A basic code to get you started on creating a travel app in Flutter:
import ‘package:flutter/material.dart’;
import ‘package:http/http.dart’ as http;
import ‘dart:convert’;
class TravelApp extends StatefulWidget {
@override
_TravelAppState createState() => _TravelAppState();
}
class _TravelAppState extends State<TravelApp> {
List _destinations = [];
@override
void initState() {
super.initState();
_fetchDestinations();
}
_fetchDestinations() async {
final response = await http.get(“https://your-api-endpoint.com/destinations”);
if (response.statusCode == 200) {
setState(() {
_destinations = json.decode(response.body)[“destinations”];
});
} else {
throw Exception(“Failed to load destinations”);
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(“Travel App”),
),
body: ListView.builder(
itemCount: _destinations.length,
itemBuilder: (context, index) {
final destination = _destinations[index];
return ListTile(
leading: Image.network(destination[“image_url”]),
title: Text(destination[“name”]),
subtitle: Text(destination[“description”]),
);
},
),
);
}
}
In the code above, we use the http package to fetch a list of destinations from a remote API. The destinations are displayed using a ListView.builder, with each item in the list being represented by a ListTile widget that shows the destination’s name, description, and image. The image is loaded from a URL using the Image.network widget.
This code provides a basic starting point for a travel app, but there are many ways to improve it. For example, you may want to add the ability to filter destinations based on various criteria, such as location, price, or popularity, as well as to show detailed information about each destination, such as its location on a map, available accommodations, and nearby attractions. Additionally, you may want to consider adding support for user authentication and booking, so that users can save their favorite destinations, make travel plans, and book trips directly from the app. These are just a few examples, and there are many other features and improvements you can make to create a complete and fully-functional travel app in Flutter.
