Introduction
Cross-platform is a technique that more and more companies and developers are starting to think is worth trying. Technologies and frameworks for cross-platform programming are growing in popularity, and the reasons behind it are quite understandable such as reduced cost, quick time-to-market, and a single codebase for multiple platforms. Today it is one of the important trends in the software development world.

No framework or programming language is perfect. Each one has its pros and cons. Flutter and Kotlin offer the best performance and significantly save development time and cost.
This blog will look into the features, advantages, disadvantages, and basic differences between Flutter and Kotlin. Are you eager to know which framework will win this flutter vs kotlin battle? Then let’s go!
Flutter
The Flutter is a cross-platform software development kit introduced by Google in 2015 and released in 2017. Flutter is a software development framework for creating high-performance, high-quality apps from a single Dart Language codebase for iOS, Android, Web (beta), and desktop applications.

Flutter provides a simple, powerful, efficient, and straightforward SDK for developing mobile applications in Google's language, Dart. Dart is an object-oriented programming language with C-style syntax created by Google in 2011. Dart programming is used to construct front-end user interfaces for online and mobile apps.
Uses of Flutter
- Flutter can create small, mid-size, and large-size apps for retail businesses.
- When time and resources are limited, flutter is a great option for creating an MVP and prototyping apps.
- It can be used to make a full-fledged mobile application.
- The flutter framework can create solutions where user engagement is a must, such as FinTech apps, enterprise apps, businesses, banks, and online stores.
Advantages of Flutter
For a high-performance and excellent mobile application, flutter comes with gorgeous and customizable widgets. It satisfies all custom requests and specifications. Flutter also has several other advantages, which are listed below.
- Declarative and expressive UIs
- Native performance
- Stateful hot reload makes app development faster.
- Full-customization of widgets
- Reduced cost and time
- For Android and iOS platforms, developers only need to write a single codebase.
- Flutter requires fewer tests.
- Its flexibility to be customized and extended makes it even more powerful.
Disadvantages of Flutter
Despite its many benefits, flutter has the following cons:
- The limited set of tools and libraries
- Framework for developing mobile apps
- Large file sizes
- Lack of third-party libraries and integrations
- Prior knowledge of dart language
- Lacks password management support
- Performance issues on iOS
