- ▸Server-side applications with Dart VM
- ▸Command-line tools and scripts
- ▸Cross-platform desktop applications
Notable Features
- ▸Strongly typed with sound null safety
- ▸Ahead-of-time (AOT) and just-in-time (JIT) compilation
- ▸Hot reload for fast development cycles
- ▸Rich standard library and asynchronous support
- ▸Interoperability with JavaScript for web development
Origin & Creator
Created in 2011 by Google, designed by Lars Bak and Kasper Lund.
Industrial Note
