It’s already been 2 months since our team finished the Flutter Vignette project and gave a talk at Flutter Interact ’19. Throughout the project, we were able to maintain a healthy designer-developer relationship, which was the key to the successful completion of the project. I want to share 5 things that helped us build an effective and efficient collaboration between designers and developers.Continue reading →
One of the big issues with Flutter for Web right now is it’s lack of support for dart.io. This means things like a simple Platform.isAndroid call will cause your web builds to crash on startup. In fact, just including the dart.io package _at all_ will break your app completely.
In cases like this, what is needed is some form of conditional compilation, so we can include the code on some platforms, and exclude it on others.
Some platforms like Unity, have built in platform defines, which let you easily partition sections of code for specific platforms. Unfortunately, this is not so easy to do with Flutter, but it is possible!Continue reading →
As the amount of data in the world increases, so does the need for designers to know how to visualize that data. Since at gskinner we have to work with quite a variety of data sets, I thought it was a good idea to brush up my data visualization skills.
I read Information Dashboard Design by Stephen Few and The Visual Display of Quantitative Information by Edward R. Tufte to get a better understanding of the principles and theories behind data visualization. In this post, I’ll share some valuable take-aways from these books that you can apply to your designs.Continue reading →
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:Continue reading →
One of the most interesting aspects of Flutter, is the way it mixes declarative markup-style code, with imperative business logic style code, all within the same Dart programming language and file. This creates a really nice coupling between interface and function. When compared to editing XAML for UWP apps, or XML for native Android, building interfaces in Flutter can be a very rapid workflow.
While this is really nice from a productivity standpoint, it also manifests as one of Flutters biggest issues…Continue reading →
One of the great things about Flutter, is how you can use composition to combine multiple built-in Widgets, creating unique UI’s very quickly and easily.
Today, we’re going to create a
FlippableBox, which is a double-sided card, that holds two pieces of content and automatically re-sizes to match its content, whenever it’s flipped over.
It will end up looking something like this:Continue reading →
