Google today released Dart SDK version 1.4 with a new Observatory tool that allows you to look inside a running Dart virtual machine on demand and see live reporting of data. It shows information about garbage collection, the instance count for all in-memory objects by their type, line-by-line code coverage, and evaluation of arbitrary expressions. You can download the latest stable release of Dart, the company’s JavaScript competitor, now from dartlang.org.
In Dart 1.4, the dartanalyzer command line tool is 100 percent Dart, meaning it runs without Java and requires only the Dart virtual machine. Google has also made File I/O much faster, especially when accessing large files, and added experimental support for sharing network sockets across isolates (on Linux only for now). You can read the full release notes here.
