Open-source Android and iOS app development framework Flutter was created by Google, with Flutter’s first stable version being released in December 2018.
Flutter is an open-source project, designed for fast, simple programming with native-like performance. In addition, to replace JavaScript, Flutter uses Dart.
And now, Flutter for the web has been released and is stable. This is wonderful news for web designers, who can now construct highly secure and appealing websites, in addition to being able to publish Flutter mobile apps to the web using the same codebase.
Aside from this, Flutter is a design framework for dynamic user interface elements — the richness and interactivity of its user interface makes it suitable for online applications.
Flutter introduced an early adopter program in 2019 for businesses that were ready to create using the web capabilities provided by Flutter’s platform. Flutter had piqued the attention of one of those early adopters, and Supernova wanted to use it to create a collaborative design system platform for the web.
Testing the code and choosing an appealing design with basic functionality is a collaborative effort.
The designers produce tool and component designs using vivid colors, patterns, and basic tools. Numerous upgrades ultimately reveal the final outcome. Hence, design systems are continually evolving.
Numerous designs are now compatible with top software on many platforms. These designs need end-to-end encryption.
A variety of components and tools contribute to product creation and growth, so designers are always perfecting strategies to make safe encryption easy to use.
Supernova lets you quickly and easily obtain comprehensive, organized information on any design system in any of your exporting designs.
A single active design system is described in the Model for Accessing the Data Design System. This means that you may run the exporter and produce one set of outputs, then open another design system and generate a completely different set of outputs — all while still utilizing the same exporter.
You get access to the data in the design system through predefined functions that abstract away any complexity related to data downloading and resolution.
At the time of writing, the following model pieces are available. Additionally, each category has a comprehensive list of strategies for getting design system data:

Both teams are distinct and operate independently. Here is an explanation of how the Supernova system works:
This team creates eye-catching elements using Figma’s design methodology. The Figma design tool combines all design styles.
The design generated is a unique coding converter. The procedure is safe, encrypted, and cannot be replicated. They upgrade the designs with increased automation options.
The data is automatically updated and synchronized. The system is meant to automatically update new versions using hooks. Individual codes are used to export design tokens. It avoids flaws and produces exporters for many design platforms.
Style, assets, and designs of diverse automation engines are managed by unique codes.
Now that the code is done, the design phase begins. The Supernova design system documentation produces and breaks designs using many tools and components.
Like the codes, the designs are abstract. The supernova color scheme uses distinctive and vivid color tones.
As a result of Supernova’s design system, each department has access to its own technology. In order to provide each team the opportunity to be creative and use the full range of technology, it combines the whole development on a single interface.
Let’s have a look at some of the differences between the teams:
Following user feedback, a web-based version of Supernova was built in response to user requests for a MacOS alternative.
Therefore, the team was intrigued by Flutter because it would allow them to deploy their tool across several platforms using a single codebase — especially given the fact that their tool is more compute-intensive and has more stringent performance requirements than the vast majority of websites.
Flutter provides a straightforward means to get access to the lower-layer rendering engine, rather than having to start from scratch with WebGL and work their way up to it from there.
Using Dart’s web-specific libraries saved them time, because the code preview widget couldn’t be included in HTML; the developers had to use a JavaScript library to highlight the syntax.
Supernova is entirely written in Flutter and Dart. Due to the application’s complex logic, the display layer is developed in Flutter. The developers realized that Dart’s language is crucial for designing and maintaining complex programmes. Dart’s annotation processing and code generation capabilities improved a lot over time.
The Figma data model was rendered using Flutter’s CanvasKit engine. The team picked CanvasKit over building custom WebGL shaders in Flutter. CanvasKit’s higher-level rendering capabilities allow the translation of Figma’s non-standard vector models. The fact that Supernova can handle any font selected by a designer is essential. Both Flutter and the Google Fonts package may download fonts straight from Google’s servers.
After two years in early access, Supernova has introduced a new design system platform that makes use of the Flutter framework.
Supernova now allows you to import all of your Figma creations and utilize them to create Flutter scripts (or any other framework).
