[native_assets_cli] Is there any way to pass environment variables/command line arguments to hook/build.dart?

[nmfisher]

It would be nice to read environment variables to set build-time parameters. Log levels are a good example, like:

    final cbuilder = CBuilder.library(
      defines:{"TRACE":Process.environment["TRACE"]}

or from CLI parameters, ala:

dart --enable-experiment run lib/app.dart --trace=1

Is this currently possible? All of the following seem to have stripped anything relevant:

const trace = String.fromEnvironment("TRACE");
Platform.executableArguments
Platform.environment

This may be a duplicate of #39

Generally our thinking was that we'd want to do this in more controlled fashion. A package's hook can decide flags it offers and end-users could configure that particular package's flag when building. e.g.

% dart run \
  -B package.<pkgfoo>.debug=true \
  -B package.<pkgbar>.cppAsserts=true \
  ... \
  foo.dart

Possibly allowing to persist such flags for an application package in pubspec or other file.
