Description:

analyzer

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.
Who uses this library? #
Many tools embed this library, such as:

dart format - a formatter for Dart code
dart doc - a documentation generator for Dart code
Dart Analysis Server - a stateful server that supports IDEs and editors

Post issues and feature requests at https://github.com/dart-lang/sdk/issues.
These will be triaged according to the analyzer triage priorities.
Questions and discussions are welcome at the
Dart Analyzer Discussion Group.
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.
