|
|
### 🔧 Setup Requirements
|
|
|
|
**For Windows Desktop Development:**
|
|
1. Install Visual Studio 2022 Community
|
|
2. Add "Desktop development with C++" workload
|
|
3. Include these components:
|
|
- MSVC v143 - VS 2022 C++ x64/x86 build tools (Latest)
|
|
- Windows 11 SDK (10.0.22621.0)
|
|
- CMake tools for Visual Studio
|
|
|
|
**Quick Commands:**
|
|
```bash
|
|
cd flutter_app
|
|
|
|
# Install dependencies
|
|
flutter pub get
|
|
|
|
# Check setup
|
|
flutter doctor
|
|
|
|
# Run on Windows (after VS setup)
|
|
flutter run -d windows
|
|
|
|
# Run on web (works without C++ components)
|
|
flutter run -d chrome
|
|
|
|
# Build for Windows
|
|
flutter build windows
|
|
```
|
|
|
|
### 🎯 Next Steps
|
|
|
|
**Immediate (Ready to Use):**
|
|
1. **Fix Visual Studio Components** - Install C++ workload for Windows builds
|
|
2. **Test Backend Connection** - Ensure TypeScript backend is running on port 3000
|
|
3. **Run Flutter App** - `flutter run -d windows` or `flutter run -d chrome`
|
|
4. **Verify Features** - Test WebSocket, alerts, charts, vendor table
|
|
|
|
**Short Term:**
|
|
1. **Mobile Testing** - Test responsive layout on Android/iOS
|
|
2. **Performance Optimization** - Test with 50k+ chart datapoints
|
|
3. **Notifications** - Implement native notifications for alerts
|
|
4. **Window Controls** - Add minimize/close functionality for desktop
|
|
|
|
**Long Term:**
|
|
1. **App Store Distribution** - Prepare for Google Play, App Store
|
|
2. **Auto-Updates** - Implement update mechanism
|
|
3. **Advanced Charts** - Add more chart types and interactions
|
|
4. **Settings Panel** - Theme, notification preferences
|
|
|
|
### 📱 Mobile Support
|
|
|
|
The Flutter app automatically supports mobile with responsive design:
|
|
|
|
**Desktop Layout:**
|
|
- Multi-column stats cards
|
|
- Side-by-side panels
|
|
- Full-width charts and tables
|
|
|
|
**Mobile Layout:**
|
|
- Single-column scrollable layout
|
|
- Stacked stats cards
|
|
- Touch-friendly controls
|
|
- Responsive charts
|
|
|
|
### 🔄 Backend Compatibility
|
|
|
|
**100% Compatible** with existing TypeScript backend:
|
|
- Same REST endpoints: `/prices/latest`, `/index/history`
|
|
- Same WebSocket protocol: `/ws/index`
|
|
- Same JSON data formats
|
|
- No backend changes required
|
|
|
