How do you evaluate the innovations and capabilities of Dart 2.0 compared to previous versions?

Dart 2.0 brought several important improvements over previous versions:

• Sound null safety — helps avoid null-related errors at compile time.
• Improved performance — compiler and runtime optimizations.
• Support for new syntactic constructs — for example, extended capabilities for functions, collections, and classes.
• Better integration with Flutter — Dart 2.0 became the foundation for modern Flutter, providing more stable and faster development.

Overall, Dart 2.0 made the language safer, more expressive, and more performant, which positively impacted mobile app development.
