Flokk – How we built a Desktop App Using Flutter

Earlier this year Google and Ubuntu approached us with an open brief, to try and create a full-scale desktop application for Linux, macOS, Web, and Windows. The result was Flokk, which we released (and open-sourced) back in July.

In this post, we’re going to dive into some of the challenges we faced, the discoveries we made, and desktop-specific features that we added.

Flutter: Introducing StatsFl, an FPS monitor for Flutter

As we begin pushing Flutter to more platforms such as Desktop and Web, it is becoming increasingly important to quickly and easily measure performance of your application. While the built-in performance monitor gets the job done, it leaves a lot to be desired in terms of readability and flexibility.

As the old school Flash devs we are, we remember the days when virtually every Flash application around would use the hi-res-stats package by mrdoob (yes, that mrdoob). It was extremely helpful to catch performance issues, and make sure your application was smooth (which in those days, was a solid 24fps!).

Currently nothing like that exists in the Flutter community. To help fill this gap, we’ve created StatsFl! Available now on pub.dev: https://pub.dev/packages/statsfl

Flutter: Simplify Platform & Screen Size Detection

In the never-ending quest to reduce boilerplate and DRY up our code in Flutter, we have noticed that using the MediaQuery class can be a bit cumbersome, and it’s also missing a couple of key pieces of information.

The issues we see are:

  • MediaQuery.of(context) is a bit verbose on its face
  • Checking for orientation especially is too long:
    bool isLandscape = MediaQuery.of(context).orientation == Orientation.landscape
  • There is no diagonal size parameter, so you can’t easily get the true screen size of the device, helpful for determining your form factor
  • There is no way to get the size in inches, which can be useful when thinking about breakpoints (for most people, 4.5″ is easier to picture, than 720 logical pixels)

To that end, we have small Screen helper class, that we use across all our new projects:

Google, Adobe, gskinner | Flutter Interact ’19

Flutter is a mobile UI toolkit that combines fast development, expressive and beautiful UIs, with native performance. To test-drive the platform, Grant Skinner & Mike Chambers recently built Redrix: a mobile companion app for Destiny 2.
