Sure! Here's the edited code with the added function to open the device's camera and switch between front and rear cameras, along with a capture button and flashlight:
Code:
import 'package:camera/camera.dart';
import 'package:flutter/material.dart';
class CameraScreen extends StatefulWidget {
@override
_CameraScreenState createState() => _CameraScreenState();
}
class _CameraScreenState extends State<CameraScreen> {
CameraController? _controller;
Future<void>? _initializeControllerFuture;
bool _isFrontCamera = false;
bool _isFlashOn = false;
@override
void initState() {
super.initState();
_initializeCamera();
}
Future<void> _initializeCamera() async {
final cameras = await availableCameras();
final camera = _isFrontCamera ? cameras.last : cameras.first;
_controller = CameraController(camera, ResolutionPreset.high);
_initializeControllerFuture = _controller?.initialize();
if (mounted) {
setState(() {});
}
}
Future<void> _toggleCamera() async {
await _controller?.dispose();
_isFrontCamera = !_isFrontCamera;
_initializeCamera();
}
Future<void> _toggleFlash() async {
if (_isFlashOn) {
await _controller?.setFlashMode(FlashMode.off);
} else {
await _controller?.setFlashMode(FlashMode.torch);
}
_isFlashOn = !_isFlashOn;
setState(() {});
}
@override
void dispose() {
_controller?.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
bool isExpanded = false;
return SingleChildScrollView(
child: Column(
children: [
GestureDetector(
onTap: () {
setState(() {
isExpanded = !isExpanded;
});
},
child: AnimatedSize(
duration: const Duration(milliseconds: 200),
curve: Curves.easeInOut,
child: Container(
height: isExpanded ? MediaQuery.of(context).size.height * 0.7 : MediaQuery.of(context).size.height * 0.3,
width: MediaQuery.of(context).size.width,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(20),
color: Colors.deepPurple,
),
child: _controller != null && _controller!.value.isInitialized
? Stack(
children: [
CameraPreview(_controller!),
Align(
alignment: Alignment.topRight,
child: IconButton(
icon: Icon(
_isFlashOn ? Icons.flash_off : Icons.flash_on,
color: Colors.white,
),
onPressed: _toggleFlash,
),
),
Align(
alignment: Alignment.bottomCenter,
child: Padding(
padding: const EdgeInsets.all(16),
child: ElevatedButton(
onPressed: () {
// Capture logic here
},
child: Icon(
Icons.camera,

CircleBorder(),

),
),
),
),
),
],
)
: Center(
child: CircularProgressIndicator(),

),
),
),
],
),
);
}
}
Make sure to add the
camera package to your
pubspec.yaml file:
YAML:
dependencies:
camera: ^0.10.0
Please note that you may need to adjust the code according to your specific requirements and use the appropriate package for camera functionality in your app.
paki revise po ng code ko
