Your full guide to Flutter & why you should learn it in 2022

Flutter is the most recent framework to create a name for itself in the field of mobile app development. 

Google announced Flutter, a free and open-source mobile UI framework, in May 2017. In a nutshell, it enables you to develop a native mobile application using only one codebase. This means that you can construct two distinct apps using a single programming language and codebase, both for iOS and Android.

Dart is a programming language that is used to create Flutter applications. Google developed the language in October 2011, although it has evolved significantly over the years. Dart is a front-end development language that may be used to construct mobile and online apps. It is a typed object programming language for those who are familiar with programming. Dart syntax is similar to JavaScript syntax.

Further, Flutter is made up of two major components:

1. A Software Development Kit or SDK is a collection of tools that will assist you in developing your apps. Tools for compiling your code into native machine code are included (code for iOS and Android).

2. A framework or a widget-based UI library: A set of reusable UI components that you may get customized to meet your specific needs.

You may master all these and more with a good full stack web development course if you are into programming.

Flutter does not even use OEM widgets and instead provides its own ready-made widgets that seem natural in either Android or iOS apps. It is also possible to make your own widgets.

Notably, Flutter is the only framework with a mobile SDK that delivers a responsive style without the use of a JavaScript bridge, achieving performance levels comparable to its cousin and direct competitor React Native. It interacts effortlessly with several platforms such as Android, iOS, and Linux, as well as MAC, Windows, and Google Fuchsia apps.

Why is it Used?

Flutter is a technology that is built on widgets. This means that object-oriented programming may be applied to any element. 

One advantage of adopting Flutter is the simplicity with which you can edit or customize widgets. It also includes UI widgets that suit important web application design standards.

Since its inception as an open-source framework, Flutter has garnered a large and active development community. This community is continually publishing useful code samples and assisting developers in creating fresh, inventive, and visually appealing cross-platform programs.

‍Flutter is one of the greatest ways to create apps for both Android and iOS without having to construct a separate codebase for each platform. The smartphone versions of these applications work as full native apps on Apple and Android devices and are built for each platform prior to publishing.

They do not require a browser or a runtime module. It is also feasible to construct web apps for browsers as well as native programs for Windows, Linux, and macOS using the same codebase.

Flutter is used by Google for numerous modules of Google Assistant as well as the user interface of the Google Home hub. Take up a full stack web development course to gain more insights into this field! 

What makes Flutter a good framework for mobile app development?

1. Hot reloading

Hot reload allows you to see changes in the code immediately reflected on the UI. This expedites the process of working on the application’s appearance. Also, it allows developers to repair faults, saving money and time.

2. Development that is simplified and agile

The first thing to highlight in Flutter is the developer’s agility. It is considerably easier to construct interactive features while creating software when a widget system is provided for development.

As a result, the final product may be more agile and have better quality on Android and iOS versions, as intended. Furthermore, the ‘hot reload’ feature makes it simple to see the changes made to the code, offering fast feedback to the developer and therefore, enhancing productivity.

3. Developmental single language

Flutter relies only on the Dart programming language to create its applications. As a result, it significantly simplifies the job of developers, who simply need to know Dart to perform their responsibilities. 

Google launched the language in 2011 and its code features are extremely comparable to C# and Java. In other words, for developers accustomed to the aforesaid languages, the transition to Dart is not difficult.

4. Widget repository

In Flutter, everything is specified as a widget. A widget may be anything from a color to padding to a menu. Flutter can create sophisticated widgets that can be adjusted to meet the needs of the application. 

There are also built-in widgets accessible for use. Cupertino pack and material design are two examples of widget sets that deliver a smooth user experience.

5. Open-source

Flutter was introduced by Google as an open-source platform. Developers may experiment with several design possibilities while creating Flutter apps. Material design and Cupertino widgets may be used to develop user-friendly applications. 

Flutter Form is a community of Flutter aficionados who get together to answer and debate Flutter-related queries. Flutter is completely free with extensive documentation and online forums.

Flutter Advantages: Why is it Better?

1. Flutter allows you to create an Android, iOS, or web app with a single codebase. Of fact, all cross-platform frameworks are meant to achieve this, but Flutter makes the process quite simple and the results incredibly attractive.

Creating prototypes is easier than ever using Flutter’s custom widgets. Flutter adds to Google’s Ambient Computing concept, which sees Flutter-created apps are available anywhere you need them to be, independent of hardware constraints.

2. In today’s highly competitive digital marketplace, coming to market sooner might be the one thing that separates you from the competition.

When you use Flutter, you can create your application faster than with a traditional native application. Not only does creating a single codebase that works on various platforms save time, but Flutter also includes a variety of other characteristics that help you save time all through the development cycle.

