SearchBookScreen.kt

val myViewModel = SearchBookViewModel()

@OptIn(ExperimentalMaterial3Api::class)
@Composable
fun SearchBookScreen(
    modifier: Modifier = Modifier,
    navController: NavController,
    viewModel: SearchBookViewModel = myViewModel,
    filters: Map<SearchFilterType, FilterOptions> = FILTERS
) {
    val focusRequester = remember { FocusRequester() } 

val searchInputValue = viewModel.searchInputValue.value
val filtersState = viewModel.filtersState

LaunchedEffect(Unit) { this.coroutineContext.job.invokeOnCompletion { focusRequester.requestFocus() } }

Scaffold(
    topBar = {
        Column {
            TextField(
                singleLine = true,

我正在使用primeng confirmDialog，它在我的Angular 10项目中需要confirmationService，但localhost:4200没有显示任何内容，我在Chrome控制台中收到以下错误。

这是我的 app.component.ts。

import { Component } from '@angular/core';
import { ConfirmationService } from 'primeng/api';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
