              children: [
                Expanded(
                  child: InkWell(
                    onTap: () {
                      _pickImageFromGallery(onImagePicked);
                    },
                    child: SizedBox(
                      child: Column(
                        children: [
                          Icon(Icons.image, size: 50,),
                          Text('Gallery')
                        ],
                      ),
                    ),
                  ),
                ),
                Expanded(
                  child: InkWell(
                    onTap: () {
                      _pickImageFromCamera(onImagePicked);
                    },
                    child: SizedBox(
                      child: Column(
                        children: [
                          Icon(Icons.camera_alt, size: 50),
                          Text('Camera')
                        ],
                      ),
                    ),
                  ),
                ),
              ],
            ),
          ),
        );
      },
    );
  }

  // Pick image from gallery
  static Future _pickImageFromGallery(Function(File) onImagePicked) async {
    final returnImage = await ImagePicker().pickImage(source: ImageSource.gallery);
    if (returnImage == null) return;
    File selectedImage = File(returnImage.path);
    onImagePicked(selectedImage);
    Get.back();
  }

  // Pick image from camera
  static Future _pickImageFromCamera(Function(File) onImagePicked) async {
    final returnImage = await ImagePicker().pickImage(source: ImageSource.camera);
    if (returnImage == null) return;
    File selectedImage = File(returnImage.path);
    onImagePicked(selectedImage);
    Get.back();
  }
}

2. Show Image Picker Options

To show the options to pick an image from the gallery or camera, use the showImagePickerOption method. You can pass a callback function to handle the selected image.

ImagePickerHelper.showImagePickerOption(
  context,
  (File pickedImage) {
    setState(() {
      selectedImage = pickedImage;
      _image = pickedImage.readAsBytesSync();
    });
  },
);

3. Example Usage

Here is an example of how you can use the package in your Flutter widget:

import 'package:flutter/material.dart';
import 'dart:io';
import 'package:image_picker_helper/image_picker_helper.dart';

class MyImagePickerScreen extends StatefulWidget {
  @override
  _MyImagePickerScreenState createState() => _MyImagePickerScreenState();
}

class _MyImagePickerScreenState extends State<MyImagePickerScreen> {
  File? selectedImage;
  Uint8List? _image;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Image Picker Example')),
      body: Center(
        child: Column(
          children: [
            selectedImage == null
                ? Text('No image selected.')
                : Image.file(selectedImage!),
            ElevatedButton(
              onPressed: () {
                // Use the package to show the image picker options
                ImagePickerHelper.showImagePickerOption(context, (File pickedImage) {
                  setState(() {
                    selectedImage = pickedImage;
                    _image = pickedImage.readAsBytesSync();
                  });
                });
              },
              child: Text("Pick Image"),
            ),
          ],
        ),
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(home: MyImagePickerScreen()));
}
