do_not_use_environment

Do not use environment declared variables.

Using values derived from the environment at compile-time, creates hidden global state and makes applications hard to understand and maintain.

DON'T use fromEnvironment or hasEnvironment factory constructors.

BAD:

const loggingLevel =
  bool.hasEnvironment('logging') ? String.fromEnvironment('logging') : null;

To enable the do_not_use_environment rule, add do_not_use_environment under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - do_not_use_environment

If you're instead using the YAML map syntax to configure linter rules, add do_not_use_environment: true under linter > rules:

linter:
  rules:
    do_not_use_environment: true
