Hey @WMariusz thanks for the PR. I was looking the code, how about we keep it as Context only?

We could change BitmapCroppingWorkerJob() to accept Context instead of FragmentActivity and it should work. So we avoid changing it type.

For this to work we would need to make BitmapCroppingWorkerJob a extension of CoroutineScope this is a little trick, if you are not sure how this is done I could try to find a time this week and do. what you think?

Obs: The CI broke, please check the contribution guide so you can use the Ktlint formatter and update the changelog

Take a look now, CI should pass this time.

I thought about Context + CoroutineScope solution. However i dont know right now how to get CoroutineContext inside view.

You can take a look on my branch, https://github.com/WMariusz/Android-Image-Cropper/tree/feature/migrate-coroutine-scope.

Unpack solution was the fastest way to achive this with minimum impact on codebase.

@WMariusz I was planning to add here the suggestions, but was easier to open a new PR based on yours ^^

Can you please check/review if work for you? #143
