Constructors

AnalysisError(Source source, int offset, int length, ErrorCode errorCode, [List<Object?>? arguments, List<DiagnosticMessage> contextMessages = const []])

Initialize a newly created analysis error. The error is associated with the given source and is located at the given offset with the given length. The error will have the given errorCode and the list of arguments will be used to complete the message and correction. If any contextMessages are provided, they will be recorded with the error.

AnalysisError.forValues(Source source, int offset, int length, ErrorCode errorCode, String message, String? _correctionMessage, {List<DiagnosticMessage> contextMessages = const []})

Initialize a newly created analysis error with given values.

AnalysisError.withNamedArguments(Source source, int offset, int length, ErrorCode errorCode, Map<String, dynamic> arguments, {List<DiagnosticMessage> contextMessages = const []})

Initialize a newly created analysis error. The error is associated with the given source and is located at the given offset with the given length. The error will have the given errorCode and the map of arguments will be used to complete the message and correction. If any contextMessages are provided, they will be recorded with the error.

Properties

contextMessages → List<DiagnosticMessage>

A list of messages that provide context for understanding the problem being reported. The list will be empty if there are no such messages.

Static Properties

ERROR_CODE_COMPARATOR ↔ Comparator<AnalysisError>

A Comparator that sorts error codes first by their severity (errors first, warnings second), and then by the error code type.

getter/setter pair

FILE_COMPARATOR ↔ Comparator<AnalysisError>

A Comparator that sorts by the name of the file that the AnalysisError was found.

getter/setter pair

Static Methods

mergeLists(List<List<AnalysisError>> errorLists) → List<AnalysisError>

Merge all of the errors in the lists in the given list of errorLists into a single list of errors.

Constants

NO_ERRORS → const List<AnalysisError>

An empty array of errors used when no errors are expected.
