Yes, it is bug. Try like this as workaround:
cropper.SetValue(ImageCropperView.PhotoSourceProperty, img);
This is producing a System.NullReferenceException
error.
This is producing a
System.NullReferenceException
error.
Nope. I tried it. What is in your ImageSource? Can you make repro?
I just rearranged the code. Now instead of passing ImageSource
in cunstructor, i've added an "Pick Image" Button
and using Xamarin.Essentials.MediaPicker
to fetch file from gallery and pass it as PhotoSource
of ImageCropperView
.
This still producing a System.NullReferenceException
error.
Attached a ZIP file below.
Thanks! I'll fix it on the weekend

By the way, I'm inclined to conclude that the Essentials plugin is to blame. Try with Media plugin. Also, try without cropper - will it work with direct picture?(edit: yes, it work) In any case, there is such a bug, I will figure out whether he was involved in this
@jocontacter did you get a chance to look into this?
I want to assign an image source to
cropper.PhotoSource
.But this throw the error : "
Property or Indexer 'ImageCropperView.PhotoSource' cannot be assigned to -- it is read only
".How we can do it?
