expo-image-crop-new-pb v1.0.5

Crop and rotate image without detach your expo project!

Expo.ImageManipulator is only a API without a UI, so you have to build your own UI on top of it, or choose detach your project to use third party linked packages, witch is no so good because a pure javascript Expo project is marvelous!

PRs are welcome...

No more flickering while resizing image mask!

Compatible with Expo SDK 36

Atention: squareAspect was removed on this version and will be add in future versions, if you need it, please stay at 0.2.17
