For Java developers

Same principles. New platform.

Dart's type system, OOP model, and null safety will feel like home. Learn Flutter through interactive exercises that respect what you already know.

Classes, generics, async/await, strong typing. You'll write Dart fluently within days, not months.

You know the principles. Our courses apply them to Flutter's widget architecture so the patterns transfer immediately.

Flutter compiles to native. No webview, no bridge. One typed codebase that runs everywhere.

Dart + Flutter + SOLID + DRY

From enterprise Java to cross-platform apps.
