Flutter vs Kotlin: What are the differences?
Flutter can be classified as a tool in the "Cross-Platform Mobile Development" category, while Kotlin is grouped under "Languages".
"Hot Reload" is the primary reason why developers consider Flutter over the competitors, whereas "Interoperable with Java" was stated as the key factor in picking Kotlin.
Flutter and Kotlin are both open source tools. Flutter with 69.5K GitHub stars and 8.11K forks on GitHub appears to be more popular than Kotlin with 28.3K GitHub stars and 3.29K GitHub forks.
According to the StackShare community, Kotlin has a broader approval, being mentioned in 268 company stacks & 210 developers stacks; compared to Flutter, which is listed in 42 company stacks and 146 developer stacks.

For a front end dev like me, using a mobile framework for side projects makes more sense than writing a native app. I had used Apache Cordova (formerly PhoneGap) before (because React Native didn't exist yet), and was happy with it. But once React Native came out, it made more sense to go that way instead. It's more efficient and smooth, since it doesn't have the simulation overhead, and has more access to hardware features. It feels cleaner since you don't need to deal with #WebView, using native UI widgets directly. I also considered Flutter . It looks promising, but is relatively new to the game, and React Native seems more stable for now.
As the WeWork footprint continued to expand, in mid-2018 the team began to explore the next generation of identity management to handle the global scale of the business.
The team decided to vet three languages for building microservices: Go, Kotlin, and Ruby. They compared the three by building a component of an identity system in each, and assessing the performance apples-to-apples.
After building out the systems and load testing each one, the team decided to implement the new system in Go for a few reasons. In addition to better performance under heavy loads, Go, according to the team, is a simpler language that will constrain developers to simpler code. Additionally, the development lifecycle is simpler with Go, since “there is little difference between running a service directly on a dev machine, to running it in a container, to running clustered instances of the service.”
In the implementation, they the Go grpc framework to handle various common infrastructure patterns, resulting in “in a clean common server pattern that we can reuse across our microservices.”

- Desktop: And Electron to ship it as a desktop application.
- Android: a mix of Java and Kotlin.
- iOS: written in a mix of Objective C and Swift.
- The core application and the API written in PHP/Hack that runs on HHVM.
- The data is stored in MySQL using Vitess.
- Caching is done using Memcached and MCRouter.
- The search service takes help from SolrCloud, with various Java services.
- The messaging system uses WebSockets with many services in Java and Go.
- Load balancing is done using HAproxy with Consul for configuration.
- Most services talk to each other over gRPC,
- Some Thrift and JSON-over-HTTP
- Voice and video calling service was built in Elixir.
- Built using open source tools including Presto, Spark, Airflow, Hadoop and Kafka.
I am starting to become a full-stack developer, by choosing and learning .NET Core for API Development, Angular CLI / React for UI Development, MongoDB for database, as it a NoSQL DB and Flutter / React Native for Mobile App Development. Using Postman, Markdown and Visual Studio Code for development.
Even though still a young language, it feels so at home sitting in the springboot frame and works with vaadin just great. And in itself it has like all the best parts of java, scala, python mixed into one.
We use Kotlin both in our Android App and increasingly in our polyglot backend services.
