Compose 中使用livedata 、viewmodel、協程、獲取context

livedata轉換成compose 的state，使用需要添加compose livedata的依賴

@Composable
fun StatisticsPage() {
	val dataList by viewModel.dataList.observeAsState(listOf())
}

// compose livedata相關
implementation "androidx.compose.runtime:runtime:$compose_version"
implementation "androidx.compose.runtime:runtime-livedata:$compose_version"

compose組件中獲取context

@Composable
fun StatisticsPage() {
	val context = LocalContext.current
}

compose組件中獲取viewmodel

@Composable
fun StatisticsPage() {
	val viewModel: StatisticsViewModel = viewModel()
}

compose 中使用協程

@Composable
fun StatisticsPage() {
	 val scope = rememberCoroutineScope()
}
