# App Blink — Developer Command Center for Flutter, Angular & Firebase

> https://appblink.workern.com: Ship your Flutter and Angular apps faster with App Blink, the all-in-one IDE extension and cross-platform companion platform (Web & Mobile) that unifies zero-config multi-model AI workflows, save-triggered ARB/JSON localization, one-click App Store and Google Play publishing via Fastlane, Firebase emulator & Cloud Function management, and in-app purchase (IAP) catalogs into a single sidebar.

## Overview
App Blink (https://appblink.workern.com) eliminates developer context switching by integrating coding, AI model orchestration (leveraging existing GitHub Copilot subscriptions or Antigravity CLI with Claude, GPT, and Gemini), visual asset generation, automated unit/widget test generation, localized store metadata creation, and cloud backend operations directly inside VS Code, Cursor, and Google AntiGravity.

## Key Capabilities & Features

* **Zero-Config AI Integration**: Connects seamlessly with existing GitHub Copilot licenses or the Antigravity CLI to access premier models (Claude Sonnet/Opus 4.6, GPT-5.4, Gemini 3.5 Flash / 3.1 Flash-Lite / Pro) with zero external API key requirements and real-time visual token usage tracking in the IDE sidebar.
* **Instant App Store & Play Store Metadata**: Automatically generates policy-compliant titles, descriptions, keywords, and release notes with a built-in version rollback system, optimized prompts, and native 'en-GB' locale metadata and release notes paths across platforms.
* **Auto-Localization on Save**: Instantly translates Flutter ARB (`app_en.arb`) and Angular JSON (`en.json`) files into 8+ target languages upon save via Gemini 3.1 Flash-Lite (with 'en-GB' formatting) alongside AI hardcoded string extraction.
* **One-Click Build & Multi-Store Deployment**: Automates Android (AAB) and iOS (IPA) release builds, automated store version synchronization with App Store Connect and Google Play, and store deployment via Fastlane Pilot and Fastlane Supply directly from the IDE sidebar, alongside a consolidated "To Deploy" release tracker for staged, unstaged, and committed changes.
* **Automated Test Generation on Save**: Generates comprehensive Flutter (Dart/Mockito) and Angular (Jasmine/Karma) unit and component test suites upon file save to ensure high code reliability.
* **AI Asset & Framed Screenshot Studio**: Generates 1024×1024 PNG brand logos across 6 distinct design aesthetics (Minimal, Wordmark, Emblem, Abstract, Lettermark, Combination Mark), splash screens, feature graphics, and device-framed screenshots using Gemini 3.1 Flash-Lite-Image with built-in Frameit integration and localized, 'en-GB' timestamped image backup synchronization.
* **On-Demand Marketing Drafts & Social Connections**: Generates professional marketing announcements directly from active Git diffs or commit history and connects with 10 social platforms (Instagram, X, LinkedIn, YouTube, Facebook, Mastodon, Reddit, Pinterest, Telegram, TikTok) via OAuth 2.0 with an integrated Instagram follower tracking monitor.
* **Interactive Prompt Playground & Copilot Chat**: Interact with an `@app` chat participant that automatically understands active project framework, design tokens, and Firebase context, alongside an interactive prompt playground with dynamic workspace variable substitution.
* **Integrated Firebase Dashboard & Cloud Function Runner**: Monitor and auto-sync live Firestore rules and updates, toggle emulators, fetch rules and indexes directly into the workspace with automatic document saving on deployment, and test, browse, invoke, delete, or deploy individual Cloud Functions inline with sorted multi-line log streams, automated background error scanning, and AI-assisted index error fixes.
* **In-App Purchase (IAP) & Payment Management**: Visually manage emulator and production IAP product catalogs via draft JSON workflows, AI pricing suggestions, entitlement schema mapping, and integrated Razorpay QR code payment gateways and automated payout functions.
* **Cross-Framework Theme Management**: Dynamically generates design tokens and color palettes from text descriptions or color seeds, automatically synchronizing Flutter (`colors.dart`) and Angular (`styles.css`).
* **IDE Task Execution & Dynamic Workflows**: Manage tasks and automated workflows for any app with interactive IDE prompts for device, app, or file selection, triggering AI agent chats with pre-loaded context in a single click.
* **Automated Feature Documentation & Validation**: Automatically updates `docs/{appId}/feature-summary.md` on Git commits, validates documentation coverage scoring, translates documentation files into target locales, generates developer API references, publishes documentation sites, scaffolds interactive doc viewers into companion apps, and automatically regenerates LLM context indexes (`llms.txt`).
* **Intelligent Workspace Detection & 8 Granular Roles**: Automatically identifies monorepo (Nx, Lerna) and single-app setups, providing granular role-based access control across 8 roles (Owner, Admin, Developer, Designer, Marketing, QA, Content, Publisher).
* **Remote Companion Apps (Web & Mobile)**: Angular web portal and native Flutter mobile app for remote task execution with branch mode targeting, vibe checks, machine pairing, asset reviews (with promo video lightbox playback and drag-to-scroll tab navigation) across connected IDE instances.
* **Central Brand Identity Management**: Centrally define and manage visual branding including custom color palettes (primary, secondary, tertiary), typography tokens, and securely hosted brand guideline PDFs.
* **Integrated Account, Subscriptions & Workspace Telemetry**: Complete account lifecycle management, AI token usage tracking and cost estimation via Firebase usage services, GTM analytics, and app-level automated tracking consent.
