Checkbox in Xamarin IOS and Android

Use Image and set checked and unchecked image to it source dynamically 


Design Side: 

<Image Source="unchecked_checkbox" >
     <Image.GestureRecognizers >
         <TapGestureRecognizer Tapped="TapGestureRecognizerForCheckStaff" />
       </Image.GestureRecognizers>
</Image>

Coding Side:

private void TapGestureRecognizerForCheckStaff(object sender, EventArgs e)

{
 
    Image img = (Image)sender;
    var selectedImage = img.Source as FileImageSource;
 
    if (selectedImage.File == "unchecked_checkbox")
    {
        // perform action checkbox is checked;
        img.Source = "checked_checkbox";
    }
 
    if (selectedImage.File == "checked_checkbox")
    {
        // perform action when checkbox is unchecked
        img.Source = "unchecked_checkbox";
    }
 
}
