This is just a #off-topic question. I was just curious because I’m learning flutter.
Thunkable X is based on a different technology - React Native, but with Thunkable X you can learn programming. But I can say so, if you plan to use Javascript when developing applications on Thunkable X, then you will see that knowledge of Dart can be useful to you in this.
Thanks for the reply. Now my doubts are clear.
