Android Compose Material3 ModalNavigationDrawer 抽屉的使用（处理了一些坑）

val drawerState = rememberDrawerState(initialValue = DrawerValue.Closed)
val scope = rememberCoroutineScope()ModalNavigationDrawer(drawerState = drawerState,drawerContent = {// 处理 Back 事件BackHandler(drawerState.isOpen) {scope.launch { drawerState.close() }}// requiredWidth 重置抽屉宽度为指定值，但是不能过大ModalDrawerSheet(modifier = Modifier.requiredWidth(320.dp)) {// 抽屉内容}},// 仅在抽屉打开时允许手势开关抽屉，防止手势冲突gesturesEnabled = drawerState.isOpen
) {Scaffold(modifier = Modifier.fillMaxSize(),topBar = {TopAppBar(navigationIcon = {// 打开抽屉的按钮IconButton(onClick = {scope.launch { drawerState.open() }}) {Icon(imageVector = Icons.Default.Menu, contentDescription = "打开抽屉")}})}){// 页面内容}  
}
