How to capture an image using ImagePicker in Kotlin Android

How to capture an image using ImagePicker in Kotlin Android.

Here is a step-by-step tutorial on how to capture an image using ImagePicker in Kotlin for Android:

First, open your Android project in Android Studio.
Make sure you have the ImagePicker library added to your project. To do this, open your app-level build.gradle file and add the following dependency:
```
implementation 'com.github.dhaval2404:imagepicker-support:1.4'
```
Sync your project to download the library.
Open the activity or fragment where you want to capture the image.
Declare a constant variable to define the request code for capturing the image:
```
private val REQUEST_IMAGE_CAPTURE = 100
```
Create a button or any other UI element to trigger the image capture process in your layout XML file.

In your activity or fragment class, initialize the ImagePicker library:

private lateinit var imagePicker: ImagePicker

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    imagePicker = ImagePicker(this)
}

Implement the click listener for the button or UI element to trigger the image capture:
```
button.setOnClickListener {
    captureImage()
}
```

Create a function to handle the image capture process:

private fun captureImage() {
    imagePicker.setImagePickerListener(object : ImagePickerListener {
        override fun onImagePicked(imageFile: File?, source: ImageSource) {
            // Handle the captured image here
            if (imageFile != null) {
                // Do something with the captured image file
            }
        }

        override fun onCanceled() {
            // Handle if the image capture process was canceled
        }

        override fun onPermissionDenied() {
            // Handle if the required permissions were denied
        }
    })

    // Start the image capture process
    imagePicker.showChooser()
}

Finally, handle the result of the image capture process in the onActivityResult method:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK) {
        imagePicker.onActivityResult(requestCode, resultCode, data)
    }
}

That's it! You have now implemented the image capture functionality using ImagePicker in your Kotlin Android project. When the user clicks the button, the image capture process will be triggered, and the captured image will be available in the onImagePicked method for further processing.
