If you’ve ever dreamed of building your own social media platform with Flutter, you know the hardest part is setting up all the moving pieces: authentication, profiles, posts, comments, moderation, and maybe even monetization.

That’s exactly where Moonbase comes in. Created by Mitch Koko, Moonbase is a complete open source Flutter app template for building Reddit-style apps. It’s production-ready, structured with clean architecture, and comes packed with essential features to get you started.

🚀 Key Features

🔐 Authentication – Email, Google, and Apple sign-in built in.

📱 Social Platform – Users can post, comment, and interact.

🛡️ Content Moderation – Includes moderation tools and user blocking.

💰 Monetization – Subscription support via RevenueCat.

🏗 Clean Architecture – Built with the BLoC pattern for maintainability and scalability.

This means you don’t just get a design mock-up — you get a fully functional app template that you can extend into your own social platform.

📜 License

Moonbase is open source and licensed under MIT, making it easy to use in personal or commercial projects.

This package is a specialized UI toolkit for apps built in the Omarchy ecosystem, a minimalist Arch Linux configuration created by DHH. If you’re into terminal-inspired design and want your apps to blend seamlessly with a tiling, keyboard-first environment, this package is built for you.

Why Flutter Omarchy Is Interesting

🖤 Terminal Aesthetic – Widgets styled after terminal UIs.

🎨 Dynamic Theming – Automatically picks up colors from Alacritty configs and Walker CSS, just like Omarchy itself. Change your terminal colors → your Flutter app updates in real-time.

🖥️ Cross-Platform – While optimized for Linux/Omarchy, it gracefully falls back to a Tokyonight theme on Windows, macOS, Android, iOS, and Web.

🔧 Widget Set – Includes terminal-flavored components like OmarchyButton, OmarchyCheckbox, OmarchyNavigationBar, OmarchyTabs, OmarchyStatusBar, and more.

🖋 ANSI Colors – Theming integrates with AnsiColor enums for precise terminal-style color palettes.

Whether you want to experiment with AI, integrate different providers, or just have a polished Flutter chat app to learn from, Kelivo has you covered.

🚀 Key Features That Stand Out
🎨 Material You Design – Dynamic theming for a modern Android 12+ look.
🌙 Dark Mode – A clean dark theme that’s easy on the eyes.
🌍 Multi-language Support – English and Chinese UIs out of the box.
🔄 Multi-provider Support – Connects with OpenAI, Google Gemini, Anthropic, and more.
🤖 Custom Assistants – Build and manage your own AI assistants.
🖼️ Multimodal Input – Chat with images, PDFs, Word docs, and text.
📝 Markdown Rendering – Full support for code highlighting, LaTeX, tables, and more.
🎙️ Voice Features – System-level TTS integration for spoken replies.
🛠️ MCP Support – Model Context Protocol integration for advanced workflows.
🔍 Web Search – Built-in search with multiple engines like Exa, Tavily, Brave, Bing, and SearXNG.
🧩 Prompt Variables – Insert dynamic data like model names and timestamps into prompts.
📤 QR Code Sharing – Share provider configs easily.
💾 Data Backup – Export, restore, and safeguard chat history.
🌐 Custom Requests – Send custom HTTP headers and bodies for flexible integrations.

And of course, it’s built with Flutter’s hallmark cross-platform support, running smoothly on Android and iOS, with HarmonyOS support on the roadmap.

If you’re like me, you love discovering little Flutter gems that push the boundaries of what’s possible. Today I want to share something that blends creativity, design, and Flutter’s rendering power: Paper Heatmap Logo.

This open source demo takes your logo and transforms it into a heatmap-style visualization—a glowing, colorful effect inspired by the Make your logo in the heat map style demo from the Paper team.

The secret sauce? Shaders and colors pulled directly from the paper-design/shaders
repository. By plugging these into Flutter’s rendering pipeline, you can turn ordinary shapes into vibrant, dynamic logos that feel alive.

