dependencies_field_not_map

The value of the '{0}' field is expected to be a map.

The analyzer produces this diagnostic when the value of either the dependencies or dev_dependencies key isn't a map.

The following code produces this diagnostic because the value of the top-level dependencies key is a list:

name: example
dependencies:
  - meta

Use a map as the value of the dependencies key:

name: example
dependencies:
  meta: ^1.0.2
