I am having this error

When calling your lib, like this:

                val imageCrop: ImageCrop = ImageCrop(bitmap.value!!)

                // Configure ImageCropView.
                imageCrop.ImageCropView(
                    modifier = Modifier.fillMaxSize(),
                    guideLineColor = Color.LightGray,
                    guideLineWidth = 2.dp,
                    edgeCircleSize = 5.dp,
                    showGuideLines = true,
                    cropType = CropType.SQUARE,
                    edgeType = EdgeType.CIRCULAR
                )

                val croppedBitmap = imageCrop.onCrop()

Yes, bitmap.value is a valid bitmap:
bitmap = {ParcelableSnapshotMutableState@33174} Collecting data...
mColorSpace = null
mDensity = 280
mHardwareBuffer = null
mHeight = 3000
mNativePtr = 525779117632
mNinePatchChunk = null
mNinePatchInsets = null
mRecycled = false
mRequestPremultiplied = true
mWidth = 4000
shadow$klass = {Class@18085} "class android.graphics.Bitmap"
shadow$monitor = -1950744464

This callback is never called

            .onSizeChanged { intSize ->
                cropUtil.onCanvasSizeChanged(intSize = intSize)
            }

And, when this function runs
public fun cropImage(): Bitmap {
The canvas size is 0

[diegoflassa]

I was able to fix it by modifying the calling function to this:

                val imageCrop: ImageCrop = ImageCrop(bitmap.value!!)

                // Configure ImageCropView.
                imageCrop.ImageCropView(
                    modifier = Modifier.fillMaxSize(),
                    guideLineColor = Color.LightGray,
                    guideLineWidth = 2.dp,
                    edgeCircleSize = 5.dp,
                    showGuideLines = true,
                    cropType = CropType.SQUARE,
                    edgeType = EdgeType.CIRCULAR
                )
                Log.i(tag, "After imageCrop.ImageCropView")
                val coroutineScope = rememberCoroutineScope()
                coroutineScope.launch(Dispatchers.IO) {
                    delay(3000)
                    val croppedBitmap = imageCrop.onCrop()
                }

I am not sure of the ideal value of the delay
Its gives time for the

        .onSizeChanged { intSize ->
            cropUtil.onCanvasSizeChanged(intSize = intSize)
        }

To be called

You should update your example

Thank you so much for taking the time to identify this issue and report it. Your feedback is incredibly valuable in helping us improve the library. We are already looking into the issue and will have a fix available soon..
