Qué es Flutter y cómo trabajar con él
En este tutorial, veamos qué es Flutter y cómo trabajar con él. Aprende a crear aplicaciones móviles con Flutter. Flutter es un marco de desarrollo de aplicaciones móviles de Google que le permite crear aplicaciones iOS y Android atractivas y de alto rendimiento.
En este artículo, veamos qué es Flutter y cómo trabajar con él.
¿Qué es Flutter?
Flutter es un marco de desarrollo de aplicaciones móviles de código abierto creado por Google. Le ayuda a crear aplicaciones hermosas, rápidas y de alta calidad para iOS, Android y la web, todo desde una única base de código.
Flutter se ha convertido rápidamente en una opción popular entre los desarrolladores. Gracias a su facilidad de uso y rendimiento, puede crear hermosas aplicaciones móviles con Flutter.
Beneficios de Flutter
Flutter utiliza el lenguaje de programación Dart de Google . Dart es similar a JavaScript o TypeScript y ofrece un modelo de programación reactivo para crear interfaces de usuario.
Esto significa que en lugar de tener que actualizar la interfaz de usuario cuando cambia su código, el marco lo hará por usted. Esto hace que sea más fácil y eficiente crear interfaces de usuario dinámicas y receptivas.

Flutter también tiene un ciclo de desarrollo rápido. Flutter tiene una función de recarga en caliente que lo ayuda a ver los cambios que realiza en el código de inmediato. Con Flutter, no tienes que esperar a que el código se compile cada vez que cambias una parte del código.
La fuerza principal de Flutter son los widgets.
Widgets de aleteo
While building an app, you usually have to write functionality from scratch. For example, if you want to embed a Google map within your code, you have to write the code to import Google Maps into your app.
But Flutter provides ready-made widgets for almost all common app functions. Think of it like working with a lego set. Flutter provides a rich set of pre-designed widgets that you can customize to create beautiful interfaces.
These widgets are not simple UI elements like buttons and text boxes. They include complex widgets like scrolling lists, navigations, sliders, and many others. These widgets help save you time and let you focus on the business logic of your application.
Here is a full list of in-built Flutter widgets that you can peruse.
Another advantage of Flutter is its performance.
El motor gráfico de Flutter, Skia, dibuja cada píxel en la pantalla. Esto hace posible lograr animaciones fluidas de 60 cuadros por segundo, incluso en dispositivos de gama baja.
Flutter también tiene una comunidad grande y creciente de desarrolladores que contribuyen al marco. También viene con documentación detallada y una amplia biblioteca de paquetes y complementos. Puede integrar fácilmente esos complementos en su aplicación para agregar funciones como mapas, comunicación de red y almacenamiento local.
Ahora que sabe qué es Flutter y por qué es útil, veamos cómo se compara con otra biblioteca popular, React-Native.
Reaccionar nativo frente a Flutter
Flutter vs reaccionar nativo
React Native y Flutter son dos de los marcos de desarrollo de aplicaciones móviles multiplataforma más populares disponibles en la actualidad. Ambos ofrecen la capacidad de crear aplicaciones móviles visualmente atractivas y de alto rendimiento para múltiples plataformas.
Pero hay algunas diferencias clave entre los dos marcos que debe tener en cuenta al elegir el adecuado para su proyecto.
React Native está basado en JavaScript y es una extensión de la biblioteca React . React-native usa componentes nativos para construir la interfaz de usuario, lo que proporciona una apariencia nativa para la aplicación.
React Native tiene una comunidad grande y establecida en comparación con Flutter y es una excelente opción si sus productos existentes usan JavaScript o React.
Flutter ofrece un enfoque único para crear interfaces de usuario mediante el uso de su propio conjunto de widgets personalizables. Este enfoque le da a Flutter una apariencia única en comparación con otros marcos de desarrollo móvil.
El ciclo de desarrollo rápido de Flutter y la función de recarga en caliente permiten a los desarrolladores crear aplicaciones más rápido que otras alternativas.
React Native tiene una curva de aprendizaje más fácil en comparación con Flutter. Dado que la mayoría de los desarrolladores conocen JavaScript, no tienen que aprender un nuevo lenguaje como Dart para crear aplicaciones con Flutter.
Pero la dependencia de React Native en componentes nativos dificulta lograr un rendimiento constante en múltiples plataformas. También puede generar inconsistencias en la interfaz de usuario entre iOS y Android.
Flutter ofrece un mejor rendimiento, con su motor gráfico dibujando cada píxel en la pantalla. Con Flutter, puede obtener animaciones suaves y fluidas incluso en hardware de gama baja. Flutter también ofrece una apariencia unificada y consistente para la aplicación en todas las plataformas, ya que los desarrolladores usan el mismo conjunto de widgets para crear la interfaz de usuario.
Entonces, React Native y Flutter tienen sus propias fortalezas y debilidades, y la elección correcta depende de sus necesidades y requisitos específicos.
React Native es una buena opción para empresas con inversiones existentes en JavaScript y React. Flutter es una mejor opción para proyectos que necesitan interfaces de usuario receptivas, únicas y de alto rendimiento junto con un ciclo de desarrollo rápido.
Cómo instalar Flutter
The best way to install Flutter is to follow the official installation page. You can choose your operating system and follow the instructions.
Once you have installed Flutter, you can use its inbuilt tool called Flutter doctor to check the components. For example, on Mac, you should see a similar response on running flutter doctor .
Flutter doctor
Hello World in Flutter
Let’s create a simple hello world app using Flutter.
We can use the flutter create <app name> to create a new app.
Flutter create
Now we can cd into the directory and change the main file. It will be located under <app_name>/lib/main.dart. Replace the code in the main.dart file with the following code.import 'package:flutter/material.dart':
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Hello, World!',
home: Scaffold(
appBar: AppBar(
title: const Text('Hello, World!'),
),
body: const Center(
child: Text('Hello, World!'),
),
),
);
}
}Este código define una aplicación de Flutter que mostrará "¡Hola, mundo!" en el centro de la pantalla. La función main() llamará a la función runApp() con una instancia de la clase MyApp.
En el método build() de MyApp, un widget de MaterialApp con el título "¡Hola, mundo!" es creado. El widget Scaffold contiene una barra de aplicaciones con el título "¡Hola, mundo!" y el widget Center colocará el texto en el centro de la pantalla.
Así es como se verá la salida después de ejecutar el flutter runcomando.
Flutter hola mundo
¿Qué es Flutterflow?

