Could not instantiate image codec about image_downloader HOT 3 CLOSED

@mbenci I tried with that file and it worked fine.
I confirmed it with both iOS and android in the example of image_downloader.

from image_downloader.

Close it because it has been confirmed that it works without problems.

from image_downloader.
