  • Removed internal getReadType, use CompoundAssignmentExpression.
  • Bug fixes: 34699, 43524, 42990.

0.40.3 #

  • Updated the current language version to 2.11.
  • Bug fixes: 43541, 27896, 28066, 28066, 43497, 43478, 28066, 43465, 43462, 43439, 43162, 43397, 43200.

  • Depend on cli_util 0.2.0.

0.39.16 #

  • Added TypeVisitorWithArgument and DartType.acceptWithArgument.
  • Bumped the analyzer's SDK requirement to >=2.7.0, so that extension methods can be used within the analyzer implementation. Previously it was 2.6.0, but there is an issue.

  • Set uri for implicit dart:core import.
  • Add overrideKnownFeaturesAsync() for DartDoc testing.
  • Remove DartSdk.useSummary.
  • Move TypeSystemImpl to src/dart/element/type_system.dart

0.39.11 #

  • Bug fixes: #42007, #42474, #37293, #42385, #36315, #42356, #42274, #42321, #42337, #27387, #34806, #37810, #41072, #42278, #38306, #35036, #23353, #42178, #42216, #42201.

0.39.10 #

  • Restored the default constructor in internal SummaryBuilder, and the featureSet named parameter in build, for build_resolvers compatibility. See #42163.

  • Deprecated DartType.isObject, use DartType.isDartCoreObject for consistency with other similar getters.
  • Deprecated InstanceCreationExpression.staticElement, use constructorName.staticElement instead, like for MethodInvocation.
  • Bug fixes: #34370, #35710, #37552, #38676, #38799, #39644, #41151, #41592, #41614, #41724, #41741, #41797, #41803, #41844, #41997, #42077, #42093, and #42122.

0.39.8 #

  • Deprecated VariableElement.constantValue, it does not guarantee that the value has been computed. Use computeConstantValue() instead.
  • Deprecated the following members of AnalysisOptions: analyzeFunctionBodiesPredicate, disableCacheFlushing, enableLazyAssignmentOperators, generateImplicitErrors, generateSdkErrors, patchPaths, preserveComments, trackCacheDependencies, and resetToDefaults.
  • Bug fixes: #35716, #37048, #40014, #40957, #41479, #41521, #41551, #41555, #41557, #41593, #41603, #41630, #41632, #41645.

0.39.6 #

  • Added Window and DocumentFragment to analyzer's mock SDK. These are required for upcoming changes to the unsafe_html lint.

0.39.5 #

  • Deprecated ClassElement.instantiateToBounds() and FunctionTypeAliasElement.instantiateToBounds(). With the null-safety feature, type arguments derived from type parameter bounds cannot be used as is, and might require erasing nullability, when the element is instantiated from a legacy library. Use TypeSystem.instantiateToBounds2() instead.
  • Deprecated DeclaredVariables.getBool/getInt/getString() and TypeProvider.nullObject. These methods are used internally for constants computation, and should not be used by clients.
  • Deprecated AstFactory.indexExpressionForCascade(). Please use indexExpressionForCascade2 instead.
  • Deprecated AstFactory.indexExpressionForTarget(). Please use indexExpressionForTarget2 instead.
  • Deprecated ClassElement.isOrInheritsProxy and ClassElement.isProxy. The @proxy annotation is deprecated in the langauge, and will be removed.
  • Renamed error code DEFAULT_LIST_CONSTRUCTOR_MISMATCH to DEFAULT_LIST_CONSTRUCTOR. This reflects a spec change: after null safety is enabled, it will be an error to call the default List constructor under all circumstances.
  • Added new warning code: INVALID_NULL_AWARE_OPERATOR.
  • Renamed warning code DEAD_NULL_COALESCE to DEAD_NULL_AWARE_EXPRESSION, to reflect the fact that it applies both to if-null expressions (??) and if-null compound assignment expressions (??=).
  • Fixed bugs 35940, 37122, 38554, 38666, 38791, 38990, 39059, 39597, 39694, 39762, 39791, 39833, 39875, 39876, 39917, 39939, 39976, 40033, 40055, 40057, 40110, 40129, 40221, 40279, 40283, 40287, 40299, 40304, 40316, 40333, 40392, 40394, 40396, 40398, 40413, 40414, 40460, 40482, 40500, 40538, 40546, 40547, 40572, 40578, 40603, 40609, 40677, 40689, 40701, 40704, 40734, 40764, 40837, 40865, 40915, 40931, 40941, 40955, 40956, 40958, 40959, 41019, 41036, 41050, 41095, 41130, and 41180.

  • Deprecated, use element or getDisplayString() instead.
  • Fixed bugs 35108 and 39996.

0.39.3 #

  • Bumped the analyzer's SDK requirement to >=2.6.0, so that extension methods can be used within the analyzer implementation.

Use lookUpGetter2(), lookUpMethod2(), or lookUpSetter2() instead, with concrete or inherited flags as necessary.
  • Deprecated ErrorReporter.reportTypeErrorForNode. Use reportErrorForNode instead.
  • Added new error codes: EXPORT_LEGACY_SYMBOL and DEAD_NULL_COALESCE.
  • Reclassified error codes as compile time errors: BREAK_LABEL_ON_SWITCH_MEMBER, CONTINUE_LABEL_ON_SWITCH, PART_OF_UNNAMED_LIBRARY.
  • Fixed bugs 37116, 38281, 38859, 39524, 39598, 39651, 39667, 39668, 39709, 39711, 39752, 39773, 39848, 39849, and 39880.

