Want to learn to build beautiful Flutter apps that users can navigate through easily, fetching data along the way? Then this two-day hands-on Flutter and Dart workshop is for you!
Mobile development is a difficult task these days. Not only do we need to write beautiful, high-performance apps that work on low-powered devices with intermittent connectivity, we need to write our apps twice! Once for iOS, and again for Android.
Flutter is a new mobile UI framework from Google that allows us to develop high quality apps for both iOS and Android using a single code base. It features a lightning-fast development experience, fluid animations, and native performance. If you're looking to speed up your mobile development, ship to both platforms, and have fun in the process, this course is for you!
Begin with a crash-course in the easy-to-learn, easy-to-scale Dart language, before moving on to use it to build your own working app.
Learn how to:
- Understand basic Dart syntax and fundamentals
- Quickly create apps which look consistent across iOS and Android platforms
- Create standard layouts with Flutter and populate them with data from the cloud
- Create lists of items for a mobile app
- Seamlessly convert difficult designs into Flutter widgets
- Understand how to change what's displayed on screen in response to user interactions
- Run into your own challenges and solve them
- Test your Flutter apps
