Pros And Cons Of Flutter App Development

If you are a pro mobile app developer, then – once or frequently – you must have decided to build apps for either iOS or Android devices. But as far as beginners are concerned, they find it difficult to consider the relevant platform for this purpose, but the decision determines which technologies you need to learn to become a mobile or cross-platform app developer.


Well, wherever your app development journey drags you, Flutter is an awesome choice. Are you wondering why it is so? 


This guide will introduce Flutter app development considering its pros and cons, so it is the right time to crack what you can perform with this development kit. 

What Can You Build With Flutter?

You can build the following apps using Flutter 2.0:

  • Cross-platform mobile apps for iOS and Android;
  • Web apps – single-page apps (SPAs), Progressive Web Apps (PWAs), and the expansion of existing Flutter mobile apps to the web;
  • Desktop (Mac, Linux, and Windows) in the beta version

Widgets: The Building Blocks Of Flutter

If you are discussing Flutter, mentioning widgets is also very important. Widgets are the main building blocks of any Flutter app and describe a user interface. 

By taking the edge of the customizable widgets, you can build your UIs in Flutter. Widgets provide various properties such as heights, background, etc.

In Flutter App Development, you will find two different types:


The stateless widgets are immutable because their properties, such as height and background, cannot change once you have created a widget.

Stateful widgets

These widgets are mutable – you can utilize stateful widgets to save responses to user interactions.

Pros And Cons Of Using Flutter

It is time to break down the pros and cons of using Flutter for the cross-platform app:


Here are some most significant reasons that elaborate on why Flutter is gaining popularity over other cross-platform frameworks such as Xamarin, React Native, and NativeScript.

One Codebase to Run Anywhere

Flutter’s biggest draw is the concept of writing once, but not every time. Hence, you don’t need to be upset about maintaining consistency across the web, Android, and iOS – you can use a single codebase that will handle everything that will save resources, lead to faster build time, and simplify code maintenance.

Stateful Hot Reload

When changes are done to the code, the Flutter offers an instant UI update. Thanks to the just-in-time compiler that has made this feature possible. 

Community Support

In terms of GitHub stars, Flutter has surpassed React Native; therefore, more developers are choosing Flutter over React Native, and more developers are interested to learn more about Flutter.


By the use of Flutter, you can access the original codebase that is used to develop it. Thanks to the open resource community that has made various advances in software development over time.

Customizable widgets

Flutters offer a comprehensive line of customizable widgets: the layout, colors, text, buttons, etc., are essentially a widget.

Offer Exposure to the Dart

Dart is a language used to develop apps on any platform; the framework of Flutter is built-in Dart. So if you are willing to work with Flutter, you are supposed to learn Dart. 

Dart is a terse, object-oriented, and strongly typed programming language that delivers sound null safety. Null safety means that the value will not be nulled unless you provide the instructions. The Dart language supports the compilation of ahead-of-time (AOT) and just-in-time (JIT).

Support for web and desktop

Flutter 2.0 has stable support for the web and beta for desktop. The web support feature of Flutter is a big win because it expands your reach of end-users. With the support of a single codebase, Flutter can amazingly build apps for mobiles and the web.

Compiles to native arm code

Unlike other cross-platform frameworks, Flutter uses ARM machine code for compiling, and this machine code is a great contribution to Flutter’s exceptional performance. 

Flutter DevTools

Flutter DevTools helps you develop your apps and debug them more efficiently. With the facility of the widget inspector, you can easily navigate between device pixels, the widget tree, and the line of code.


As compared to the pros, Flutter’s cross-platform app development doesn’t include so many cons. But when you are eager to pick one platform, it is worth considering discussing the limitations and drawbacks associated with this framework.

Below are some drawbacks that you need to consider before picking up Flutter as an app development community.

Emerging framework

Though the Flutter app secures great steam among the cross-platform developer community; still, it is an emerging framework because it includes small packages, plugins, and learning resources.

The dearth of plugins/packages

When Flutter is compared to React Native, it features fewer plugins and packages comparatively. The Flutter community is introducing more plugins with every new update, so the impact of this limitation is reducing with time.

A limited number of developers using Dart

As compared to JavaScript, Flutter includes a small community of developers writing in Dart, which is Flutter’s programming. This means there are a small number of resources to help you learn Dart.


The Flutter team’s mission is to offer advanced features to the developers and shift towards what developers want to experience in app building frameworks. With time, Flutter has exceptionally evolved into a portable framework so you can work for web, Android, iOS, and desktop (Windows, Mac, Linux) for the beta.

Flutters’ benefits outweigh its disadvantages, so this platform gives you the leverage you need to create beautiful experiences and allows you to develop beautiful UIs for all devices.
