Mixins vs Extensions in Dart

The Major Differences

• Mixins allow for an adapted multiple inheritance.
  • Though they have the limitation that you cannot have mixins inheriting mixins.
• Extensions let you add new methods to a class but not state (new instance variables).
  • But you can use stuff like the Expando object.
  • They can't override methods either.
