Usage

import 'package:flutter_dual_camera/flutter_dual_camera.dart';

// Check if device supports dual camera
bool isSupported = await FlutterDualCamera.isDualCameraSupported();

// Start camera preview
if (isSupported) {
  await FlutterDualCamera.startDualCameraPreview();
}

// Capture images from both cameras
Map<String, String> imagePaths = await FlutterDualCamera.takeDualPicture();
String wideImagePath = imagePaths['wide'];
String telephotoImagePath = imagePaths['telephoto'];

Notes & Limitations

• This plugin requires a device with dual camera hardware (typically wide and telephoto lenses)
• The plugin currently doesn't support displaying the camera preview in the UI, only capturing images
• For advanced camera UI features, consider using this plugin together with camera UI packages
