Flutter vs. Angular: Which one is better for Software Development?

In our technologically advanced age, owning a Smartphone is becoming a requirement for everyone. Now anyone has got equal business opportunities. Everyone needs mobile applications that perform consistently on all devices. As a result of the quick rise in application development, several app development frameworks and languages have evolved. 

Now every business owner needs good user-friendly high-performance apps with great front-end development. 

Today many options like Angular, Flutter, Node JS, ReactJS and so many others are available for frontend development. Angular and flutter are the two most famous frontend frameworks because of their unique tools, functionalities, and native UI.

Many big companies and organization like Google, Tesla, and SpaceX developed their application with these frameworks.

In this article, you will get a clear understanding of the two most popular frameworks Angular and Flutter for frontend development. We also discuss their performances, security, cost efficiency, and basic differences so, you get a clear view of these two frameworks and choose the perfect framework according to your need.

Let’s first find out the basic information about these frameworks:

What is Flutter?

Google develop Flutter in 2017 for cross-platform app development. Flutter is currently one of the most popular app development frameworks for creating contemporary applications. It enables users to develop online, desktop, and cross-platform applications for Android, iOS, and the web. 

It is built on Dart (also developed by Google), an object-oriented programming language that is faster and easier to use than traditional approaches in front-end development.

Because of its basic architecture and advanced functionality, Flutter is quicker than others.

Some prominent apps built using flutter include the eBay Motors app, Google Ads app, Groupon, Dream11, and many others.

Pros and Cons of Flutter


Hot Reload Feature

It minimizes code development time due to its ‘hot reload’ function, which allows developers to rapidly update any modification, making it quicker. There are several ready-to-use widgets that are very customizable.

Code Base

We can create an application for any platform using the same code base. To manage, update, and debug our code, all we require is a single code base.

Easy to Use

Flutter is one of the simplest frameworks to learn and use. Any programmer who has knowledge of object-oriented programming can use flutter easily. Flutter also provides all the built-in functions and libraries and it saves the programmer from writing heavy code.

Flutter also works with almost every IDE (Integrated Development Environment) which is basically a platform for programming


Large binary size

Flutter includes widgets, and the binary footprint for a bare-bones project reaches 4 MB. Apps produced using Flutter may have bigger binary sizes than those built with other frameworks. This may be a major problem for all the programmers that flutter projects use a lot of space in memory.

But the flutter framework community works to make it more efficient and regularly released updates so this problem may be solved shortly by them.

Limited Third-Party Libraries

Third-party libraries or packages play a crucial role in automating software development as well as eliminating the need to start from scratch. Because of the framework’s youth, certain developers may find it difficult to discover third-party libraries that meet their requirements, making development more challenging.

Younger Community

Flutter has a limited community and developer pool than competing frameworks like as React-Native, Ionic, Xamarin, and others because it is a newer framework. This might make it more difficult to get assistance and services when you want them.

Using an increasing number of apps produced with Flutter, company executives and startup founders may use this framework for quick app development and outcomes. Some apps developed using Flutter are much more famous than others. Let’s have a look at some of these applications that build on this framework.

  • SpaceX Go – The SpaceX Go application is developed using Flutter. SpaceX is an Elon Musk Space research company. SpaceX Go provides details about SpaceX’s upcoming plans and rocket launch dates. This also gives details about various capsules, rockets, and ships created by SpaceX.
  • Google Ads – Google Ads application is built using Flutter which is essential for business owners and organizations who want to manage their online ads. Google Ads help them to create and maintain ads without hard work. This app provides the features like managing ads, impressions, online alerts, and Google support. 

What is Angular?

Angular is a TypeScript-based open-source JavaScript framework. It is maintained by Google, and its primary function is to produce single-page apps. Angular offers significant advantages as just a framework, while also offering the standard structure that developers work with. It helps users to create big applications and maintainable them.

Angular provides lots of features for security purposes, stability for huge, and a function-rich library for app development. The main purpose of the angular framework is to provide a high-performance UI for large applications which take a lot of loads or are used by many users at the same time.

Pros and Cons of Angular



Angular is based mainly based on JavaScript and TypeScript. It provides functionality like routing, data transport between client-server and forms management which makes it a great tool for scalable and secure websites. Also, development in Angular is efficient and easy for developers.  

Data binding

Angular allows users to easily transfer data across JavaScript code to the screen and respond to user interactions without writing any code. This provides a class and method to observe all the changes in data and this gives freedom to the programmer to change the UI without any worry.

