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
They are super cool to look at and appear to be highly performant. The only issue? The examples they’ve provided with the package are pretty hard to follow (coming in at close to 1500 lines!) and there’s no code snippets at all in the README.
But fear not! This package is actually extremely simple to use once you clear away the noise, and can see how it works.
In the never-ending quest to reduce boilerplate and DRY up our code in Flutter, we have noticed that using the MediaQueryclass 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:
