CompositesAI

Note: This repository was previously known as swiftcomp-flutter and the app as SwiftComp. It was renamed to CompositesAI to better reflect the AI-first direction of the project.

CompositesAI is an AI-powered platform designed specifically for the composites engineering industry. Ask questions about material design, calculations, and process optimization in natural language — and get instant, expert-level answers.

The app is available for iOS, Android, and the web at compositesai.com.

Features

• AI chat assistant for composites engineering — ask anything and get domain-specific answers instantly.
• Voice input — dictate questions hands-free.
• Image and file attachments — add context to your conversations.
• Lamina stress/strain calculator for a single layer with arbitrary fiber orientation.
• Lamina engineering constants calculator.
• Laminate stress/strain calculator.
• Laminate plate properties calculator, including ABD matrices.
• Laminate 3D properties calculator.
• UDFRC rules-of-mixtures calculator for unidirectional fiber-reinforced composites.
• Account flows for sign in, sign up, password reset, profile settings, and provider sign-in.
• Localized UI for English, Simplified Chinese, and Traditional Chinese.

Tech Stack

• Flutter and Dart
• Provider for app state
• GetIt for dependency injection
• Local packages for domain, data, infrastructure, and shared UI components
• composite_calculator for composite mechanics calculations
• speech_to_text for voice input
• image_picker for photo and file attachments
• Fastlane metadata and lanes for mobile release workflows

Requirements

• Flutter stable. CI currently uses Flutter 3.41.7.
• Dart >=3.3.0 <4.0.0.
• Xcode and CocoaPods for iOS builds.
• Android Studio or Android SDK tooling for Android builds.

The repository includes an .fvmrc that tracks the Flutter stable channel. If you use FVM:

fvm install
fvm flutter pub get

Getting Started

1. Clone the repository:

git clone https://github.com/banghuazhao/CompositesAI-flutter.git
cd CompositesAI-flutter

2. Create local configuration files as needed. At minimum, local development and CI expect a .env file to exist:

touch .env

The app also declares msal_config.json as an asset for Microsoft authentication. Keep environment-specific credentials out of commits.

3. Install dependencies:

flutter pub get

4. Run the app:

flutter run

Select an iOS simulator, Android emulator/device, or supported web target when prompted.

Quality Checks

Run the same checks used by CI:

flutter analyze --no-fatal-infos --no-fatal-warnings
flutter test
