Flutter vs Java: Which is Best for Android App Development?


Check Out the Flutter Vs Java Comparison and select the Best for You

Mobile development is an ever-growing as well as an ongoing development field that provides and has given many possibilities and opportunities. The majority of programmers as well as developers tend to become mobile developers as a result of a wide range of opportunities presented to them in this mobile development vertical as well as the languages that exist to support these mobile development efforts. The numerous resources present and provided to developers may mislead someone with little or no experience. Let’s understand below about Flutter vs Java.

Flutter vs Java is primarily classified as the major and most used “Cross-Platform Mobile Development” and “Languages” tools respectively. Java developers prioritize great libraries, but Hot Reload is the primary factor influencing their choice of Flutter over its competitors.

Flutter is an open-source tool and a development framework with 69.5K GitHub stars and 8.11K GitHub forks. Here’s a link to Flutter’s open-source repository on GitHub.

Java is widely used by prominent businesses like Spotify, Uber Technologies, and Airbnb, while Flutter is used by Hybrid Heroes, Policygenius, and Pludoni GmbH.



A Cross-platform mobile framework developed and supported by Google. Flutter is a mobile app software development kit to help developers, programmers and designers build modern mobile apps for both emerging iOS and Android platforms.

With Flutter, you are able to build native mobile applications for both Android and IOS, using the Dart language. Being released in 2017, Dart is a little bit new right now, but in the case of Flutter, a strong competitor for his older brother React Native. It is predicted that with the passage of time, Flutter is going to be used in the majority of apps. Apart from mobile development, flutter can also be used for the web as well as desktop applications.

Flutter is a technology that supports cross-platform development. Google’s latest toolbox simplifies app creation, but Java support for Android applications is decreasing. Developers are now favouring Flutter for cross-platform applications, a shift in perspective. These apps run smoothly and efficiently as well as provide the same native app-like performance.



Java is a general-purpose as well as concurrent, class-based,  object-oriented language that is specifically designed to have as few implementation dependencies as possible. Sun Microsystems debuted Java, a programming language and computing platform, in 1995. It is renowned for its dependability, speed, and security. From laptops to data centres, as well as many game consoles to scientific supercomputers, cell phones and the Internet, Java is everywhere!

Java is an object-oriented programming language built to support mobile development for almost 10 years now. Since the appearance of Flutter as well as React Native, Java had a monopoly on Android app development. However, Google now appears to be moving towards Kotlin. Even in this case, Java Android API is stable as well as well documented.

Before the advent and invention of Flutter, Java was the officially adopted language for Android app development. However, there was a serious drawback when using Java. As developers, you would not have got the cross-platform capabilities and better performance that Flutter provides when you used Java as the primary platform for developing apps. Thus you also had to spend more money and resources when you wanted to develop cross-platform apps that run smoothly and efficiently on multiple platforms such as Android, iOS and Windows mobile. Google has successfully resolved issues with Flutter’s creation and has announced that it will become the official platform for creating cross-platform apps.

Flutter vs Java


Cross-platform app development:

  • Designing apps for both Android as well as IOS platforms with a single code base is an extremely important and useful feature for developers.
  • This may be the biggest difference between Java and Flutter.
  • Java only supports Android development whereas Flutter provides and is able to give a single code base for both Android and IOS.


Development Speed:

  • Developing apps with Flutter can bring you more results in less time when you compare this with Java.


Resources and Documentation:

  • Because Flutter is around and it is all about mobile app development.
  • The online documentation and resources introduced nearly three years ago are not directly comparable to Java. As a result, if you have a problem or an unusual bug or issue in your program,  it is more likely to find some relevant information on the internet when you make use of programming in Java than Flutter.


One Code Base, Multiple Platforms:

  • When you develop apps using Flutter, you only have to use a single code base to develop apps for Android and iOS.
  • On the other hand, if you use Java, you can develop only for the Android platform.
  • As you know two is better than one, leverage flutter to develop apps on multiple platforms.


Reduced Cost:

  • Using Flutter you can reduce your app development costs by up to 50%.
  • Not only this but also the time taken to develop the app reduced drastically.
  • So you should use Flutter so that you can have the best app development experience possible.


Flutter vs Java for Android



Flutter is a development tool or platform tool for cross-platform apps. Java is used for Android app development and Java-specific apps. 
Dart programming is used for writing applications. Java is the universal programming language and has a variety of uses. 
Flutter provides close to native-performance.  Java delivers native performance. 
Flutter is a bit cost-effective. Developing apps in Java is not that cost-effective
Flutter apps only Andriod and ios  Java apps run on any system due to the JVM. 
The Flutter documentation is not that. exhaustive. The Java documentation is exhaustive & detailed. 
It does not support OOPs but is relatively new. It supports OOPs, and is relatively mature.


Is Flutter better than Java?

  • To begin with, the performance of both, Java and Flutter don’t share any common ground, as Flutter is a UI development kit whereas Java is a programming language.
  • In terms of developer popularity, Java has one of the widest and most devoted user bases.
  • Flutter is a superior framework as its apps outperform those built using other frameworks.
  • Furthermore, due to capabilities like as Hot Reload and Restart, it has quite fast development and debugging tools.


Can Java replace Flutter

  • Flutter has the potential to take over Java in mobile app development.
  • Flutter can simplify the development process as it offers numerous features and widgets that are not only accessible in native Android app development. 
  • It would be difficult to predict whether Flutter will replace Java because there is still potential for development and refinement, but there is no doubt that it is the greatest framework currently in the market for making app development easier, faster, and cost-effective.


Is Flutter enough for Android development?

  • For creating a minimum viable product Flutter seems to be a good option whenever time constraints are present for companies to push the product to the market as soon as possible.
  • Significant benefits include code documentation, widgets, and animation speed.
  • There are special functionalities available in the Flutter framework that are not available on any other platform.
