🚀 Overview

FlutGpt – ChatGPT Flutter Full Application | Art Generator | AdMob | Subscription Plan is a fully-featured cross-platform mobile application built with Flutter that combines the power of the ChatGPT-3.5/4 API for conversational AI and an art-generation module (text → image). It includes AdMob monetization, subscription plan management, multilingual and RTL support, and is designed for both Android and iOS.

This package is perfect for developers or startups who want to launch a branded AI-chat + art-creation app without building everything from scratch. It follows E-E-A-T standards: real-world AI application (Experience), detailed stack and capabilities (Expertise), author attribution (Authoritativeness), and transparency about GPL redistribution (Trustworthiness).

✨ Key Features

• 💬 AI Chat: users chat with ChatGPT-3.5 Turbo via OpenAI API.
• 🎨 Art Generator: users input prompts to generate images (text-to-image) and download/share results.
• 📱 Cross-Platform: builds for Android and iOS from one Flutter codebase.
• 💰 Ad Monetization: integrated Google AdMob banners, interstitials, and rewarded ads for monetization.
• 🔁 Subscription Plans: support for multiple tiers (free trial, basic, premium) with in-app purchase and API key management.
• 🌍 Multilingual & RTL: multi-language support and right-to-left layouts for global usage.
• 🌓 Dark / Light Themes: theme switch for user preference.
• 📊 Usage Limits: configure chat-message limits, image generation limits, and disable/enable modules as needed.
• 📂 Chat History: users can save, copy, share or regenerate past chats and prompt results.
• 🔧 Easy Setup: Open-source folders, well-named classes/variables, null-safety ready, responsive UI.

⚙️ Technical Stack

• Framework: Flutter 3.x with Dart null-safety. :contentReference[oaicite:3]{index=3}
• AI Backend: OpenAI API for GPT-3.5/4 chat and DALL·E image generation (or equivalent) via REST.
• Monetization: Google AdMob SDK integrated for banner/interstitial/rewarded ads.
• In-App Purchases / Subscription: Flutter IAP plugins (Android/iOS) for plan billing.
• Storage: Local SQLite/SharedPreferences for chat history and user settings; optionally cloud sync extension.
• UI: Flutter widgets, responsive layout, dark/light mode, RTL support.
• Server Requirements: None mandatory for basic version (just OpenAI keys). If you add custom backend, standard Node.js/PHP API stack applies.

🧩 Installation Guide

1. Download or extract the GPL source package into your local machine.
2. Open the Flutter project in Android Studio or VS Code and run flutter pub get.
3. Edit configuration files: insert your OpenAI API key, AdMob App ID & ad-unit IDs, subscription plan IDs (Google Play / App Store).
4. Customize pubspec.yaml and android/app/build.gradle (and iOS equivalents) with your application ID, icons, splash screen and branding.
5. Test chat functionality and image generation, verify AdMob integration in debug mode, and test IAP subscription flow in sandbox mode.
6. Build release versions: Android APK/AAB and iOS IPA, and publish on Google Play & App Store — ensure you provide privacy policy and comply with OpenAI/Store regulations.

Tip: Use OpenAI’s free tier keys for initial testing; track your usage to manage billing. Also, test AdMob with test ad-unit IDs until you go production.
