any updates on this issue?

New api AnimatedImageVector from 1.1.0-rc01 still does not support repeat="infinite or -1", when all animations in an avd are set to repeat or -1, the total duration reported by the AnimatedImageVector will become 0.

Would be nice if we can have something like a MutableTransitionState or an animation listener to listen for the end of the animation and restart it. This however does not solve the repeating avd issue.

Am i missing something? I tried compose animation graphics version 1.2.0-beta01. However my avd (in #1) is still not repeating/looping infinitely. Am i doing anything wrong?

val image = AnimatedImageVector.animatedVectorResource(id)
val atEnd = remember { mutableStateOf(false) }
        
SideEffect {
    atEnd.value = true
}
        
Image(
    painter = rememberAnimatedVectorPainter(image, atEnd.value),
    modifier = Modifier
        .wrapContentSize(align = Alignment.Center),
    contentDescription = null
)

It seems that compose animatedVectorImage still does not support infinitely repeating animations. I may be wrong but from this piece of code in the androidx.compose.animation.graphics.vector.Animator class. This function seems to only make the animation repeatable if the repeatCount is > 0.

internal class Timestamp<T>(
    val timeMillis: Int,
    val durationMillis: Int,
    val repeatCount: Int,
    val repeatMode: RepeatMode,
    val holder: PropertyValuesHolder<T>
) {
    fun asAnimationSpec(): FiniteAnimationSpec<T> {
        @Suppress("UNCHECKED_CAST")
        val spec = when (holder) {
            is PropertyValuesHolderFloat -> holder.asKeyframeSpec(durationMillis)
            is PropertyValuesHolderColor -> holder.asKeyframeSpec(durationMillis)
            else -> throw RuntimeException("Unexpected value type: $holder")
        } as KeyframesSpec<T>
        return if (repeatCount > 0) {
            repeatable(
                iterations = repeatCount + 1,
                animation = spec,
                repeatMode = repeatMode
            )
        } else {
            spec
        }
    }
}

However for xml avd, repeatcount is infinitely repeatable if the repeatCount is -1 which causes the animation to not repeat at all.

<!-- Defines how many times the animation should repeat. The default value is 0. -->
<attr name="repeatCount" format="integer">
    <enum name="infinite" value="-1" />
</attr>
