This treats whether or not to use the forked NNBD SDK as a build flag similar to mode or architecture. When this flag is passed, it appends "NNBD" to the main output directory, like xcodebuild/ReleaseX64NNBD. It also defines a "use_nnbd" flag that is available inside BUILD.gn files to determine whether or not to use the forked SDK. This flag currently isn't used. Implementation teams will need to edit their build steps to take that into account. In order to use this mode on the bots, we'll need to tweak the bot scripts to figure out whether the mode is enabled or not. There are a couple of TODOs in the Python scripts for that. I'm not sure how that should be specified in dart_sdk.py. This CL does not remove my previous change to allow building the NNBD fork next to dart-sdk in the same root output directory. I'll revert those changes in a different CL once this one lands.

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).
