Camera Grid Example

This example demonstrates how to use the Camera Grid package with the Flutter camera plugin.

Getting Started

1. Ensure you have Flutter installed on your machine.
2. Clone this repository or copy the example code.
3. Run flutter pub get to install dependencies.
4. Connect a device or start an emulator.
5. Run flutter run to start the app.

Code Example

import 'package:camera/camera.dart';
import 'package:camera_grid/camera_grid.dart';
import 'package:flutter/material.dart';

import 'widgets/camera_wrapper.dart';

late List<CameraDescription> _cameras;

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  _cameras = await availableCameras();
  runApp(const CameraApp());
}

class CameraApp extends StatefulWidget {
  const CameraApp({super.key});

  @override
  State<CameraApp> createState() => _CameraAppState();
}

class _CameraAppState extends State<CameraApp> {
  late CameraController controller;

  @override
  void initState() {
    super.initState();
    controller = CameraController(_cameras[0], ResolutionPreset.max);
    controller.initialize().then((_) {
      if (!mounted) {
        return;
      }
      setState(() {});
    }).catchError((Object e) {
      if (e is CameraException) {
        switch (e.code) {
          case 'CameraAccessDenied':
            // Handle access errors here.
            break;
          default:
            // Handle other errors here.
            break;
        }
      }
    });
  }

  @override
  void dispose() {
    controller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    if (!controller.value.isInitialized) {
      return Container();
    }
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: Scaffold(
        backgroundColor: Colors.blueGrey,
        body: CameraWrapper(
          child: CameraPreview(
            controller,
            child: const CameraGrid(),
          ),
        ),
      ),
    );
  }
}

This example initializes the camera, displays a camera preview, and overlays it with the Camera Grid.

Dependencies

Make sure to add these dependencies to your pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter
  camera: ^latest_version
  camera_grid: ^latest_version

Replace latest_version with the appropriate version numbers.

Additional Notes

• The CameraWrapper widget is not included in this example. Ensure you have this widget implemented or replace it with appropriate camera initialization logic.
• Handle camera permissions and errors as needed for your specific use case.

For more details on customizing the Camera Grid, refer to the main package documentation.
