Release notes

What’s New in FlutterFlow - v6.6.56 | April 21, 2026

Features

Child Slots

A new way to build flexible, composable components in FlutterFlow. Child Slots let you declare named “drop zones” inside your components, places where anyone using the component can plug in any widget they want, from a simple Icon to a full Switch, TextField, or nested component.

How to use

• Open component
• Add a parameter: in the properties panel, click Add Parameter and choose Child Widget as the type.
• Name it (e.g. trailing, header, content) and optionally add a description.
• Place the slot in the tree: drag the new slot from the widget palette’s Components & Custom Widgets section to the spot in your component’s layout where the injected content should render. A dashed placeholder appears on the canvas.
• Pass a Component/Widget. When anyone drops an instance of it on a page, they’ll see your slot in the widget tree and can drag any widget into it.

Custom Shaders (+ Claude Skill)

ShaderFill and ShaderWrapper widgets now support custom shader uploads. This means that you can bring your own fragment shaders or use one from https://www.shadertoy.com.

Claude Skill

We’ve created a Claude Skill for you to download to convert ShaderToys Shaders into fragment shaders you can use in FlutterFlow.

Download Claude Skill

Supabase OAuth Integration

Connect your Supabase account via OAuth for a streamlined setup — FlutterFlow handles the authorization and schema import automatically.

New AspectRatio Widget

A new AspectRatio widget is available in the widget palette with preset ratios (1:1, 4:3, 3:2, 16:9, 9:16, 3:4, 2:3), custom value support and variable bindings.

Free Trial For Teams Plans

Free Trials for Team Plans: All team plans (Growth, Business) now offer a free trial on first subscription, with accurate eligibility checking across historical subscriptions.

Improvements

• Radial Gradient support from Designer: Elements pasted from FlutterFlow Designer that use radial gradients are now correctly imported rather than falling back to a flat color.
• Designer-to-FlutterFlow chart conversion: Bar, line, and pie charts created in the Designer now convert into fully functional FlutterFlow chart widgets.
• Radio Button dynamic height: Radio button options now support dynamic height with text wrapping, plus a new option spacing property for controlling gaps between options.
• PDF viewer previews render at significantly higher quality using DPR-aware scaling and lossless PNG format.
• PinCode widget now filters input to digits-only on web and desktop when keyboard type is set to Number.
• Read-only text fields no longer show a functional “clear field” icon.
• Local Run now works offline when Experimental Speed Up is enabled.
• Faster “Publish as Library” page loading for large projects.

31 Bug Fixes

We’ve been hard at work squashing bugs. Here are some highlights:

• Fixed Run Mode crashing on launch.
• Fixed custom files (and their unlocked state) being lost after a branch merge rebuild.
• Fixed library assets (fonts, icons) missing from downloaded code.
• Fixed Android APK builds failing for projects using OneSignal.
• Fixed Supabase OAuth token refresh failing with a “Required parameter: client_id” error.
• Fixed Firebase config files not syncing on Windows.
• Fixed duplicate package dependencies causing project build errors.
• Fixed app event handler code generation producing incorrect function names, which could cause build failures.
• Fixed custom palette colors generating hardcoded hex values instead of referencing your theme colors.
• Fixed property panel briefly showing incorrect widget properties after adding a new widget.
• Fixed a false “Firestore indexes not deployed” error appearing on projects with no composite indexes.
• Fixed Supabase schema import losing element type information for array columns.
• Fixed API requests from external tools (e.g., VS Code extension) being applied to the wrong version of version-pinned projects.
• Fixed marketplace sample app cloning failing with a permissions error.

What do you mean? 🙃

This is a massive update 🔥

Child Slots alone are a game changer — finally bringing real composability to FlutterFlow components.

Also loving the Supabase OAuth and shader support — the platform keeps getting closer to full dev-level flexibility.

Great to see this level of progress 🚀

Thanks for the feature, it’s really helps with the development especially the child slots and aspect ratio thingy

Thank you for all the amazing update. Yet, since then, I haven’t been able to use it due to the FlutterFlow Version out of date - “‘Refresh” didnt work. v.6.3. anyone has the same problem?

Pearl Liu is this for the desktop app or on web?

I think my highlight is…child slots 😄 I really like that it adds so much modularity! Thanks so much team! If I had had that feature earlier…I guess I would have built at least 2 apps completely different 😂

Thanks.

Are you guys going to improve the ‘Agents’ section? As it is, it has very limited use. We need to be able to pass arguments to the agent dynamically. And the models are rather old. MCP maybe?

Вот основные нововведения в FlutterFlow версии 6.6.56, описанные в заметке What’s New in FlutterFlow - v6.6.56:

Главные функции

• Слоты для дочерних виджетов (Child Slots) | Позволяют создавать гибкие компоненты с именованными «зонами сброса». Теперь в компонент можно вставить любой виджет (иконку, текст или другой компонент) прямо при использовании его на странице.
• Кастомные шейдеры | Виджеты ShaderFill и ShaderWrapper теперь поддерживают загрузку собственных фрагментных шейдеров (например, с ShaderToy). Доступен специальный Claude Skill для конвертации кода.
• Интеграция Supabase OAuth | Упрощенный процесс подключения аккаунта Supabase с автоматической авторизацией и импортом схем.
• Виджет AspectRatio | Новый виджет для фиксации соотношения сторон (16:9, 4:3 и т.д.) с поддержкой переменных.

Улучшения

• Дизайнер | Корректный импорт радиальных градиентов и автоматическая конвертация графиков из FlutterFlow Designer в рабочие виджеты.
• Radio Button | Поддержка динамической высоты и переноса текста в вариантах выбора.
• PDF Viewer | Значительное повышение качества рендеринга превью.
• Local Run | Теперь работает в офлайн-режиме при включении «Experimental Speed Up».

Исправления

• Устранено 31 баг, включая критические ошибки: вылеты Run Mode, проблемы с обновлением токенов Supabase OAuth и ошибки сборки Android APK при использовании OneSignal.
