我正在测试PrimeNG并尝试使用数据表.除了活动,一切都很好.我正在尝试使用Growl在选择行时显示消息(如PrimeNG网站上的Events演示).我目前有这个:

import { Component, OnInit, EventEmitter } from '@angular/core';
import { REACTIVE_FORM_DIRECTIVES } from '@angular/forms';
import { DataTable, Column, Schedule, Growl, Message } from 'primeng/primeng';
import { NameListService } from '../shared/index';

@Component({
  moduleId: module.id,
  selector: 'dash',
  templateUrl: 'dashboard.component.html',
  styleUrls: ['dashboard.component.css'],
  directives: [REACTIVE_FORM_DIRECTIVES, DataTable, Column, Schedule]
})
export class DashboardComponent implements OnInit {

  newName:string = '';
  newLanguage:string = '';
  errorMessage:string;
  names:any[] = [];
  selectedName:any;
  events:any[];
  cols:any[];
  msgs:Message[] = [];

  constructor(public nameListService:NameListService) {
  }

  ngOnInit() {
    this.getNames();
    this.cols = [
      {field: 'id', …

我从How to create a checkbox using listview 中获取了以下代码，它在选中一个项目时检查所有项目。我如何修复代码以不检查所有项目？

class CheckBoxInListView extends StatefulWidget {
  @override
  _CheckBoxInListViewState createState() => _CheckBoxInListViewState();
}

class _CheckBoxInListViewState extends State<CheckBoxInListView> {
  bool _isChecked = false;

  List<String> _texts = [
    "InduceSmile.com",
    "Flutter.io",
    "google.com",
    "youtube.com",
    "yahoo.com",
    "gmail.com"
  ];

  @override
  Widget build(BuildContext context) {
    return ListView(
      padding: EdgeInsets.all(8.0),
      children: _texts
          .map((text) => CheckboxListTile(
                title: Text(text),
                value: _isChecked,
                onChanged: (val) {
                  setState(() {
                    _isChecked = val;
                  });
                },
              ))
          .toList(),
    );
  }
}
