Dart is easy to use and understand, it's syntactically more readable. My cause for learning dart was because I wanted to develop app that can be run on both android and iOS and that can be achieved using Dart and Flutter. We just need to write one code and it will work for both android as well as iOS.

Easy to learn. Google's flutter is based on dart, which makes cross platform application development experience much amazing.

Dart is being used in flutter which forced me to learn dart first. i am glad that i did.
