CinJUG: "How Should Java Developers Build Front-Ends for Web, Mobile, and Desktop Today?"
Users access applications on PCs and mobile devices today. There are two obvious ways to build front-ends for these devices: Web applications and native applications. Cross-platform UI toolkits combine advantages from both approaches. Examples are Facebook’s React Native, Google’s Flutter, Microsoft’s Xamarin, and JavaFX. I will look at these toolkits from the perspective of a Java developer. My talk will suggest which toolkits to use, what their sweet spots are, and when you should avoid them.
In 2019, I developed a mobile app prototype with Flutter and a progressive web application. I then decided to use Flutter for native mobile apps in my current project. I’ll demo these apps and select development tools in the talk. Finally, I will highlight typical issues with Flutter and how to solve them.
Here are the slides as PDF. They are 7 MB:
You can also get the slides in their original Keynote format. “Keynote” is Apple’s presentation application. Why would you do that? I animated the slides so they are more pleasant to watch. Or maybe you want to peek under the hood to see how I achieved specific effects. These slides include two videos and are 40 MB in size!
The slides use the following images:

My talk mentions a Flutter prototype I built in the summer of 2019. Here it is:
My talks also mentions a Progressive Web App prototype I built at the end of 2019. Here you go:
Flutter & Dart
Here are the instructions, straight from the Flutter website:
Here’s a selection of Flutter tutorials and courses:
- Google has a number of free tutorials for Flutter.
- freeCodeCamp has at least two free Flutter courses:
- Code with Andreas has two paid courses:
- Finally, academind has a 41-hour Flutter course. I used the 2019 version to learn Flutter and can highly recommend it!
