Why Use Flutter: Pros and Cons of Flutter App Development

Why use Flutter

Flutter is one of the most dynamically evolving tools for creating cross-platform applications. If you came across this article by googling Flutter, then you’re probably wondering what all the buzz is about and whether Flutter is worth a try.

This article will help you better understand what Flutter is and why to use Flutter for app development. The information presented includes an overview of the reasons to use Flutter, while the Flutter pros and cons will explain why many engineers choose Flutter over its competition. In short, it answers the question why you should choose Flutter and what benefits you will get when working with this tool.

What is Flutter?

Flutter is an open-source UI framework developed by Google that allows developers to build native-quality mobile, web, and desktop applications from a single codebase. Flutter is a valuable modern tool used to create stunning cross-platform applications that render native code on each device and OS. Flutter is compatible with Android, iOS, Linux, macOs, Windows, etc.

There are two key components of Flutter:

Flutter Architecture overview

The Flutter tool incorporates three architectural layers:

  • Framework: The most visible part of the Flutter technology. It is based on the Dart programming language.
  • Engine: Written in C/C++, this layer provides graphics, accessibility support, text layout and other essential APIs.
  • Embedder: A platform specific embedder is used to help the Flutter App to run on any OS.

How Cross-platform Development Works with Flutter

Flutter is a multiplatform technology that maximizes code exchange and ensures interoperability with different platforms. The developer creates an original code that becomes exclusive to each platform instead of creating native solutions.

Flutter helps companies save their development budgets, as there’s no need to hire native app developers, you just need a professional Flutter engineer creating the functionality, and the tool will do the rest. It is compatible with mobile platforms (iOS and Android), Desktop platforms (Windows, Linux, MacOS), as well as the web.

As a result, the shared code approach is used to quickly develop software of any complexity and makes Flutter one of the best known tools for fast and cost-efficient MVP development.

Why Use Flutter: Pros and cons

Flutter cross-platform grow

Ever since Flutter came out, it has drawn a large and engaged community of developers. One of the benefits of Flutter is that it is simple. This means widgets can have changes or are subject to customization with ease. Moreover, the Dart programming language and Flutter are easy to learn and start creating with, so that there never will be a shortage of specialists, any software engineer can easily and quickly switch if needed. One of Flutter’s most appealing elements is UI widgets that adhere to important web application design standards.

About Widgets

Widgets are components that appear on a screen of the Flutter app. The choice and arrangement of the widgets used to create an application is important. It has a significant impact on how the screen will look like.

AccessibilityWidgets that make applications more accessible
Animation and motionsWidgets that add more animation to other widgets
Assets image and iconWidgets in charge of assets like display images and show icons
AsyncWidgets that provide async functionality in the Flutter app
BasicsWidgets that are essential for the Flutter app development
CupertinoWidgets designed for iOS apps
InputWidgets that provide input functionality in the Flutter app
Interaction ModelsWidgets that manage touch events and guide users to different views in the app
LayoutWidgets as a support system for other widgets to be placed on the screen when needed
Material ComponentsWidgets that follow material design guidelines by Google
Painting and EffectsWidgets that apply visual changes to their child widgets avoiding any layout or shape changes
ScrollingWidgets that help other widgets scroll by default
StylingWidgets in charge of the theme, size and responsiveness of the app
TextWidgets that display and style the text

A contemporary framework is used to create Flutter widgets. Essentially they serve as building blocks for your application interface. They provide descriptions of how their views should appear given their settings and current state.

Widget categorization and functionality are visible in the chart above. It shows the advantages of having widgets lead to the simplicity with which the Flutter framework can be used.

But, why Flutter? This next section will explain other reasons why you should choose Flutter over other cross-platform app development tools such as React Native, Cordova, etc. Here’s a short list of the advantages of flutter app development as well as the disadvantages you should be aware of to make Flutter work for you.

