How to add items click listener to ListView in Flutter

In this Google flutter code example we are going to learn how to add items click listener to ListView in Flutter.

The code is based on flutter version 1.0.0

Main.dart (App entry point)

import 'package:flutter/material.dart';
import 'listview_click_listener_task-15.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
        primarySwatch: Colors.blue,
      ),
      //home: MyHomePage(title: 'Flutter Demo Home Page'),
      home: ListViewClickListener(),
    );
  }
}

listview_click_listener_task-15.dart

import 'package:flutter/material.dart';

class ListViewClickListener extends StatefulWidget {
  _ListViewClickListenerState createState() => _ListViewClickListenerState();
}

class _ListViewClickListenerState extends State<ListViewClickListener> {
  GlobalKey<ScaffoldState> _scaffoldKey = GlobalKey<ScaffoldState>();

  final List<String> _listViewData = [
    "Inducesmile.com",
    "Flutter Dev",
    "Android Dev",
    "iOS Dev!",
    "React Native Dev!",
    "React Dev!",
    "express Dev!",
    "Laravel Dev!",

  ];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      key: _scaffoldKey,
      appBar: AppBar(
        title: Text('Click Listener ListView Example'),
      ),
      body: ListView(
        padding: EdgeInsets.all(10.0),
        children: _listViewData
            .map((data) => ListTile(
                  leading: Icon(Icons.person),
                  title: Text(data),
                  onTap: () => _scaffoldKey.currentState.showSnackBar(SnackBar(
                        content: Text("$data Clicked!"),
                        duration: Duration(seconds: 1),
                      )),
                ))
            .toList(),
      ),
    );
