Flutter App Development: Your Programming Encyclopedia Of Pros & Cons

Unknowingly, you have already come across apps preferably built on Flutter. While shopping on Alibaba, making transactions through Google Pay, or running campaigns through Google Ads, you have witnessed the charms and depravities of Flutter.

Flutter App Development process ingrained its name in the encyclopedia of computer programming immediately after its mega launch in 2017. It didn’t take long for Flutter to gain traction after the release of its official stable version in December 2018. 42% of software developers continue to use Flutter, making it the most majestic front-end framework.

Bird’s Eyeview of Flutter Architectural Layers

Reading dry content of Flutter books while pushing glasses up your nose bridge to have your query “Is Flutter a programming language?” addressed can be a major blocker in your Flutter app development project. 

Pushing you one step towards the planning phase of Flutter app development, InvoZone assures you that it is not a programming language. It is a Google-maintained framework! 

But with its hometown in Google headquarters, it didn’t stay as a mediocre framework. Instead, it immediately got upgraded to a complete software development kit (SDK). A rendering engine, an enriched set of developed widgets, unit and integration testing APIs, plugin APIs, and command-line tools constitute the Flutter SDK. It effectively builds and compiles apps. 

Let’s dig deeper and explore the basics of Flutter architecture:

The main architectural layers involved in the Flutter App Development are as follows: 

1. Embedder

This platform-specific embedder is the opening door that coordinates with the operating system to run the apps. It is written in a language such as Java and C++ for Android, Objective-C/Objective-C++ for iOS and macOS, and C++ for Windows and Linux. 

2. Engine

Claiming the spot at the core of Flutter, Google wrote an engine in C++. It actively supports all the primitives required to make Flutter apps. Not to mention, it reinforces the low-level implementation of Flutter’s core API, graphics, text layout, file, and network I/O, accessibility support, plugin architecture, a Dart runtime, and a compiled toolchain. 

3. Framework

People often ring the doorbells of Flutter app developers to search for an answer to their question: 

“Is Flutter backend or frontend framework?” 

But do not worry because you are at the right place! Our well-versed flutter developers confirm that it is an open-source front-end framework. They interact with the Flutter framework that is written in Dart programming language. It displays a rich set of platforms, layouts, and foundational libraries.

Pros of Flutter App Development

Now that we have clarified the technical architecture, let’s explore the top advantages of Flutter app development: 

Fast UI Coding Over All Platforms 

Being a cross-platform framework, Flutter developers build modern apps using a single codebase for all platforms. The underlying gem that enables fast UI coding is Flutter widgets. 

Any item, from a button to padding or a typeface, is a widget. You can utilize them to form layouts. To emphasize, you can use them at any degree of modification, from existing building blocks to the most basic level.

Furthermore, widgets in Flutter are grouped in trees. Henceforth, it is convenient for rendering but may result in overcomplicating the overall structure. Large applications may take up to ten layers of code to build a basic object. Therefore, your development team must plan and define the structure ahead of time.

Dart Programming Language Is Winning Hearts

Dart programming language forms the founding grounds of Flutter, but it does not fail to remind you of Java and C++ through its syntax. Not only is it client-optimized but also platform-independent, which assists in developing apps on any platform with minimal hindrances.

Therefore, it rapidly found its well-deserved spot in the list of the most loved programming languages, with a promising percentage of 62.16%.

Google Guarantees Long-Term Support 

Because Google funded Flutter and Google itself is an early adopter of this technology, you can be confident that the Flutter community will provide long-term maintenance. Thus, you can resolve all errors promptly, and your product will continue to evolve with time.

Not convinced yet? Oh, you’re a tough nut to crack. Have a look at the following fact:

Google Fuchsia is another initiative that the company has been working on for years. It's a free and open-source operating system built around the Zircon kernel. And guess what! The tech giant is creating Fuchsia UI and applications with Flutter to ensure multi-platform compatibility and great performance. Given its engagement in such a large project, we anticipate Flutter app development services will not be abandoned anytime soon.

Get Instantaneous Updates Through Hot Reload Function 

Typically, iOS and Android developers create code, wait for it to compile, and then load it onto the device before making modifications. However, Flutter shows them a green light to test the results instantly or without interruptions using its hot reload.

In other words, your development team, especially in collaboration with our experienced QA engineers and designers, can work more efficiently, make rapid adjustments, and see the results. It is precisely why Flutter app development takes less time than others.

Enhanced Time-To-Market Speed 

This one is rather simple. Flutter programming framework is faster than its competitors. In most circumstances, a Flutter app development project will need at least twice as many man-hours as the identical software designed independently for Android and iOS. 

The primary reason is straightforward: you do not need to develop any platform-specific code to obtain the appropriate aesthetics in your application while working with Flutter. 

Thus, we, InvoZone Flutter developers, highly recommend augmenting your in-house team with remote developers who will bring in years of experience and advanced skill sets. In addition, you can construct any 2D-based UI without requiring an interaction with a native application equivalent by hiring Flutter app developers.

Aside from that, Flutter provides a declarative API for designing UI, which significantly improves speed in our experience. 

Cons of Flutter App Development

The world can witness colors of success in the future of Flutter app development if the community manages to neutralize the impact of its cons. InvoZone’s quick-witted developers have fine-tuned strategies and practices in place to keep the disadvantages of Flutter app development at bay! 

Absence of Third-Party Libraries

Third-party libraries and packages play a significant role in automating software development processes and eliminating the need to write code from scratch. These libraries are typically open source, freely accessible, and pre-tested - who wouldn't want to use a tool that has previously been used and reviewed in a variety of settings?

Finding the required package for various older and more common technologies is rarely a major challenge. However, it is frequently a problem for newer ones. There are already over 25k packages on Flutter's official site, and the number is rising.

Of course, it's less than its major rival, React Native, but it's more than enough. Furthermore, as previously stated, Flutter widgets enable the majority of the development cycle to be completed without the use of third-party tools.

Slow Adoption of Dart Programming Language 

Dart is an excellent language in and of itself. Its paradigm should be familiar to most programmers because it is quick and object-oriented. However, it lags behind other technologies in terms of adoption, particularly TypeScript, C#, and Java.

To put it differently, finding new talent for your mobile team might be difficult because not many beginning engineers will pick up Dart on their path. It is something to think about while deciding on a cross-platform approach.
