Add SHA-512 support to the crypto library

What steps will reproduce the problem? The current crypto library only supports SHA-1 and a limited subset of SHA-2 (SHA-256). While this may be enough for client-side, it would be nice to have full SHA-2 support for server-side development. This would mean support for all SHA-2 algorithms: (SHA-224, SHA-256, SHA-384, SHA-512).
What is the expected output? What do you see instead?
What version of the product are you using? On what operating system? Dart SDK version 0.4.5.1_r21094
Please provide any additional information below. I was looking to write a server-side program that talked to a RESTful service, but it required that all requests had a SHA-512 signature, which is not currently supported by the included Dart crypto library. I could also see this being needed for anyone doing a server-side Dart app that wants to store SHA-512 versions of users passwords.

I'm working on these changes. I have SHA-224 and SHA-512 added and working. I have a bit of work to get all the tests added that I need/want to do.

Removed Area-Library label. Added Area-Pkg label.
This would be more than welcome since more and more API require this level of security.
Trying to implement this in my project, but something is wrong 🤔 Could anyone guide me to the right direction? I'm thinking about sending PR, once it's completed.
https://github.com/yshrsmz/bip39-dart/blob/58f51d08166929c4fb7612871e4e3506a5c2a3d1/lib/src/sha512.dart
it's based on https://github.com/jwendel/dart-sha-2
How is it going @yshrsmz ? Can I use the sha512.dart file in my project, is it ready?
@SoptikHa2 Sadly no, but I'm now using https://github.com/PointyCastle/pointycastle/ It was not Dart2 compatible at that time, but now it is.
