One of the irritating problems with sockets is a sudden loss of connection. If the true cause is not visibly evident, i.e., unstable internet connection, then the disruption cause is often well hidden.

Let’s begin!

What’s in store for Dart 2.5 as a programming language?

Dart is a Google borne programming language that has been used to develop mobile, web and desktop based applications. It is an object-oriented, class defined, garbage collected language with a C-style syntax, which is used to optionally compile into JavaScript.



The latest version of Dart 2.5 comes with these major highlights:
