20:47:35 What Is Dart?
Dart Programming Language
Dart is a client-optimized programming language created by Google, primarily used with the Flutter framework for building cross-platform mobile, web, and desktop apps from a single codebase. It compiles to native ARM code for mobile and JavaScript for web.
How Dart Works
Dart is inseparable from Flutter — almost nobody uses Dart without Flutter. The language features async/await, sound null safety, mixins, and hot reload for instant development feedback. It compiles to native code on mobile and JavaScript on web.
Key Concepts
- Sound Null Safety — Dart's type system guarantees that non-nullable variables can never be null — prevents crashes at compile time
- Hot Reload — See code changes instantly without losing app state — dramatically speeds up mobile development
- AOT Compilation — Dart compiles to native ARM code for production — no interpreter overhead on mobile devices

Frequently Asked Questions
Should I learn Dart without Flutter?
Probably not. Dart's ecosystem is almost entirely Flutter-based. If you want to build cross-platform apps with Flutter, learn Dart. Otherwise, JavaScript, Python, or Go are more versatile choices.
Is Dart like JavaScript?
Somewhat. Dart has similar syntax (C-style), async/await, and classes. But Dart is statically typed, compiled, and has sound null safety. It feels like a cleaner TypeScript.