3. Another factor for Flutter’s quick adoption among developers (apart from its great productivity) was the availability of extensive documentation and a huge number of examples. This is especially critical for developers learning a new platform, set of tools, or language.

4. Flutter can code on low-powered PCs and is simple to start up. Furthermore, it never requires powerful devices to function.

Flutter Disadvantages: It’s Limitations

1. The only drawback is that Flutter apps are larger in size. Flutter applications are often larger than 4MB.

2. We already know Flutter is a Google product. Apps made using Flutter are entertaining on Android but have certain issues on iOS.

3. Besides, Flutter does not support third-party libraries, which complicates the programming effort. However, if an app is well planned, Flutter has the potential to be the greatest.

4. Flutter is a new cross-platform application development framework. Many Flutter functionalities are in alpha and beta testing phases and may not always perform correctly. 

Moreover, some functions are not available in the present library because the platform is still being completed. It will take some time for Flutter to develop the required tools, improve functionality, and grow the community.

5. Because Flutter is a Google product, the quality of support for iOS applications suffers. If the majority of the SDK functionalities on Android operate well, there are issues with iOS. 

When using an Apple device for photography, for example, the program deletes all EXIF data. As a result, the photo is presented with improper orientation, no location, no date, and no accurate gamma. Special iOS features (VoiceOver, Guided Access, Captioning, and Audio Description) are essentially non-existent nowadays.

Flutter vs Other Mobile App Development Frameworks

Flutter vs PWA

Progressive Web Apps (PWA)-created apps are cross-browser interoperable. They function with limited internet access and offline. PWA automatically updates itself, keeping the apps up to date. However, because the applications are supplied through HTTPS, unauthorized users cannot access the content.

Installation is more difficult than with Flutter-based apps. Users must travel to the website to install and start the app, which limits the user experience. 

PWA apps are compatible with iOS and Android, however, they lack the native experience that Flutter provides owing to a lack of native mobile libraries. If the goal is to create a better user experience, then Flutter is a preferable alternative for the discriminating mobile app developer.

Flutter vs React Native

React Native is regarded as one of Flutter’s main competitors. React Native, like Flutter, is an open-source, cross-platform app development platform. 

Both are cost-effective and time-saving solutions since they include the hot reload functionality for on-the-fly innovation. 

Flutter has a plethora of widgets that allow developers to create visually appealing apps. It has an active community and extensive documentation, allowing even inexperienced developers to get started. 

Unlike Flutter’s widgets, React Native employs bridge and native elements, necessitating distinct optimization for each platform. This has an effect on their time to market. This might be discouraging for developers in a fast-paced setting where breakthroughs come on a regular basis.

Why Choose Flutter?

While there are several reasons why you should choose flutter over its alternatives, one of the most important reasons is that it allows you to develop apps faster and cheaper than competing frameworks. Because it is all part of an SDK, developers may add features such as push notifications, ad networks, and deep linking.

So, why is Flutter better? Flutter employs a reactive programming style, which simplifies the development of apps that function smoothly and reliably across platforms. Also, because Flutter utilizes a single language for everything, it is simple to transition from an MVP to a full-featured production project without having to rebuild the codebase.

Use Cases of Flutter

1. Reflectly 

Reflectly is an example of an app that was first built in React Native. Using this technique, the team developed it for iOS. 

When they decided to launch the Android app, an issue arose. Because of the app’s huge success, they decided to completely redesign it in 2018. They selected Flutter because it was ideal for this purpose.

2. Philips Hue 

Philips Hue is a smart lighting solution for the home. Customers that desire intelligent lighting in their homes can get lamps, bulbs, accessories, and starting kits from them. 

Hue Sync and Hue Bluetooth are two of their apps made with Flutter. Clients of Philips may use these mobile controllers to alter the color of their lights and coordinate them with their media kits.

Philips has been using Flutter since 2018. It chose this technology over other excellent options in the market. Philips just resonated with Flutter and felt it was the right fit for its project.

3. New York Times 

At the same time, New York Times made its KENKEN game accessible. It is no surprise that it was created utilizing Flutter.

Flutter is a promising framework that is suitable for both small- and medium-sized apps. With Flutter’s help, NAPP BaaS has entirely transformed. The fundamental concept behind this software is that it has the ability to alleviate numerous problems that every property owner has with visitor procedure management.

When talking about Flutter, everything is a widget. This allows everyone to develop their own custom widgets or expand existing widgets and screen views via code, making it incredibly simple to adopt Flutter. 

Learning languages like Java and C++ is essential. Before you can learn Flutter, you must master Dart programming. Notably, Dart is the general-purpose programming language used by Google.

Flutter’s popularity is skyrocketing. It solves challenges encountered by companies, particularly when dealing with limited time and resources to bring a product to market. Flutter is ideal for developing a personalized application experience.
