I want to implement rows after named section, something like in Android phone contacts:
I mean a section name (for example * Favorites
) and one or more rows after this name (TechBone net
). Could anyone say what widget(s) should be used in Flutter for such task?
CodePudding user response:
You can use MixedList by customising this example (provided by Flutter Official Documentation)
import 'package:flutter/material.dart';
void main() {
runApp(
MyApp(
items: List<ListItem>.generate(
1000,
(i) => i % 6 == 0
? HeadingItem('Alphabet $i')
: MessageItem('Contact $i', 'Number $i'),
),
),
);
}
class MyApp extends StatelessWidget {
final List<ListItem> items;
const MyApp({super.key, required this.items});
@override
Widget build(BuildContext context) {
const title = 'Mixed List';
return MaterialApp(
title: title,
home: Scaffold(
appBar: AppBar(
title: const Text(title),
),
body: ListView.builder(
// Let the ListView know how many items it needs to build.
itemCount: items.length,
// Provide a builder function. This is where the magic happens.
// Convert each item into a widget based on the type of item it is.
itemBuilder: (context, index) {
final item = items[index];
return ListTile(
title: item.buildTitle(context),
subtitle: item.buildSubtitle(context),
);
},
),
),
);
}
}
/// The base class for the different types of items the list can contain.
abstract class ListItem {
/// The title line to show in a list item.
Widget buildTitle(BuildContext context);
/// The subtitle line, if any, to show in a list item.
Widget buildSubtitle(BuildContext context);
}
/// A ListItem that contains data to display a heading.
class HeadingItem implements ListItem {
final String heading;
HeadingItem(this.heading);
@override
Widget buildTitle(BuildContext context) {
return Text(
heading,
style: Theme.of(context).textTheme.headline6,
);
}
@override
Widget buildSubtitle(BuildContext context) => const SizedBox.shrink();
}
/// A ListItem that contains data to display a message.
class MessageItem implements ListItem {
final String sender;
final String body;
MessageItem(this.sender, this.body);
@override
Widget buildTitle(BuildContext context) => Text(sender);
@override
Widget buildSubtitle(BuildContext context) => Text(body);
}
