the full journey to see every lesson and challenge.
01
Your First AppYour first Flutter apps: what Flutter is, the widget tree, text and its style, colored boxes, padding, rows and columns, icons and images, and the Dart you need along the way. Ends with a business card app.
02
Making It InteractiveApps that answer back: buttons, functions and the Console, StatefulWidget and setState, const and final, decisions with if and booleans, text fields, switches, checkboxes and sliders, and the Dart behind them. Ends with a tip calculator app.
03
Lists and ScreensApps with more than one screen: scrolling lists and list tiles, cards and grids, your own Dart classes for your data, moving between screens and passing data along, tabs, a drawer and swipe to delete. Ends with a recipe book app.
04
Layout That FitsScreens that fit any phone: sharing a row with Expanded, Flexible and Spacer, reading and fixing the overflow error, Wrap, Stack and Positioned, SafeArea, maximum widths, screen sizes and breakpoints, enums and switch, app themes and dark mode. Ends with a music player screen.
