Make initial state setup

[distivi]

Hi there, cool library! Thanks for that.

For my use case would be super nice to have initial state setup before actually presenting the dialog.

Basically what I need in method CropState put my custom properties:

internal fun CropState(
    src: ImageSrc,
    transform: ImgTransform =  ImgTransform.Identity, // add
    shape: CropShape = RectCropShape, // add
   // ... here the rest of parameters like aspectLock, initialAspectRatio, region etc.
    onDone: () -> Unit = {},
): CropState = object : CropState {
    val defaultTransform: ImgTransform = transform  // modify
    val defaultShape: CropShape = shape // modify
    val defaultAspectLock: Boolean = false
    override val src: ImageSrc get() = src
    private var _transform: ImgTransform by mutableStateOf(defaultTransform)
    override var transform: ImgTransform
        get() = _transform
        set(value) {
            onTransformUpdated(transform, value)
            _transform = value
        }

    val defaultRegion = src.size.toSize().toRect()

Or maybe having separate data class with initial values, then it could be used in reset function as well.

Thanks for the suggestion. Currently, the CropState constuctor function is not part of the public api, also ImageCropper creates the instance internally. I guess in a future release you would have the option to pass your own CropState to ImageCropper::crop.

In the meantime you can do something like this

val cropState = imageCropper.cropState 
LaunchedEffect(key = cropState != null) {
    cropState?.let { state ->
        state.shape = TriangleCropShape
        state.aspectLock = true
    }
}
//.....
if (cropState != null) ImageCropperDialog(state = cropState)

Which would allow you change anything you want and would only be called once before the crop dialog is shown Hope that helps !

Hope this coming soon. And give you a big thanks for the plugin
