Flutter is a cross-platform app development technology, released by Google in 2018. It’s a framework used to develop both Android and iOS applications with just one codebase.
The interest in Flutter is constantly growing, as this framework combines the cross-platform flexibility and the quality of native apps.
We believe that Flutter app development is the future of mobile.
import 'package:flutter/material.dart';
void main() async {
final numbers = FibonacciNumbers();
runApp(
MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
appBar: AppBar(
title: Text('Fibonacci List'),
),
body: FibonacciListView(numbers),
),
),
);
}
class FibonacciNumbers {
final cache = {0: BigInt.from(1), 1: BigInt.from(1)};
BigInt get(int i) {
if (!cache.containsKey(i)) {
cache[i] = get(i - 1) + get(i - 2);
}
return cache[i];
}
}
class FibonacciListView extends StatelessWidget {
final FibonacciNumbers numbers;
FibonacciListView(this.numbers);
@override
Widget build(BuildContext context) {
return ListView.builder(
itemBuilder: (context, i) {
return ListTile(
title: Text('${numbers.get(i)}'),
onTap: () {
final snack = SnackBar(
content: Text('${numbers.get(i)} is '
'#$i in the Fibonacci sequence!'),
);
Scaffold.of(context).showSnackBar(snack);
},
);
},
);
}
}
As a cross-platform framework, Flutter allows you to build iOS, Android, web, and desktop apps using the same codebase. This essentially means that developers write the code just once and they can apply it to all the platforms mentioned above.
Having a single codebase cuts down the total development time, but that’s not the only thing that makes Flutter a more productive choice. The hot reload feature is one of the biggest advantages of this framework. Thanks to this solution, the developers can review the changes instantly.
Another thing that makes Flutter more efficient is the choice of customizable widgets. These speed up the work of the app developers, as they can take advantage of ready-to-implement solutions. In other words, widgets save you a lot of repetitive work. This way, you can focus on the essential features of the app.
Even when compared to native apps, Flutter’s performance turns out to be impressive. It aims to provide 60 fps performance, and even 120 fps if possible. In terms of user experience, Flutter apps are usually indistinguishable from native ones. What’s more, in some performance tests Flutter proves to be even faster than native solutions!
Last but not least, Flutter development makes it easier to maintain visual consistency across platforms. It has its own cross-platform rendering engine, which doesn’t need any bridge that would slow down the performance, like in the case of React Native.
Yes, of course it is! Flutter is one of the frameworks that make mobile development more efficient. It’s a viable choice for both iOS and Android apps.
As you might have guessed, Flutter is used in many Google products, such as Google Ads and Google Assistant. Other companies working with Flutter include Ebay, Groupon, and the Alibaba Group.
Flutter uses Dart, an object-oriented programming language, which was also created by Google.
We think so! There are many reasons for that, one of them being the use of Dart. Contrary to JavaScript (used in React Native), Dart is fully object-oriented and more type-safe than JavaScript. What’s more, it’s also usually more efficient.
Xamarin has been around for much longer than Flutter. It uses the C# programming language, which makes the transition smoother for developers who are already familiar with it. Flutter, however, is more efficient when it comes to installation, architecture, and testing. If you’re focused on productivity, Flutter will make a better choice.
Consider Flutter development if: Your time and/or budget are limited You’re tired of the complex (and costly) maintenance of native mobile apps You already have a project built on React Native, Xamarin, or Cordova, but you’re looking for an alternative You need a framework to handle advanced UI solutions
Cross-platform frameworks, including Flutter, have plenty of advantages. However, it is important to note that native applications are usually more flexible and easier to scale. On the other hand, if you’re focused on any of the things we’ve listed in the previous question, Flutter will make a better choice for you.
As you’re only working with a single codebase, building Flutter apps takes much less time than creating separate native solutions. According to Hackernoon, it takes 250 hours on average to develop a Flutter app. According to our experience, it largely depends on the projects, but it’s surely faster than native!
