            ),
          ),
        ],
      ),
    );
  }
}

In this code, I added the flashlight icon button, capture button, and switch camera button inside the Column widget when the camera preview is expanded. These buttons are displayed in a Row widget at the bottom of the camera preview. The onPressed callbacks for the buttons are linked to the respective functions: toggleFlashlight, captureImage, and switchCamera. When the container is tapped, the camera preview expands and the buttons become visible.

paki lagyan ng space yung mga button. at isa pang function na idagdag ay kapag pumindot sa labas ng container, automatic mag sasara ang container at babalik sa dating size nito

            ),
          ),
        ],
      ),
    );
  }
}

In the updated code:

  • The margin property is added to the container to add space around it.
  • The IconButton widgets are replaced with FloatingActionButton widgets for a floating button effect.
  • The Row widget containing the buttons now uses mainAxisAlignment: MainAxisAlignment.spaceEvenly to evenly distribute the buttons with space in between them.

To add a circular icon button or a FloatingActionButton to control flashlight on/off and capture image, you can modify the existing code as follows:

1. Import the necessary packages:
Code: 
import 'package:camera/camera.dart';
import 'package:flutter/material.dart';

2. Declare the necessary variables in the widget class:
Code: 
bool isFlashlightOn = false;
CameraController? _cameraController;
CameraDescription? _currentCamera;

3. In the initState() method, initialize the camera and set the current camera:
Code: 
@override
void initState() {
  super.initState();
  availableCameras().then((cameras) {
    _currentCamera = cameras.first;
    _cameraController = CameraController(
      _currentCamera!,
      ResolutionPreset.high,
    );
    _cameraController!.initialize().then((_) {
      if (!mounted) {
        return;
      }
      setState(() {});
    });
  });
}

4. Add a FloatingActionButton below the Container widget:
Code: 
FloatingActionButton(
  onPressed: () {
    setState(() {
      isFlashlightOn = !isFlashlightOn;
      _cameraController!.setFlashMode(
        isFlashlightOn ? FlashMode.torch : FlashMode.off,
      );
    });
  },
  child: Icon(
    isFlashlightOn ? Icons.flash_on : Icons.flash_off,
  ),
),

5. Handle the capture image functionality in the onTap event of the GestureDetector:
Code: 
onTap: () async {
  if (_cameraController!.value.isInitialized) {
    final image = await _cameraController!.takePicture();
    // Process the captured image as per your requirement
  }
},

6. To switch between the front and rear camera, add a SwitchCameraButton widget below the Container widget:
Code: 
SwitchCameraButton(
  onTap: () {
    setState(() {
      _currentCamera = (_currentCamera == cameras.first)
          ? cameras.last
          : cameras.first;
      _cameraController = CameraController(
        _currentCamera!,
        ResolutionPreset.high,
      );
      _cameraController!.initialize().then((_) {
        if (!mounted) {
          return;
        }
        setState(() {});
      });
    });
  },
),

Here's the modified code with the above changes incorporated:

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

class CameraWidget extends StatefulWidget {
  @override
  _CameraWidgetState createState() => _CameraWidgetState();
}

class _CameraWidgetState extends State<CameraWidget> {
  bool isExpanded = false;
  bool isFlashlightOn = false;
  CameraController? _cameraController;
  CameraDescription? _currentCamera;

  @override
  void initState() {
    super.initState();
    availableCameras().then((cameras) {
      _currentCamera = cameras.first;
      _cameraController = CameraController(
        _currentCamera!,
        ResolutionPreset.high,
      );
      _cameraController!.initialize().then((_) {
        if (!mounted) {
          return;
        }
        setState(() {});
      });
    });
  }

  @override
  void dispose() {
    _cameraController?.dispose();
    super.dispose();
  }

  @override

class SwitchCameraButton extends StatelessWidget {
  final VoidCallback onTap;

  const SwitchCameraButton({Key? key, required this.onTap}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return ElevatedButton(
      onPressed: onTap,
      child: Icon(Icons.switch_camera),
    );
  }
}

In this code, the FloatingActionButton controls the flashlight on/off, the capture image functionality is added to the onTap event of the GestureDetector, and the SwitchCameraButton is used to switch between the front and rear camera. The size of the camera preview is not affected by the buttons.
 
Paki edit naman itong code ko. kapag pinindot ko yung capture image button, hindi nya mapicturan yung image na nakikita sa camerapreview,

eto yung button,
FloatingActionButton(
onPressed: () async {
// Capture image
if (_cameraController != null &&
_cameraController!.value.isInitialized) {
try {
final XFile imageFile =
await _cameraController!.takePicture();
// Do something with the image file
} catch (e) {
print('Error capturing image: $e');
}
}
},

eto naman yung dapat na paglalagyan nya ng image

editor.dart
import 'dart:io';
import 'package:flutter/material.dart';
class EditorPage extends StatelessWidget {
final String imagePath;
EditorPage({required this.imagePath});
Override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Image Editor'),
),
body: Center(
child: Container(
decoration: BoxDecoration(
border: Border.all(color: Colors.black),
),
child: Image.file(
File(imagePath), // Correctly create a File object using the imagePath
),
),
),
);
}
}
 
Based on your code, it seems that you are trying to capture an image using the camera and then display it in the EditorPage widget. However, it seems like you are not passing the captured image path to the EditorPage widget.

