Major error occurs when trying to access the rawImageData #62

Closed Letalus closed 3 years ago

Letalus commented 3 years ago

There is following issue. As a default within the ExtendedImage.file the cropAspectRatio is ratio9_16. (screenshot 1) Screenshot 2021-04-19 at 10 05 14

When the user switches to the ratio CropAspectRatios.original everything works fine (see screenshot 2) Screenshot 2021-04-19 at 10 04 43

Now when I try to crop the image to the 9_16 format I run the cropImageDataWithNativeLibrary. This now throws me following error: Unhandled Exception: 'package:extended_image_library/src/extended_image_provider.dart': Failed assertion: line 38 pos 7: 'rawImageDataMap.containsKey(this)': raw image data is not already now! and stack: #0 _AssertionError._doThrowNew (dart:core-patch/errors_patch.dart:46:39)

Funny fact, if I don't change the aspect Ratio of the image there is of course no cropping and therefore there is also no error.

My question now is, what does this error mean ( 'rawImageDataMap.containsKey(this)': raw image data is not already now! and stack)? This error occured since this cache mechnism has been included.

Hi, this is not the scope of this library, you can go to extended_image to ask questions.
