Sam Rawlins 7cad5f5e52 analyzer: Improve names of unused_element parameter tests
We don't have a strict rule set for naming test methods, but the general
idea of grouping terms with underscores (and breaking an otherwise
rather universal rule of using camelCase) is to help to group like
test cases (aided by our alphabetical sorting enforcement).

There were examples in this file that really broke the grouping
mechanism by not using consistent grouping. Here are the broad strokes
of what I changed; no test bodies were changed, _only names_, but the
CL is hard to review because of sorting.

* `test_classGetterSetter_...` and `test_classSetter_...` were renamed
  to use `class` as a group (`test_class_getterSetter_...` and
  `test_setter_...`) consistently.
* `test_factoryConstructor_...` were renamed to use `constructor` as
  the group base (`test_constructorFactory...`).
* `test_optionalParameter_...` were renamed to use `parameter` as the
  group base (`test_paramter_...`). This is the bulk of the change.
  There were previously dozens of tests starting with
  `test_optionalParameter_` _and_ dozens of tests starting with
  `test_parameter_`. However, `unused_element` only concerns itself
  with optional parameters, so that can be the default meaning of
  `test_parameter_`. (Similar to classes; we don't report any public
  classes as unused, but we don't need to write `private` in every
  test case.)
* In the parameter tests, there was an inconsistent placement of the
  group `isUsed` or `notUsed`. It seems like the bulk of tests place
  the `isUsed` or `notUsed` grouping earlier rather than at the end of
  the test name, so I went with that for this consistency CL.

pub package package publisher

This package provides a library that performs static analysis of Dart code. It is useful for tool integration and embedding.

End-users should use the dart analyze command-line tool to analyze their Dart code.

Integrators that want to add Dart support to their editor should use the Dart Analysis Server. The Analysis Server API Specification is available. If you are adding Dart support to an editor or IDE, please let us know by emailing our list.

Configuring the analyzer

Both dart analyze and Dart Analysis Server can be configured with an analysis_options.yaml file (using an .analysis_options file is deprecated). This YAML file can control which files and paths are analyzed, which lints are applied, and more.

If you are embedding the analyzer library in your project, you are responsible for finding the analysis options file, parsing it, and configuring the analyzer.

The analysis options file should live at the root of your project (for example, next to your pubspec.yaml). Different embedders of analyzer, such as dart analyze or Dart Analysis Server, may choose to find the file in various different ways. Consult their documentation to learn more.

Here is an example file that instructs the analyzer to ignore two files:

analyzer:
  exclude:
    - test/_data/p4/lib/lib1.dart
    - test/_data/p5/p5.dart
    - test/_data/bad*.dart
    - test/_brokendata/**

Note that you can use globs, as defined by the glob package.

Here is an example file that enables two lint rules:

linter:
  rules:
    - camel_case_types
    - empty_constructor_bodies

Check out all the available Dart lint rules.

You can combine the analyzer section and the linter section into a single configuration. Here is an example:

analyzer:
  exclude:
    - test/_data/p4/lib/lib1.dart
linter:
  rules:
    - camel_case_types

For more information, see the docs for customizing static analysis.

Background

The APIs in this package were originally machine generated by a translator and were based on an earlier Java implementation. Several of the API's still look like their Java predecessors rather than clean Dart APIs.

In addition, there is currently no clean distinction between public and internal APIs. We plan to address this issue but doing so will, unfortunately, require a large number of breaking changes. We will try to minimize the pain this causes for our clients, but some pain is inevitable.
