Dart is the language you use to write cross-platform applications in Flutter. You're not limited to Flutter, though. You can also use Dart to write command-line and backend server applications. The official documentation is great, but it doesn't go into the depth or provide all the examples that a book can.

Dart Apprentice: Beyond the Basics is here to help by building on your foundational knowledge of the language as you grow to become a fully proficient Dart developer.

Dart Apprentice: Beyond the Basics is for developers who already know the fundamental concepts of programming in Dart but want to take their skills to the next level.

• String Manipulation: Searching and changing text with regular expressions.
• Anonymous Functions: Passing functions around as first-class citizens.
• Object-Oriented Programming: Using inheritance, abstract classes and interfaces.
• Mixins: Sharing code between classes.
• Extension Methods: Adding features to classes that don't belong to you.
• Generics: Making your classes and functions handle multiple types.
• Enhanced Enums: Letting your enums act more like classes.
• Error Handling: Planning for what might go wrong.
• Asynchronous Programming: Using futures and streams to handle long-running tasks.
• Isolates: Running code in parallel.

One thing you can count on: After reading this book, you'll be prepared to learn Flutter or server-side app development in Dart.
