No, it is not possible . Dart and Java are different languages that both run in their own VM. You can however invoke java via the Process class. There is also a Java to Dart plugin that is in an experimental phase.

No . Dart is easy and purposefully similar to java/JS/c#.

It’s is a compiled language like C, so it’s way faster than Java anyway . Dart is also approximately 2x faster than Javascript. It’s type-safe and compiled with both AOT and JIT compilers (to learn about the benefits of that, keep on reading ).
