Our Flutter UI is now fully compatible with the latest Flutter version (3.41). We've put in the work to ensure you have full access to all the newest features Flutter has to offer.

During this process, we noticed that json_dynamic_widget is no longer being actively maintained. (We completely understand the developers' reasons, but as you know us: "Impossible" isn't in our vocabulary.)

That's why we've pivoted our implementation to the officially Google-supported solution: Remote Flutter Widgets (rfw). This brings us much closer to the Flutter core, as widgets can now be used directly in the definition file. This makes everything significantly more readable. Furthermore, there's a massive performance boost to be gained by saving templates in binary format - which we already support! In a direct comparison, rfw wins by a landslide; even with large datasets, everything remains buttery smooth. The unexpected switch has already paid off!

Why didn't we use rfw from the start? Simply because not everything was production-ready when we first tested it, and json_dynamic_widget was performing exceptionally well at the time.

This new version isn't just a compatibility upgrade; it's packed with new features:

• Copy-to-clipboard button in editors (optional)
• Biometric/PIN security (per app, per screen, or per button press)
• Title bar styling (e.g., matching screen colors)
• Customizable icons
• Client-side data encryption
• Empty state info text for menus
• Geo-location access with alerts if location services are disabled
• Caching for small images
• Binary data types are now natively recognized
• Password input with quality indicators (optional)
• Toggle visibility for password inputs (optional)
• Multi-factor authentication fixes and a fresh new look
• Background images for masks or menus via API
• Safe Area color customizable via API
• Request reduction for better efficiency
• Full support for all FontAwesome and Material Icons (by name)

We'll be diving deeper into these features over the coming weeks, but for now: it's just awesome!

This is a highly specialized capability, but incredibly powerful. If you're building something like a password manager that syncs credentials across devices, this feature is a game-changer. Passwords never appear in plaintext on the server - even if someone were to gain direct database access due to a security flaw, they'd only see encrypted blobs.

How does it work?

You simply mark the columns you want encrypted:

The corresponding database column must use a binary data type (not text).
That's literally all the setup required.

When the user opens the screen in your app, they'll be prompted for a token. This token is stored securely on the device, never displayed, and used solely for encryption and decryption. Each application can use its own token. You can also delete the token to force re-entry whenever needed.

How it looks like?

Enter token

We tried to improve our picklist = combobox = linked cell editor visually. And the result is so cool.

We played around with different styles like bottom sheet and popup. A bottom sheet is very common on iOS but not on Android devices. A popup is a usual method.
Our current implementation is a popup but it looks like a dialog. It's not bad but not cool enough.
The visual difference is big but it's always the same control.


Some impressions

Every video first shows the good old linked cell editor = combobox = picklist and then a new variant of the same editor.

We support following style names:

• f_as_dialog
• f_as_bottomsheet
• f_as_popup

Styles for popup animation:

• f_popup_jump
• f_popup_fade_in_bounce (default)
• f_popup_fade_in_down
• f_popup_fade_in_roll_down

As usual, code is available in our github repo.

It's now flutter 3.35 compatible, supports Android' 16KB Page size and is ready for Android SDK 36.

We’ve invested a lot of time in improving stability and performance. Layout rendering should now operate somewhat faster than before. Additionally, we’ve implemented push and deep links in a way that allows the application to update its display using pure parameters. For example, it’s now possible to update individual fields or open entire screens and select specific data records within them.

How it works?

Deep link example

The app runs on a real device. It has a simple screen with a button which will send an email with two links in it. The first will open the app and sets an application parameter. This parameter will be shown as text of a text field. The second link will open a specific screen and scrolls to a specific record.

Our implementation of native push:

Native push

The app receives a push message while running and shows a local notification. If you tap the notification, the app will be opened as well. In this demo, we don't tap the notification.

The project, as always, can be found on github.

We’ll be updating our VisionX Previewer app in the next few days and releasing it in the stores.

In short, it's development workspace in the cloud.
Not interested because cloud development environments are not new?
Stop reading and have a nice day

IDX is different!
It's still beta, but it's so cool and it already works. The cool thing is the architecture and the visions behind it.

We tried different cloud dev environments in the past but IDX is the first which worked like expected. One click and everything will be up and running, super fast, easy to manage (because it just works).

Our use-case is simple. Create a mobile demo app with Flutter UI like our example app.

It was super easy because copy/paste of source files was enough. Here's the result:

Flutter UI Android preview

Flutter UI Web preview

To be honest, it wasn't possible to develop without manual configuration because supported flutter version was too old. But a simple

fixed this problem. The Android emulator preview had some problems and didn't work at first but it suddenly worked. We have no idea why, but IDX is beta. The overall performance is not super fast but the IDE part itself is fast enough. The preview and build could be better. Also the Android simulator integration lacks.

But if everything would be configured by a custom template, your online IDE is ready in 30 seconds - ready to work.

For us it's not a replacement for desktop development but it's perfect for collaboration or if you need complex environments e.g. docker, databases. It makes sense to create a development environment in some seconds and share the environment with your team or just to provide a development environment for Low-Code citizen developers. Not every citizen developer has the skill to configure a development environment. But a click on a link and modifying existing files is not a problem.

If you're interested, just try out IDX on your own.

It's a performance and feature release for flutter 3.24.

The new version fully supports table cell formatting (Cell profiles), fixed table cell size calculation, improved image loading and caching (no more flickering), supports full-screen content without safe are (optional), contains new date and time picker components and comes with updated dependencies.

With next version we will use flutter 3.27 and later.

A full changelog is available here and information about 3.2.0.

It's a small feature release for dark mode support.
