Как я могу получить текущую продолжительность из медиаплеера для отображения на индикаторе выполнения песни? ⇐ Android

[Anonymous]

Я испробовал все возможные шаги, но дал значение только один раз, я хочу, чтобы оно обновлялось каждую секунду. это мой код, где я делаю неправильно?
я хочу внедрить слайдер прогресса для музыки, кто-нибудь может мне помочь?
здесь я использую библиотеку слайдеров, диапазон которой вы принимаете в этой библиотеке: от текущей позиции до общей продолжительности.
data class MusicPlayerStates(
var playingSongCurrentPosition: MutableState = mutableIntStateOf(0),
var playingSongDuration: MutableState = mutableIntStateOf(0),

//other code
)

fun onEvent(event: MusicPlayerUiEvents) {
when (event) {

is MusicPlayerUiEvents.PlaySong -> {
mediaPlayer?.let {
if (it.isPlaying) {
mediaPlayer?.stop()
mediaPlayer?.reset()
_musicPlayerState.update { state ->
state.copy(
playingSongCurrentPosition = state.playingSongCurrentPosition.apply {
this.value = 0
},
playingSongDuration = state.playingSongDuration.apply {
this.value = 0
}
)
}
}
}
_musicPlayerState.update {
it.copy(
isSongPlaying = it.isSongPlaying.apply {
this.value = true
}
)
}
mediaPlayer?.release()
mediaPlayer = MediaPlayer().apply {
setDataSource(event.url)
prepareAsync()
}
mediaPlayer?.setOnPreparedListener { mediaPlayer ->
mediaPlayer.seekTo(state.value.playingSongCurrentPosition.value)
mediaPlayer.start()
setSongDuration(mediaPlayer.duration)
updatePlaybackState(mediaPlayer.currentPosition)

Log.d("check for currentD_VM","${state.value.playingSongCurrentPosition.value}")
}

mediaPlayer?.setOnCompletionListener { mediaPlayer ->
// Use for precise updates
mediaPlayer?.stop()
_musicPlayerState.update { state ->
state.copy(
playingSongCurrentPosition = state.playingSongCurrentPosition.apply {
this.value = 0
