Todd Volkert 9173aed1ba Declare return types of Uint8List. 
These methods all were returning Uint8List, yet they were only
declared to return List<int>. This forced callers to either defensively
wrap the return values in Uint8List, or to assume the contravariant
return value:

* Utf8Codec.encode()
* BytesBuilder.takeBytes()
* BytesBuilder.toBytes()
* File.readAsBytes()
* File.readAsBytesSync()
* RandomAccessFile.read()
* RandomAccessFile.readSync()
* Uint8List.sublist()

Since it's related, this change also updates the following sublist()
methods to declare that they return the a sublist of the same type as
the source list:

* Int8List
* Uint8ClampedList
* Int16List
* Uint16List
* Int32List
* Uint32List
* Int64List
* Uint64List
* Float32List
* Float64List
* Float32x4List
* Int32x4List
* Float64x2List

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web

Dart has flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