Antes de terminar, quiero compartir una herramienta que ha mejorado enormemente mi productividad al crear aplicaciones con Flutter. Esto no es un respaldo, simplemente me gusta mucho la herramienta y quiero que usted también sepa sobre ella.
Flutter Flow es una herramienta de diseño visual que te permite crear aplicaciones de Flutter mediante una interfaz de arrastrar y soltar. Puede crear interfaces de usuario complejas e interactivas para sus aplicaciones Flutter sin escribir ningún código.
Flutterflow funciona proporcionando una interfaz visual para diseñar la interfaz de usuario de su aplicación, que luego se traduce al código de Flutter. Facilita la creación y la iteración del diseño de su aplicación, ya que puede ver los cambios que realiza en tiempo real.
Flutterflow también ofrece desarrollo colaborativo, por lo que puede crear sus aplicaciones junto con un equipo. Flutterflow viene con muchas integraciones como Firebase, Stripe e incluso la API de OpenAI.
Una vez que haya creado su aplicación, puede publicarla en la tienda de aplicaciones o en la tienda de juegos utilizando la integración integrada de Codemagic.
Conclusión
Flutter es un marco increíble para crear aplicaciones móviles. Ofrece tiempos de desarrollo rápidos, diseños hermosos y receptivos, y una base de código única para iOS y Android. Su función de recarga en caliente permite a los desarrolladores ver los cambios en tiempo real, lo que reduce el tiempo total de desarrollo.
Además, la biblioteca de widgets de Flutter permite la creación de diseños personalizados y complejos con facilidad. En términos de rendimiento, Flutters va muy por delante de alternativas como React-Native.

Google's Flutter 1.20 stable announced with new features - Navoki
Flutter Google cross-platform UI framework has released a new version 1.20 stable.
Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.
Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store. If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.
Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.
Here are the few key points of this release:
Performance improvements for Flutter and Dart
In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.
If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.
Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.
Autofill for mobile text fields
Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.
A new widget for interaction
InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.
Updated Material Slider, RangeSlider, TimePicker, and DatePicker
In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSlider, DatePicker with support for date range and time picker with the new style.
New pubspec.yaml format
Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.
Preview of embedded Dart DevTools in Visual Studio Code
Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.
Network tracking
The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.
Generate type-safe platform channels for platform interop
Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.
There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

What is Flutter and why you should learn it?
Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).
Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.
There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.
Flutter meaning?
What is Flutter? this question comes to many new developer’s mind.
Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.
So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.
Where Flutter is used?
Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are
Dream11
NuBank
Reflectly app
Abbey Road Studios
and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.
