ASO for App Store & Google Play in one panel — self-hosted, source-available.

Edit, diff and publish your store listings from one panel. AppBoard syncs apps from App Store Connect and Google Play, versions every metadata field with GitHub-style history and rollback, manages screenshots and reviews, and ships an AI assistant for translations and ASO keywords. Runs self-hosted via Docker.

• Listings editor with multi-language drafts and live diffs
• Field-level history with one-click rollback
• Reviews inbox with AI-drafted replies
• Batch publishing to both stores

Embed Unity 3D in Flutter with a typed, testable bridge — lifecycle, AR and CDN asset streaming included.

A Flutter plugin that embeds Unity as a native platform view with a typed, stream-based bridge (JSON or binary protocol), an enforced lifecycle state machine, a readiness guard that never drops messages, and an asset-streaming pipeline built on CDN manifests and Unity Addressables. Supports Unity 2022.3 LTS through Unity 6.

• Typed two-way bridge with broadcast streams
• Binary protocol for high-frequency traffic
• Lifecycle state machine that survives navigation
• sendWhenReady() queues messages until Unity is up

The fastest image resize, crop and compress for Flutter — pure native C, identical on every platform.

An FFI plugin that runs the whole image pipeline (decode → EXIF rotation → crop → bicubic resize → encode) in native C with stb_image, 3-4x faster than Dart image libraries. The same Catmull-Rom bicubic kernel on iOS, Android and macOS matches OpenCV's INTER_CUBIC — perfect for ML preprocessing with built-in tensor normalization.

• 3-4x faster than Dart-based image libraries
• Identical output across iOS, Android and macOS
• ML-ready: tensor normalization, HWC/CHW layouts
• 9 crop anchors and 4 edge-handling modes

Pure Dart DOCX and PDF generation from a single document model — no native dependencies.

Generate (and read) Microsoft Word DOCX and PDF documents from one shared document model: rich text, tables, nested lists, hyperlinks, bookmarks and auto table of contents. Pure Dart with zero native dependencies, so it runs on iOS, Android, Web, macOS, Windows, Linux — including WASM.

• One model, two outputs: DOCX and PDF
• Zero native dependencies — works everywhere, incl. WASM
• Tables, nested lists, hyperlinks, bookmarks, TOC
• DocxReader: read → modify → write round-trips

GPU-accelerated GLSL shader effects for Flutter UI — drop-in widgets, zero dependencies.

Ten ready-to-use shader effect widgets — aurora, fire, glass, glow, pulse, ripple, shimmer, snow, water and waves — each running on the GPU as a GLSL fragment shader. Shaders compile once and cache, cost nothing when disabled, and the core API lets you build your own shader widgets on top.

• 10 drop-in effects: aurora, fire, glass, ripple and more
• GPU fragment shaders — compiled once, cached
• Zero external dependencies, Flutter SDK only
• Zero GPU cost when an effect is disabled

Haptic feedback, vibration and animated widgets for Flutter — the right haptic at the right moment.

Full Android and iOS haptics: semantic UI taps, custom Core Haptics patterns with intensity and sharpness curves, amplitude waveforms and predefined OS effects — plus 8 production-ready animated widgets (sliders, toggles, ratings, slide-to-confirm) that pair each animation with the correct haptic automatically.

• Semantic haptics: impact, notification, selection
• Fluent HapticPattern builder (Core Haptics)
• 8 animated widgets wired to the right haptic
• Ready-made patterns: heartbeat, alarm, success…
