Release Notes

dart-lang/sdk (analyzer)

v6.8.0

• Add AnalysisContextCollection.dispose(). It must be invoked at the end.
• Deprecated ContextLocator and ContextBuilder. Use AnalysisContextCollection instead.

v6.7.0

• Deprecated File.createSource(), it violates levels of abstraction. You can get Source instances from AnalysisResults.
• Deprecated unused static members of AnalysisError.

v6.6.0

• Stop exporting src/file_system/file_system.dart from file_system/file_system.dart.
• Deprecated package:analyzer/src/source/source_resource.dart, import package:analyzer/source/file_source.dart instead.
• Deprecated exports from package:analyzer/src/source/source.dart, import package:analyzer/source/source.dart instead.

v6.5.2

• Updated constraints macros: '>=0.1.2-0 <0.1.3'.

v6.5.1

• Updated constraints macros: '>=0.1.1-0 <0.1.2'.

v6.5.0

• Deprecated LibraryElement.toLegacyTypeIfOptOut.
• Deprecated LibraryElement.toLegacyElementIfOptOut.
• Deprecated LibraryElement.isNonNullableByDefault.
• Deprecated InterfaceElement.lookUpGetter, InterfaceElement.lookUpMethod, and InterfaceElement.lookUpSetter.
• Fixed GeneralizingAstVisitor.visitNamedType to invoke visitTypeAnnotation.
• Deprecated PropertyInducingElement get variable in PropertyAccessorElement, use PropertyInducingElement? get variable2 instead. The reason for this is that when the property accessor is an augmentation without the corresponding declaration, there is no corresponding variable.
• Deprecated ExtensionDeclaration.onKeyword and extendedType. Use ExtensionOnClause? get onClause instead. Extension augmentations are not allowed to have onClause.
• Deprecated OnClause, use MixinOnClause instead.
• Support new meta annotation: @doNotSubmit.
• Support new meta annotation: @mustBeConst.
• Support new meta TargetKinds: constructor, directive, enumValue, and typeParameter.
• Fix for accessing constants from extension type, when import prefixed.
• Deprecated AstNode.getProperty and AstNode.setProperty. Clients who need the ability to add arbitrary decorations to AST nodes can achieve the same effect using Dart's built-in Expando class.

v6.4.1

• Patch for crash in ffi_verifier.

v6.3.0

• Updated the current language version to 3.3.
• Removed generated ConstantEvaluator.

v6.2.0

• Heap usage improvements.

v6.1.0

• Added InstanceElement, a super-interface for InterfaceElement and ExtensionElement.
• Added TypeSystem.greatestLowerBound.

v6.0.0

• Remove deprecated declaredElement2 from AST.
• Remove deprecated element2 from AST.
• Remove deprecated name2 from AST.
• Remove deprecated FunctionBody.isPotentiallyMutatedInClosure.