Custom components

Angular allows users to create their own components that may combine functionality and drawing logic into reusable sections. It is also compatible with web components. Also, this gives a lot of pre-written codes so you can use them directly.

Browser Compatibility

Angular is cross-platform and works with a variety of browsers. Angular apps may be executed on any browser (Chrome, Mozilla, etc.) and OS (Windows, macOS, and Linux). This means the apps developed using Angular can work seamlessly on any OS or browser.

Cons of Angular

Learning Angular

For new developers who are already familiar with JavaScript, learning Angular is a little tough. It is because JavaScript provides a wide range of subjects and elements for the developer whereas angular is focused mainly on web application development. 

CLI documentation is lacking details

Numerous developers have expressed their dissatisfaction with the present status of CLI documentation. While the command line is extremely beneficial for Angular developers, there isn’t enough information in their official documentation on GitHub, and you’ll have to spend more time reading GitHub discussions to understand.

Not Useful for all Projects

While using angular you should be aware of your project like its size, complexity, and features you want to include. Angular provides a lot of hidden features and functionality so you have to know about the requirements, size, and complexity of your project to make it successful. 


PayPal facilitates the movement of millions and billions of dollars every day. Whether you are a person or a corporation, PayPal allows you to send money quickly and easily. 

At the moment, there are around 300 million active users or more programmer that utilizes PayPal for online money transactions. PayPal also provides real-time transaction data streams.


One of the world’s most popular websites builds on Angular. It is designed using Angular 5 and responds to over 74 million monthly queries in the United States. 

It covers a wide range of topics and shows how digital editions may become almost as legendary as the magazine’s debut issue, which was released more than a century ago.


Gmail is the most suitable example to know the capabilities of Angular. Gmail has around 1.5 billion users across the world.

Gmail provides us with real-time high performance with a simple UI. Everyone has experience with Gmail features, performance, and Scalability. 

Key Differences Between Flutter and Angular

Programming Language

In Flutter vs Angular, Flutter uses Dart programming language created by Google. inc, while Angular is a JavaScript framework that can add HTML and CSS. Angular is developed in Typescript for a bug-free experience.

Angular was developed in 2008 and Flutter was developed in 2017 so, Angular is a better framework than Flutter because it is more stable and older.


Flutter performs better than angular because of its rendering engine, skia, and usually provides us FPS(frame per second) between 60fps to 120fps as animation standards.

But in angular, it uses Ivy as a rending engine which generally performs less and there are lots of libraries, functionality, and tools that make its size larger. So cause a negative effect on its performance.

Cost Efficient 

In Flutter vs Angular, Flutter is more cost-efficient than Angular. Flutter is used for cross-platform and uses native code that runs for both android and IOS while in Angular developers have to develop two different codes.

Also, Flutter code can be updated easily and, in less time, but for angular developers providing updates is a very complex process that takes a lot of time.


Angular is more popular than Flutter. Angular comes in 2007 so, it has a lot of developers and many companies believe in Angular security tools for developing bug-free apps. Flutter is new in the market, it’s also gaining popularity because of simple and fast UI development.

Scalability and flexibility

Angular provides more scalability for frontend development because of its tools and scale components. While Flutter is less scalable but has better flexibility for cross-platform development, on the other hand, angular is less flexible in cross-platform development. 

Community and Ecosystem

In Flutter vs Angular, the Angular community is bigger than Flutter because Angular is in the market for a long time while Flutter is younger and developing its community and Ecosystem gradually. Flutter’s popularity is growing exponentially which makes it famous in very less time.

Reasons to Choose Flutter and Angular 

Choose Flutter If

  • Your app does not necessitate native functionality.
  • A user-friendly and customizable UI with widgets is required.
  • You will require a single codebase that supports several platforms.
  • You want to write code rapidly and get your product out there as soon as possible.
  • You’ll need an app that can run at 60 to 120 frames per second.

Choose Angular, if

  • Your app requires native Functionality 
  • You want ready-to-use custom components for the app
  • You want to develop a truly secure app with code details and testing
  • You can make Scalable Websites


Each of them has its own advantages and disadvantages, so the end decision that you take should be based on your business requirements. Even though we have listed out major differences between each of these, all of them have powerful features which can help you build brilliant mobile applications.  

Both flutter and Angular are very popular technologies that let you develop interactive applications. Angular makes JavaScript a client-side framework where the developers create attractive web applications using the MVC architecture. 

At the same time, flutter is very user-friendly and provides less complicity to developers for scalable applications.
