depend_on_referenced_packages

Depend on referenced packages.

DO depend on referenced packages.

When importing a package, add a dependency on it to your pubspec.

Depending explicitly on packages that you reference ensures they will always exist and allows you to put a dependency constraint on them to guard you against breaking changes.

Whether this should be a regular dependency or dev_dependency depends on if it is referenced from a public file (one under either lib or bin), or some other private file.

BAD:

import 'package:a/a.dart';

dependencies:

GOOD:

import 'package:a/a.dart';

dependencies:
  a: ^1.0.0

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

linter:
  rules:
    - depend_on_referenced_packages

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

linter:
  rules:
    depend_on_referenced_packages: true
