analyzer library

Static analysis and AST inspection utilities for Dart code tools.

Classes

AnalysisContextHelper: Helper for initializing analyzer AnalysisContextCollection instances and safely resolving compilation units.
CommentDirectiveParser: Generic token-based suppression parser for // <tool>:ignore and // <tool>:ignore_for_file comment suppression directives.
WildcardPattern: Zero-dependency wildcard matching supporting * and ? patterns.

extractNodeName(AstNode node) → String?: Extracts a string name from an AST node safely.
getTopLevelElement(Element elem) → Element?: Finds the enclosing top-level element for a given element by climbing the enclosing hierarchy until reaching the library element or null.
hasAnnotation(AnnotatedNode node, String annotationName) → bool: Checks if an AnnotatedNode contains an annotation with the given annotationName (e.g. 'visibleForTesting', 'pragma', 'Native').
hasAnyAnnotation(AnnotatedNode node, Iterable<String> annotationNames) → bool: Checks if an AnnotatedNode has any of the given annotationNames.
isExcludedPath(String relativePath) → bool: Whether relativePath sits inside a directory that should never be scanned (.dart_tool, .git, or build output).
isNativeOrEntryPoint(AnnotatedNode node) → bool: Checks if an AST node has native or runtime entrypoint annotations (@Native, @native, or explicit entrypoint @pragma like @pragma('vm:entry-point') or @pragma('vm:isolate-unsendable')).
isTestSupportDeclaration(AnnotatedNode node, [String? name]) → bool: Checks if an element or AST node has test support annotations or conventions.
