What does the pubspec.yaml's environment mean in this context?

I notice the environment variable in the intl package's pubspec.yaml says that it supports between the sdk '1.4.0 to 2.0.0'

I found the description of the environment variable here

But, That particular version's numer_format.dart has the null aware operators that are not introduced until 1.12.0.

Am I understanding the definition of the pubspec's environment variable correctly?

Thanks

environment:
sdk: ">=2.16.1 <=3.1.0"

This means the Dart SDK version.

packages & dependencies of your project must be supported above the SDK range.

environment:
  sdk: '>1.3.0 <= 2.0.0'

is not related to operating system environment variables, it is just a constraint for the environment where the package is supposed to work, and the only setting currently supported is the Dart SDK version. The version range is according to the semantic versioning used in Dart for the SDK and pub packages.

You are correct the SDK constraint should be modified to something like >=1.12.0 <2.0.0. You can file an issue (or even better submit a Pull-request).
