Analyzer for Dart #

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.

Configuring the analyzer #

Both 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:

    - 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:

    - 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:

    - test/_data/p4/lib/lib1.dart
    - camel_case_types

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

Background #

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.

0.35.1 #

  • The new "set literals" language feature is now enabled by default.
  • The dev_dependency analysis_tool was created so that clients do not have to depend on code that is used internally in the analyzer at development time.
  • The InheritanceManager class is now deprecated. The new InheritanceManager2 class now supports accessing inherited interface/class maps.
  • Added quick assists to support set literals.
  • Added the ability for linter tests to drive the analyzer using custom analysis options.
  • Updated support in the AST structure for the control_flow_collections and spread_collections experiments. The new AST structures are still in development.
  • Bug fixes: #34437, #35127, #35141, #35306, #35621.

0.35.0 #

  • Added support in the AST structure for the control_flow_collections and spread_collections experiments. This includes adding new visitor methods to AstVisitor, which will need to be implemented by any classes that implement AstVisitor directly. Concrete implementations were added to other visitor classes (such as RecursiveAstVisitor) so that clients that extend those other classes will not be impacted.
  • Removed EMPTY_LIST constants. Please use const <...>[] instead.
  • Disabled support for the task model. Please use the new AnalysisSession API.
  • Removed StrongTypeSystemImpl. Please use Dart2TypeSystem instead.
  • Made ERROR the default severity for StaticWarningCode. We no longer need to promote warnings to errors in "strong mode" because strong mode is the only mode.
  • Added exact type analysis for set literals (#35742).
  • Bug fixes: #35305, #35750.

0.34.3 #

  • Non-breaking AST changes in support for the control_flow_collections and spread_collections experiments. Clients who wish to begin adding support for these experiments can depend on this release of the analyzer and begin writing visit methods. The visit methods won't be added to the AstVisitor base class until 0.35.0.
  • Bug fixes: #35551, #35708, #35723.

0.34.2 #

  • Removed support for the @checked annotation. Please use the covariant keyword instead (#28797).
  • Did additional work on the new set_literals and constant_update_2018 features.
  • Began adding a string representation of initializer expressions to summaries (#35418).
  • Added a pub aware workspace so that pub packages can be handled properly.
  • Added logging in an effort to track down #35551.
  • Removed the unused hint code INVALID_ASSIGNMENT.
  • Added a hint enforcing the contract of @literal: NON_CONST_CALL_TO_LITERAL_CONSTRUCTOR.
  • Added a hint INVALID_LITERAL_ANNOTATION (#34259).
  • Fixed handling of @immutable on mixins.
  • Did work on @sealed annotation for classes and mixins.
  • Bug fixes: #25860, #29394, #33930, #35090, #35441, #35458, #35467, #35548.

0.34.1 #

  • Added logic to report a hint if a deprecated lint is specified in the user's analysis_options.yaml file, or if a lint is specified twice.
  • Added a note to the UriResolver documentation alerting clients of an upcoming breaking change.
  • Improved parser recovery.
  • Speculative work on fine-grained dependency tracking (not yet enabled).
  • Initial support for new language features set_literals and constant_update_2018.
  • Early speculative work on non-nullable types.
  • Added AnalysisDriver.resetUriResolution().
  • Deprecated TypeSystem.isStrong.
  • Added WorkspacePackage classes, for determining whether two files are in the "same package."
  • Added a public API for the TypeSystem class.
  • Bug fixes: #33946, #35151, #35223, #35241, #35438.

0.34.0 #

  • Support for declarations-casts has been removed and the implicit-casts option now has the combined semantics of both options. This means that users that disable implicit-casts might now see errors that were not previously being reported.
  • Minor changes to the AnalysisSession and AnalysisDriver APIs to make it easier for clients to transition away from using the task model.
  • Minor changes to the linter API to make it easier for lint rules to define their own lint codes.
  • Add a version of getAncestor that matches by type without a closure.
  • Add an AST structure for set literals.
  • Bug fixes: #35162, #35230, #34733, #34741, #33553, #35090, #32815, #34387, #34495, #35043, #33553, #34906, #34489.
