Siva Annamalai 63a92a3b00 Revert "This is a trial submit of the unfork CL, it will be reverted immediately."
This reverts commit 393468dc89.

Reason for revert: This was a trial submit and so reverting it.

Original change's description:
> This is a trial submit of the unfork CL, it will be reverted immediately.
> This commit is being done so we can roll it into Flutter and run some device lab testing to see the effect this CL will have on Flutter.
> 
> [BUILD] - Initial CL to unfork the NNBD Dart SDK
> 
> - Flips the flag from --nnbd to --no-nnbd so that by default it builds
>   the NNBD version
> - using the --no-nnbd flag results in the SDK being built in a
>   directory which has the 'Legacy' suffix added to it
>   (e.g: out/DebugX64Legacy)
> - the '--enable-experiment=non-nullable' flag still needs to be passed
>   in during execution so that CFE runs in that mode. This is different
>   from the 'null_safety' flag
>

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's 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).