Advantages of Flutter

Advantages of Flutter
  • Single codebase for all platforms: There is no need to create separate code bases when working on iOS and Android devices. Flutter allows developers to build a single codebase and use it for several platforms such as the web, desktop and mobile. This results in quicker app launch and is cost effective.
  • Reduced Development Time: The requirements for Flutter application development are much lower. So the positive outcome is that there are no additional maintenance charges. Flutter makes it possible to create larger apps that use unique features.
  • Increased Time-to-Market Speed: The Flutter development framework is more responsive than others. This tool’s quick time-to-market is one of its key advantages. It is mostly difficult to predict if iOS or Android versions will be able to provide a product on time. This is where Flutter plays its role, as it allows cross-platform usage.
  • Native-like Performance: This is one of the Flutter advantages that stands out the most. Flutter works with Skia, a graphics engine which enables quick and well optimized development. It also is indistinguishable from native apps as it doesn’t rely on interpreters or intermediary code representations.
  • Powerful community: According to statista, Flutter has become one of the most popular frameworks and a first choice by developers globally. Over 40 percent of software developers have chosen Flutter over the course of the last three years. The following chart shows the growing interest in Flutter in comparison with other cross-platform app tools.
  • Own Rendering Engine: The problem with some cross-platform solutions is that they are very similar on iOS and Android. This is why Flutter is the best option, because it consists of packages that contain a set of unique widgets for both operating systems.
  • Hot Reload Feature: The ability to hot reload is one of the main benefits of using Flutter. This is for effective cross-platform development so it can complement the nature of Flutter. This feature’s function speeds up application development.
  • Flutter’s Safety. Null-safety is supported on the syntax level. Flutter’s UI code is single-threaded, and computational threads are executed in isolated sandboxes which means no shared or unsafe resources at all.
  • Dart: Developers’ reason to choose Flutter is because of the Dart programming language Flutter is based on. It has features that make it stand out from other languages:
    • Ahead Of Time (AOT) compiler which makes Flutter Widgets customizable and a quick startup possible.
    • Just In Time (JIT) compiler, since it makes it possible to optimize a code while it is running.

    Dart compiles into highly optimized JavaScript on web platforms. The next step is WebAssembly for Web which will provide much better execution/animation speed compared with other platforms. These are only some of the features that make Dart count as an advantage of using Flutter for development purposes.

  • Excellent documentation and community support: Flutter benefits from extensive documentation and a vibrant community. Developers can find resources, tutorials, and support easily, making it easier to learn and troubleshoot any issues they may encounter.
  • Strong industry adoption: Flutter has gained significant traction and is used by well-known companies such as Google, Alibaba, Tencent, and more. Its growing popularity ensures ongoing support and updates from both Google and the Flutter community.
  • Material Design and Cupertino widgets: Flutter provides out-of-the-box support for both Material Design (Android) and Cupertino (iOS) widget sets. This ensures that the UI looks native on both platforms, creating a consistent and familiar user experience.

Flutter Disadvantages

Disadvantages of Flutter

No tool is perfect and Flutter is no exception. Flutter itself can have a few drawbacks because it is still a new tool for certain applications. Let’s not forget that it was created only a couple years ago, so the community is still testing its limitations and identifying compatibility issues on various platforms. The fact that it is meant to work with numerous platforms leveraging their peculiarities makes it more difficult and time-consuming to make it work with everyone, but at Waverley we believe the tool will get there eventually.

  • Large and Weighty Apps: A loophole that can’t be dismissed is the size of the large size of the applications under development. Software developers working with this toolkit may find it difficult to work with large files. This can cause them to choose a lighter alternative.
  • Dart’s low popularity: It’s a fact that Dart is a reliable programming language since it is fast. It is also true that developers are starting to make it an option. Yet, Dart is still not able to compete with other top programming languages such as java, Kotlin, etc.
  • Problems with iOS: The Flutter framework works well on both Android and iOS. However, Flutter was developed by Google, which gives Android apps a key advantage. It isn’t considered a major issue, but it is something to consider in case some problems may be present in the future.
  • Limited number of third-party libraries: Flutter being relatively cannot be compared to native programming languages. Developers still need to spend more time building as many libraries as possible.

As a new toolkit it is still adapting to changes and improvements. But hopefully we now gave you a better understanding why using Flutter is a fast and cost-efficient alternative to native app development.
