This package provides a low-level library that performs static analysis of Dart code. It is useful for tool integration and embedding.
End-users should use the dartanalyzer 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.
dartanalyzer 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
dartanalyzer 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 the analyzer's strong mode:
analyzer: strong-mode: true
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
Many tools embed this library, such as:

The APIs in this package are, quite frankly, a mess at the moment. They 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 (or worse) rather than clean Dart API’s.
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.
