**What is Flutter?**
Google developed the open-source Flutter framework for building mobile apps. With only one codebase, it enables developers to create fast, cross-platform mobile apps for iOS, Android, and the web. Flutter builds UI components using a reactive programming model and a widget-based architecture, enabling quick development cycles, adaptable and lovely user interfaces, and fluid animations.


**What is flutter used for?**

Flutter has come to solve front-end developers' problems. With Flutter, you don’t need to worry about learning Android, iOS, and web development separately. With a single codebase, your app can run on them both.

Creation of Mobile Apps: Flutter is frequently used to create mobile apps with a single codebase for both Android and iOS devices. With the use of Flutter, developers can quickly produce stunning, high-performing mobile applications.

Creation of Web Apps: Flutter enables programmers to create Web Apps using the same codebase as their Mobile Apps ensuring a smooth experience on all Platforms.


Developing apps for Windows, macOS, and Linux is also supported by Flutter.

Developing Cross-Platform applications: Using Flutter, you can create cross-platform apps that enable developers to create a single code base that can be used across a variety of platforms, cutting down on development costs and time.

Best way to create an MVP: Because of its quick development cycle and user-friendliness, Flutter is a great candidate for creating Minimum Viable Products (MVPs).

**What programming language does flutter use?**

The Dart programming language is used to create Flutter apps, which take advantage of many of its more sophisticated features.

Flutter runs in the Dart VM, which has a just-in-time execution engine while developing and debugging an application. This permits quick compilation times and "hot reloading," which lets changes to source files be injected into an application that is already executing. Flutter takes this a step further by supporting stateful hot reloading, in which most source code changes are instantaneously reflected in the running app without the need for a restart or any state loss.

Release versions of Flutter apps use ahead-of-time (AOT) compilation for greater performance, except for the Web, where code is translated to JavaScript.

Dart's Pub package management and software repository, enables users to publish and use customized packages and plugins particular to Flutter.

**How to install Flutter**

Flutter has good and easy-to-read documentation that would show you step-by-step how to get it running on your system. https://docs.flutter.dev/get-started/install.I would not go deep into how you can install Flutter; you can read my next article on how to do this.


**Common Questions Asked** 

**Is flutter for the front end or the back end?**

**Answer**:  Flutter is primarily a front-end framework for building mobile and web applications. For iOS, Android, web, and desktop platforms, it offers a rich collection of pre-built UI widgets, tools, and libraries that enable developers to produce stunning, responsive, and effective apps.

Flutter does, however, have certain capabilities for interacting with backend services. It has built-in classes like http and dio that it can use to manage responses when making http queries to RESTful APIs. Flutter also enables WebSocket protocols for communication with backend services.

Having said that, Flutter is not a full-fledged backend framework, even if it does offer some capabilities for interacting with backend services. Developers generally use other technologies like Node.js, and Django to build more complicated backend systems.


**Is Flutter open source?**
**Answer**: Flutter is an open-source project that enables you to use it for nothing while also making changes to the program.



**Pros and Cons of flutter**

**Pros**

Flutter is quick since it doesn't require a JavaScript bridge because it uses the Dart programming language that has been turned into native code. Apps made as a result are quick and responsive.

Flutter is used to create cross-platform applications. it is possible to create apps for both iOS and Android smartphones using the same code from a single codebase.

Flutter is  free and open source

As a Google product, it benefits greatly from the company's enormous support and ongoing improvement efforts.

It provides easy debugging and Automated testing.

Applications made using Flutter can be created with many aspect ratios and screen sizes. Because of this, making apps that look beautiful on both phones and tablets is simple.

**Cons**

Despite having a wide variety of widgets, Flutter still lacks third-party libraries. When utilizing Flutter, one must keep in mind that flutter lacks libraries necessary for adding features and functionality to apps.

Compared to more established languages like Java, Dart is a young language. This suggests that there might be a small pool of developers who are knowledgeable about and good at using it.

Flutter apps are typically bigger than those created using other frameworks because they come with built-in widgets.

In conclusion,
     If you’re looking to make a career in app development, Flutter is the go-to language, and its space is still young and growing. 
Start by going through the documentation, buying an Udemy course, or scrabble through Youtube.
