Yes! As mobile app developers are constantly seeking ways to create applications that are feature-rich, user-friendly, and optimized in size. This is where Flutter, Google’s open-source UI toolkit, stands out. In this article, we will explore why Flutter apps’ compact size matters in today’s mobile app landscape.
Dart Language
Flutter uses Dart as its programming language, which is designed to be fast and efficient. Dart is a compiled language, and its byte code can be compiled to run natively on multiple platforms, such as Android, iOS, and the web. This allows Flutter apps to have a smaller file size since there is less need for third-party libraries and additional resources.
Widgets
Flutter uses a reactive programming model where widgets update in response to app state changes. This allows Flutter to use a minimal number of devices to create an interface, which helps reduce the size of the app.
Flutter includes a rich set of pre-built widgets that can be customized according to the application’s needs. These widgets are designed to be flexible and adaptable to different screen sizes and resolutions. By using these widgets, developers can avoid creating custom design elements, which can add to the app’s size.
AOT Compilation
Flutter apps are compiled ahead of time (AOT), which means the code is compiled into machine code before the app is installed. This process reduces the app’s load time and makes it more efficient.
Tree Shaking
Flutter includes a feature called “tree shaking,” which eliminates unused code and resources from the final binary. This helps reduce the size of the app even further.
Customizable Packages
Flutter includes a vast collection of customizable packages that can be used to build apps quickly and efficiently. These packages are lightweight and can be easily integrated into the app, reducing the app’s size.
Flutter supports tree shaking.
Tree shaking is a process that removes unused code from the application during the build process. Flutter’s tree-shaking process ensures that only the code necessary for the app is included in the final build, reducing the app’s size.
Flutter allows for selective rendering.
Flutter’s widget tree architecture enables the selective rendering of widgets, which means that only the widgets that need to be updated are rendered instead of the entire widget tree. This reduces the amount of code that needs to be executed, leading to faster app performance and smaller app size.
Flutter uses Ahead-Of-Time (AOT) compilation.
Flutter’s AOT compilation enables the app to be compiled ahead of time into machine code, which reduces the size of the app by removing unnecessary code that is not required during runtime.
Flutter uses a compiled programming language.
Flutter utilizes the Dart programming language, which is compiled into native ARM (Advanced RISC Machine) code, enabling it to run natively on iOS and Android devices. This eliminates the need for an additional runtime, which can add to the app’s size.
Flutter is a mobile application development framework created by Google. One of the critical advantages of Flutter is that it allows developers to create highly performant apps that are smaller in size than their counterparts built using traditional native app development approaches.
Here are some of the reasons why Flutter apps are smaller in size:
No need for separate UI and logic codes
Unlike traditional native app development, where the UI and logic codes are developed separately, Flutter allows developers to write both UI and logic codes in a single language. This eliminates the need for separate codebases, reducing the overall size of the app.
Smaller libraries
Flutter apps use a smaller number of libraries compared to native apps. This is because Flutter has its own library set that provides all the necessary functionalities required to build an app.
JIT/AOT Compilation
Flutter uses Just-In-Time (JIT) compilation during the development phase, which allows developers to see the changes they make to the code in real-time. During the production phase, Flutter uses Ahead-of-Time (AOT) compilation to compile the app’s code into native machine code, making the app faster and smaller.
Code sharing
Flutter uses a single codebase for both iOS and Android platforms, which reduces the amount of code required to be written. This results in a smaller app size.
Native Performance
Flutter compiles the code into native ARM code, which results in faster performance and a smaller app size.
Smaller runtime
Flutter uses a smaller runtime that reduces the size of the app.
The Bottom Line!
All of these factors make Flutter apps smaller than their counterparts. However, the actual app size can still vary depending on various factors, such as the number of assets used, the complexity of the app, and the features required by the app. Reach out to CodeEpsilon which provides the most realistic and accurate Flutter development solutions and builds your apps progressively.
