Dart is somehow close to Javascript & Kotlin, which made it very easy for me to start working with Flutter. The ease of use, fast development process, hot reload and hot restart. Pub libraries are very easy to use and manage, along with making our own libs.

Been using dart for past two years. Its been a good experience. Dart is used in flutter which is a Google managed framework which is used to build both android and iOS using single codebase.

I used java for 2 years but now when I am using dart it's so much better than other technologies it's easy and powerful. I like the code flow speed and use of plugins.
