  • I think that it would also be cool to introduce the cascading operator to retain the type that we want: Method Cascades in Dart

  • On Strings, it’d be cool to also mention that we can use methods inside${variable.getProperty()}

  • Might be a stretch, but mixins are very powerful and could be introduced here

  • Also new functions for the language such as spread operators: flutter - How to spread a list in dart - Stack Overflow

  • And a final note: const vs var vs val vs final vs specifying the type, showing all the different alternatives