You may write documentation that is automatically updated as your design changes by using the automation engine in Supernova’s documentation editor.
Everyone can now make use of Supernova. To get started, go to Supernova website and create an account, as well as provide a link to your Figma design file.
Then, the whole world is your oyster from that point on, so to speak. You may start exporting code for Flutter (or any other framework) right away, or you can acquire the assets for icons so that you can start authoring documentation.
It’s time to get hands-on experience with Supernova. Once your signup is complete, proceed with the next steps to provide information about you and your business.
Once done, you will be presented with the Supernova dashboard as shown below.
You can either create a new color token using the New button visible on top right, or link your existing Figma file using the button in the center.
For the brevity of this article, this demo project has Figma file linked and is now prepared for changes, as you can see below:
Once a Figma file is imported, it is added as a source for your design system (linked). It does not need to be added again — updates from the file can be fetched instead.
Figma files are automatically checked for modifications by Supernova on a regular basis. It’s also possible to get an update on-demand if you’ve made an update in Figma and want to instantly check for changes, or if your Figma file updating mode is set to manual.
Tokens (key/value pairs) are style characteristics for a design system in Supernova — codebases and projects that use your design system may consume them.
On top of the conventional name and value fields, each token has an optional description field. Supernova tokens are worth variable amounts depending on their usage. Tokens with style parameters like color, gradient, and shadow may be imported into your design editor; all other tokens must be created manually.
To edit Supernova tokens:
Additionally, in order to define or edit the custom property for a token, follow the below steps:
Design system data can be transformed into production code through exporters (equivalent to npm packages, for example).
The code it generates and the platforms, technologies, and stacks it targets make each exporter package unique. With the use of templates that are driven by Pulsar, you may adapt the generated code to suit your needs. Pulsar, like Handlebars and Mustache, is a familiar templating language.
When building your own exporters, they will be private by default, and you can later choose to publish the exporter to the marketplace if you feel it would be useful to other developers.
To make use of an exporter, you must install an exporter first in your workspace. Then, the exporter will become available to all the team members of the workspace. You can install an exporter in two ways:
(Note: A step-by-step guide to this process is available here)
Once an exporter is installed, you need to install an VS Code extension to work with Supernova in order to generate your build from it — builds are exporters pointing to specific design systems with a specific version.
It is recommended to use the VS Code extension in order to run exporters and retrieve the production code.
Make sure you have at least one exporter installed in your VS Code extension before configuring the default project exporter. The default exporter may be customized in the Supernova panel, which can be found in the lower-left corner.
To change the default exporter in VS Code, choose Configure Default Exporter and provide the following data:
A directory to which the code should be written will be requested as a final step.
When you set up the default exporter, a new file named supernova.json will appear in the workspace’s root folder. Exporter configuration is included in this file, which is taken up by the VS Code extension.
It is highly suggested that you save this file in your source control, so that all of your team members may access the design system’s data at any time, no matter where they are in the development process.
The button you used to initiate the configuration activity will now say Synchronize current codebase after you’ve set the default exporter. To request new production-ready code, just click on this button. The exporter will download the current design system data and produce the code into the folder you designate. Now that’s convenient!
Exporters are powered by a Supernova templating language called Pulsar. Pulsar allows you to define exactly how the output will look, down to the last character. So from here, you might want to explore more about the Pulsar language.
Technologies are always evolving. Each design is encrypted for safety and coding power, emphasizing unique, innovative, and technologically sophisticated data presentation utilizing bespoke code and frameworks — these aspects together blend technical expertise, artistic flair, and safety.
In order to fine-tune Supernova’s security, choices, and performance while still in the early stage, they have limited access to a fraction of the system’s functionality.
However, as Supernova evolves, you’ll be able to get your hands on a wide range of design system aspects. You can join the Supernova community on Discord here.
There is no longer a requirement for your team to transition between tools or manage unique procedures and interfaces when using Supernova. Everything can be automated in a manner that is consistent with the way you now operate.
