constant_identifier_names

The constant name '{0}' isn't a lowerCamelCase identifier.

The analyzer produces this diagnostic when the name of a constant doesn't follow the lowerCamelCase naming convention.

The following code produces this diagnostic because the name of the top-level variable isn't a lowerCamelCase identifier:

const EMPTY_STRING = '';

Rewrite the name to follow the lowerCamelCase naming convention:

const emptyString = '';