Meet Proxy Cloud – a modern, feature-packed VPN client built entirely with Flutter. And the best part? It’s completely free and open source.

Here are some highlights:

One-tap VPN connections with real-time monitoring

Subscription management so you can easily import and organize configs

Custom settings for bypassing subnets or tweaking DNS

A full Telegram proxy manager with ping, uptime, and country stats

Handy tools like IP lookup, speed tests, and host checkers

And all of it wrapped in a dark, sleek UI with smooth animations ✨

Meet Nocterm. It’s a powerful new framework that lets you build stunning, modern Terminal User Interfaces, or TUIs, using the Dart language you already know and the Flutter-like patterns you already love.

At its core is a familiar, component-based architecture. If you've ever built a Flutter app, you'll feel right at home. You compose your UI with Components, manage dynamic content with StatefulComponent and setState, and build complex interfaces with ease.

And Nocterm brings Flutter's most beloved, game-changing feature with it: Hot Reload.

That's right. Hot Reload... for the terminal. Change your code, hit save, and watch your command-line application update instantly. This isn't just a convenience; it's a complete transformation of the development workflow for TUIs, enabling rapid iteration that was previously unimaginable.

Laying out your components is a breeze with familiar concepts like Row, Column, and Stack, all backed by a flexible, constraint-based layout system. It even includes a comprehensive keyboard event system with focus management, so you can build truly interactive applications.

The Deck

?️ Mobile multiplayer offline card games aggregator ? ?‍? Written ? in Dart and Flutter ?

The inspiration for “The Deck” came from a situation many of us have experienced. Imagine gathering with friends for a game night, only to realize that nobody has the necessary cards. Frustrating, right? This dilemma sparked the idea of leveraging technology to create a solution.

The primary goal of “The Deck” is to provide a user-friendly and cooperative digital game environment for playing classic games that were usually played with cards on paper. One of the standout features of “The Deck” is its unique ability to assign one device as the “table” (a.k.a. deck). By placing this device in the middle of the group, all players can witness the real-time state of the cards. This adds a new level of immersion making it a truly captivating experience.

Interactive country map

The purpose of this package is to draw an interactive map of a country or region where you can select a region.

It can be used to plot data.

How to install

flutter pub add interactive_country_map

Or go here: pub.dev

Demo

Interaction	Chart

How does it work?

The SVG maps are defined by several <path> tags. Because it's XML, we can define an id for each of them. The IDs are unique and defined by the ISO_3166-2.
When a country is selected, its id is returned.

Docs

Interactive map

Use the InteractiveMap in your code to add an interactive map. Then, choose among the MapEntity enum the map you need.
You can customize the theme of your map using InteractiveMapTheme.

The onCountryChanged will receive the code of the selected country/region. All the codes are defined by the ISO_3166-2.

The library is only returning country codes. It's your role to understand them and adapt your own widgets.

Color mapping

You might want to use different colors for your regions. For instance, all the countries starting with A will be in blue and the ones starting with B will be in red.

Add in your interactive map theme the following code:

mappingCode: {
    ...MappingHelper.sameColor(
    Colors.green.shade300,
    [
        "FR-A",
        "FR-B",
        "FR-C",
        "FR-D",
        "FR-E",
    ],
    )
},

The mappingCode accepts a Map<String, Color> when the string is the region code.
MappingHelper.sameColor is a helper to build your dictionary. It will map a list to the specified color.

Markers

You have the choice between 2 types of markers:

• Marker: use the Cartesian coordinates to place the marker
• GeoMarker (TODO): use the lat/long to place the marker at the correct position on the map

Then, you use a MarkerGroup to gather the markers and give them properties:

MarkerGroup(
    borderColor: Colors.pink.shade600,
    backgroundColor: Colors.pink.shade300,
    markers: [
        Marker(x: 30, y: 40),
        GeoMarker(long: 2.294481, lat: 48.858370),
        Marker(x: 250, y: 340),
    ],
),
