Why Should You Use A Go Backend In Flutter?

Flutter is a well-known open-source framework for developing cross-platform applications for Android, iOS, Linux, macOS, Windows, Fuchsia, web, and other platforms. Flutter is becoming increasingly popular due to its performance and built-in platform-independent UI widgets. Go is a high-performance, compiled, statically typed language with a simple syntax.

Flutter and Go gained popularity among developers after Google launched both open-source projects. Many developers nowadays prefer to use Go and Flutter in tandem. Using a Go backend for a Flutter frontend has numerous advantages.

What is Flutter?

Flutterby Google is an open-source UI software development kit. It is used to create cross-platform applications for Android, iOS, Linux, macOS, Windows, and the web using a single codebase. The first version of Flutter, dubbed “Sky,” ran on the Android operating system. It was first revealed in 2015 at the Dart developer summit. Flutter 1.0, the framework’s first stable version, was released on December 4th of that year at the Flutter Live event. Flutter’s most recent stable release, version 2.10, was on March 2, 2022.

Reasons, why Flutter is ideal for your future application programs, are mentioned below

  • Flutter’s code is the same across platforms. Whether it’s iOS, Android or any other Linux kernel-based operating system
  • Flutter has a hot reload feature that allows designers and developers to see changes immediately and make changes as needed.
  • Flutter documentation is clear, simple and easy to understand.
  • Flutter provides impressive and unique widgets.
  • Since it is an open-source SDK supported by Google, it has a large global community.
  • The compatibility of Flutter with various operating systems is excellent.
  • It accelerates development and problem-solving processes.

What is go Backend?

Go, also known as Golang, is a programming language that is open-source, statically typed, compiled, cross-platform and lightning-fast. It was first introduced by Google in 2009. Go is a versatile language that is ideal for backend development. Google developers wanted to combine the best features of existing languages while addressing their most common issues. Go, like C++ and Java, is a statically typed, high-efficiency language. In terms of syntax and speed, Go is similar to C. It’s a straightforward language that enables developers to write readable and maintainable code.

In 2011, the first stable version of Go was released, offering developers a robust goroutine, a garbage collector, and an embedded testing environment. Go has become extremely popular in the developer community thus far.

Advantages of go Backend in Flutter

Flutter frontends benefit from numerous nontechnical and hidden advantages provided by Go-based backends. Furthermore, by directly using Go modules in the Flutter app, you can avoid time-consuming business logic rewrites. Let’s take a look at them

  • Trends, community and popularity

Go and Flutter are both open-source projects developed by Google. Both projects are supported by the Google open source community, which provides free community-based developer support, contributes code, and creates resources. Google released Go v1 in 2012 and Flutter v1 in 2018, but by late 2019, both technologies had experienced rapid growth for cloud-based business applications. Both projects are rapidly gaining popularity and come with an excellent reputation, community support, and cutting-edge, Google-engineered technology.

  • Identicalities in the Development Environment

Go is the cross-platform application development language used by Flutter. Flutter and Go both have features for dealing with various technical issues. However, there are many similarities between Go/Flutter syntax, developer tools and third-party libraries. As a result, the same full-stack development team can work on both backend and frontend projects without compromising productivity. Because of Go’s minimal syntax, Flutter developers can easily get started with backend development in Go. Furthermore, Go development tools are fully compatible with all Flutter development tools’ operating systems. As a result, on your Flutter development computer, you can set up a productive Go development environment.

  • Go and Flutter are high-performance Technologies

Because of powerful computer hardware components, some developers nowadays tend to overlook application performance. Because many people use powerful computers and mobile devices, hybrid apps do not exhibit performance issues, despite the fact that they perform slower than native apps. Furthermore, because of the robust cloud computing infrastructure, many web developers rarely need to optimize web backend performance. By carefully considering performance factors, both the Go and Flutter projects strive to solve the primary technical problem.

The Go compiler generates fast and optimized native binaries, allowing Go to be as quick and agile as other modern, popular enterprise-level programming languages such as C#, Java, and JavaScript (Node.js). Furthermore, a Go backend provides Flutter applications with fast and efficient native server-side services, allowing them to achieve better native performance.

  • Flutter uses Go backend logic

Backend code must sometimes be reused directly in a frontend application. You can easily share common business logic if you use Node.js for the backend and React Native for the frontend by creating a JavaScript package. However, Dart’s server-side support is still in its early stages and is not yet comparable to the Go ecosystem, so you should think twice before using Dart to write the backend. If you develop your backend in C#, Java, or Node.js, you may need to rewrite the same existing business logic in Dart on the Flutter frontend. The Go mobile project provides a method for calling Go code from platform-specific mobile development environments such as Java and Android.


Therefore, it is safe to say that when it comes to high-load enterprise-level projects and even microservices, Go Backend is ideal for Flutter.
