Can someone help me get a general idea of what dart and angularDart is?

I was going through the Dart documentation and i realised that Dart actually offers various functionalities for web, App development and developing servers. As per my understanding it is a language which can bind various features of web. Is it like a complete package of webdevelopment? And does angularDart mean i can write code in angular along with maintaining the connections between different Dart applications? Thanks.