To fix this issue, you can modify your code as follows:

1. In the EditorPage widget, add a null check for the imagePath parameter to avoid any runtime errors if it is null.

Code: 
class EditorPage extends StatelessWidget {
  final String? imagePath;

  EditorPage({required this.imagePath});

  @override
  Widget build(BuildContext context) {
    if (imagePath == null) {
      return Scaffold(
        appBar: AppBar(
          title: Text('Image Editor'),
        ),
        body: Center(
          child: Text('No image captured'),
        ),
      );
    } else {
      return Scaffold(
        appBar: AppBar(
          title: Text('Image Editor'),
        ),
        body: Center(
          child: Container(
            decoration: BoxDecoration(
              border: Border.all(color: Colors.black),
            ),
            child: Image.file(
              File(imagePath!), // Correctly create a File object using the imagePath
            ),
          ),
        ),
      );
    }
  }
}

2. Modify the onPressed method of the capture image button to navigate to the EditorPage widget and pass the captured image path as a parameter.

Code: 
onPressed: () async {
  // Capture image
  if (_cameraController != null &&
      _cameraController!.value.isInitialized) {
    try {
      final XFile imageFile = await _cameraController!.takePicture();
      Navigator.push(
        context,
        MaterialPageRoute(
          builder: (context) => EditorPage(imagePath: imageFile.path),
        ),
      );
    } catch (e) {
      print('Error capturing image: $e');
    }
  }
},

With these changes, when you press the capture image button, it will capture the image and navigate to the EditorPage widget, where the captured image will be displayed. If no image is captured, it will show a "No image captured" message.

      Navigator.push(
        context,
        MaterialPageRoute(
          builder: (context) => EditorPage(imagePath: imageFile.path),
        ),
      );
    } catch (e) {
      print('Error capturing image: $e');
    }
  }
},

add ko pa sa function. kapag pinindot ang capture image button. mapupunta sya sa new window which is the editor.dart

To navigate to the EditorPage after capturing the image, you can use the Navigator.push method. Here's how you can modify your code to achieve this:

1. Import the editor.dart file at the top of your file:

Code: 
import 'editor.dart';

2. Modify the onPressed method of the capture image button to navigate to the EditorPage widget and pass the captured image path as a parameter:

Code: 
onPressed: () async {
  // Capture image
  if (_cameraController != null &&
      _cameraController!.value.isInitialized) {
    try {
      final XFile imageFile = await _cameraController!.takePicture();
      Navigator.push(
        context,
        MaterialPageRoute(
          builder: (context) => EditorPage(imagePath: imageFile.path),
        ),
      );
    } catch (e) {
      print('Error capturing image: $e');
    }
  }
},

With these changes, when you press the capture image button, it will capture the image and navigate to the EditorPage widget, passing the captured image path as a parameter. Make sure to update your imports and replace 'editor.dart' with the correct path to your EditorPage file.
 
paki edit naman itong button, ang gusto ko mangyare ay kapag pinindot ko ang button na ito, mag eexpand yung container
OutlinedButton(
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => ProtanopiaPage(), // Replace with your actual screen name
),
);
},
style: OutlinedButton.styleFrom(
side: BorderSide(color: Colors.deepPurple),
backgroundColor: _isButtonClicked ? Colors.deepPurple : Colors.transparent,
),
child: Text('Protanopia'),
),

],
),
),

eto naman yung mag eexpand

SingleChildScrollView(
child: Column(
children: [
GestureDetector(
onTap: () {
setState(() {
isExpanded = !isExpanded;
});
},
child: AnimatedSize(
duration: const Duration(milliseconds: 200),
curve: Curves.easeInOut,
child: Stack(
children: [
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: isExpanded
? ClipRRect(
borderRadius: BorderRadius.circular(20),
child: CameraPreview(_cameraController!),
)
: const Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Icon(
Icons.camera,
color: Colors.white,
size: 48,
),
SizedBox(height: 10),
Text(
'CAMERA',
style: TextStyle(
color: Colors.white,
fontSize: 22,
),
)
],
),
),
),
 
To update the button to expand the container when pressed, you can modify the onPressed function of the OutlinedButton as follows:

Code: 
onPressed: () {
  setState(() {
    isExpanded = !isExpanded;
  });
},

Here's the updated code:

Code: 
OutlinedButton(
  onPressed: () {
    setState(() {
      isExpanded = !isExpanded;
    });
  },
  style: OutlinedButton.styleFrom(
    side: BorderSide(color: Colors.deepPurple),
    backgroundColor: _isButtonClicked ? Colors.deepPurple : Colors.transparent,
  ),
  child: Text('Protanopia'),
),

Make sure that the isExpanded variable is defined and initialized as false in the widget's state.

Then, in the SingleChildScrollView, you can modify the Container's height based on the isExpanded flag. Here's the updated code:

Code: 
Container(
  height: isExpanded
      ? MediaQuery.of(context).size.height * 0.7
      : MediaQuery.of(context).size.height * 0.3,
  // ...
),

This will make the container expand to 70% of the screen height when isExpanded is true, and shrink to 30% of the screen height when isExpanded is false.

Apologies for the confusion. To add the AnimatedSize effect to the Protanopia button, you can modify the onPressed function of the OutlinedButton as follows:

Code: 
onPressed: () {
  setState(() {
    isExpanded = !isExpanded;

},

                      )
                    ],
                  ),
                ),
        ),
      ),
    ],
  ),
)

In this updated code, the Protanopia button is wrapped with the AnimatedSize widget. The onPressed function of the button is also modified to toggle the isExpanded flag. As a result, pressing the button will trigger the AnimatedSize effect and expand or collapse the container with a smooth animation.
