Dynamic Bitmap Images Rendering Issue

[edwin-pixel-1]

Lottie is supported and developed on nights and weekends. Issues from Lottie sponsors will be prioritized.

Checklist

1. My animation doesn't use any unsupported features. ✅
2. I know what part of my animation doesn't work. ✅
3. I have created a simplified version of my animation ❌
4. I have attached the AEP file (as a zip file so it can be attached) that only has the part of the animation that doesn't work. ❌

Describe the bug I have used this library to load json animation file from API, along with multiple images loaded as Bitmap. I have this implementation working perfectly fine using the classic way using XML layout with LottieAnimationView reference... Here an example of this functional working code:

animationView.setAnimationFromJson(animationHolder.jsonAnimation, null)

// serverImages structure: Map<String, Bitmap>?
animationHolder.serverImages?.also { serverImages ->
    animationView.setImageAssetDelegate { lottieAsset ->
        serverImages[lottieAsset.fileName]
    }
}
animationView.playAnimation()

The problem comes now when I tried to do the same but with Lottie Compose... I added each bitmap image as dynamicProperty, but it doesn't work properly. Here it's a code example of it:

val animationHolder by myViewModel.animationHolder.collectAsState()

val composition by rememberLottieComposition(spec = LottieCompositionSpec.JsonString(animationHolder?.jsonAnimation ?: ""), cacheKey = null)

// serverImages structure: Map<String, Bitmap>?
val dynamicPropertyList = animationHolder?.serverImages?.let { serverImages ->
    val propertyList = mutableListOf<LottieDynamicProperty<Bitmap>>()
    serverImages.keys.forEach { key ->
        serverImages[key]?.also { bitmap ->
            val property: LottieDynamicProperty<Bitmap> = rememberLottieDynamicProperty(
                property = LottieProperty.IMAGE,
                keyPath = arrayOf(key),
                value = bitmap,
            )
            propertyList.add(property)
        }
    }
    propertyList.toTypedArray()
} ?: arrayOf()

if (dynamicPropertyList.isNotEmpty()) {
    val dynamicProperties = rememberLottieDynamicProperties(*dynamicPropertyList)

    val progress by animateLottieCompositionAsState(
        composition = composition,
        iterations = LottieConstants.IterateForever,
        clipSpec = clipping,
        isPlaying = true,
        restartOnPlay = true,
        speed = 3F, //TODO: Remove,
    )

    LottieAnimation(
        composition = composition,
        progress = { progress },
        modifier = Modifier
            .padding(vertical = 30.dp)
            .wrapContentHeight()
            .height(230.dp),
        dynamicProperties = dynamicProperties,
    )
}

Even doing all what is supposed to be done, the animation never renders well, doesn't show all the sequence correctly. So, after a lot of debugging and comparing it with the legacy way (xml layout), and trying a lot of workarounds, finally I found a way to solve it... Internally in the Library, in the file LottieAnimation, for the composable method LottieAnimation when it's setting up the drawable, I think it lacks calling drawable.setImageAssetDelegate {...} assigning the right images to the sequence. Would be great to fix this for future usages.
