Please say clearly. How do you want to crop that image?! Is it like, the user will be cropping that image?
Or
Do you want, like, all images should get cropped in particular dimension, and are set to as image to any component, automatically?

Yes, the user will crop the image.

So, what issue are you facing in doing that? There are many available extensions for cropping.
One of them is made by @Atom_Developer .

actually, I don't understand his crop view extension because that is manual cropping by given numbers in input. But, I want a ball drag cropping in rectangle form. So I do not find this there. And I found another I think taifun extension or I do not remember that was taking images from list picker...but I want the image from firebase should be taken.

if you can help in building a sample aia for me that would be a great help.

  1. Image is stored in firebase.
  2. Image is displayed in mit app screen.
  3. cropped image is further saved

So, what problem do you have?
Fetch images and store them in a list. And use the images wherever you want.

The image tag is "photo1.jpg".
Still cannot see.

Your aia is of no use whatsoever. In the other topic you said you could successfully download a file from firebase storage. Why are you now unable to do so ?

Why not use the web component to download your file from firebase, this is much more transparent...