0.39.2+1 #

  • Fixed bug #39702.

0.39.1 #

  • Deprecated DartType.substitute2(). Use ClassElement.instantiate() or FunctionTypeAliasElement.instantiate() instead.
  • Deprecated ParameterizedType.instantiate() and InterfaceType.instantiate(). Use ClassElement.instantiate() instead. Using FunctionType.instantiate() is still valid.
  • Deprecated FunctionTypeAliasElement.instantiate2, use instantiate2. In the next version instantiate2 will be removed.

0.39.0 #

  • Removed deprecated DartType.isEquivalentTo.

  • Removed deprecated getter CompilationUnitElement.unit.
  • Removed deprecated method Element.computeDocumentationComment.
  • Removed unused wrapped.dart with WrappedLibraryElement, etc.
  • Removed deprecated 'bestElement', 'bestType', 'propagatedElement', 'propagatedType', etc. Use 'staticElement' and 'staticType' instead.
  • Removed deprecated 'Declaration.element'. Use 'Declaration.declaredElement' instead.
  • Removed deprecated 'Expression.precedence2'. Use 'precedence' instead.
  • Removed ResolutionMap resolutionMap. Use corresponding accessors on AstNode(s) directly to get elements and types.
  • Removed 'InheritanceManager2'. Use 'InheritanceManager3' instead.
  • Removed 'InheritanceManager'. Use 'InheritanceManager3' instead.
  • Removed deprecated methods in DartType: flattenFutures, isAssignableTo, isEquivalentTo, isMoreSpecificThan, isSubtypeOf, isSupertypeOf, isDirectSupertypeOf. Use corresponding methods of TypeSystem instead.
  • Removed deprecated getters for checking a specific annotations on 'Element': isAlwaysThrows, isDeprecated, isFactory, isJS, isOverride, isProtected, isRequired, isVisibleForTesting. Use corresponding hasXyz getters.
  • Removed 'LocalElement.visibleRange'. Visible ranges of local variables and functions can be computed when AST is available.
  • Removed unused LibraryElement.libraryCycle.
  • Removed ElementHandle and ElementResynthesizer.
  • Remove ElementBuilder, DeclarationResolver, DirectiveResolver, TypeParameterBoundsResolver, TypeResolverVisitor, etc. Use ResolutionVisitor instead, it combines all these operations.
  • Removed FunctionTypeAliasElement.instantiate, use instantiate2 for now. In the next version instantiate will be re-introduced with the same signature and semantics as instantiate2, and instantiate2 will be deprecated and removed in the next breaking change version.
  • Stop setting types for identifiers where they are not expressions. Specifically, where a SimpleIdentifier is the name of a declaration, or Identifier is the name of the class in a TypeName.
  • Removed transitional InheritanceManagerBase.
  • Removed deprecated method ArgumentList.correspondingPropagatedParameters. Use ArgumentList.correspondingStaticParameters instead.
  • Removed deprecated getter PrefixElement.importedLibraries. It was never implemented.
  • Removed deprecated getter VariableElement.isPotentiallyMutatedInClosure and VariableElement.isPotentiallyMutatedInScope. Please use the corresponding methods in FunctionBody instead.

0.38.5 #

  • Added the interface PromotableElement, which representing variables that can be type promoted (local variables and parameters, but not fields).
  • Deprecated the boolean AnalysisDriver.useSummary2. Summary1 support has been removed, so clients should assume Summary2 is in use now.
  • Deprecated the constructor argument useDart2jsPaths for SdkLibrariesReader. We now always use Dart2js paths.
  • Bug fixes: #37608, #37708, #37867, #38498, #38565, #38572, #38589, #38641, #38653, #38667, #38695, #38706.

0.38.4 #

  • Bug fixes: #33300, #38484, #38505.

0.38.3 #

  • Deprecated the following codes from StaticWarningCode. Please use the corresponding error codes from CompileTimeErrorCode instead:
  • Bug fixes: #33749, #35985, #37708, #37857, #37858, #37859, #37945, #38022, #38057, #38071, #38091, #38095, #38105, #38113, #38198, #38202, #38203, #38261, #38282, #38365, #38417, #38448, #38449.

0.38.2 #

  • The type of FunctionTypeAlias.declaredElement has been refined to FunctionTypeAliasElement. Since the new type is a refinement of the old one, the only effect on clients should be to make certain casts unnecessary.
  • Deprecated HintCode.INVALID_REQUIRED_PARAM and replaced it with more specific hints, HintCode.INVALID_REQUIRED_NAMED_PARAM, HintCode.INVALID_REQUIRED_OPTIONAL_POSITIONAL_PARAM, and HintCode.INVALID_REQUIRED_POSITIONAL_PARAM to address #36966.
  • Deprecated CompileTimeErrorCode.NOT_ENOUGH_REQUIRED_ARGUMENTS. It has been renamed to CompileTimeErrorCode.NOT_ENOUGH_POSITIONAL_ARGUMENTS.

0.38.1 #

  • LinterVistor support for extension method AST nodes.

0.38.0 #

  • The deprecated method AstFactory.compilationUnit2 has been removed. Clients should switch back to AstFactory.compilationUnit.
  • Removed the deprecated constructor ParsedLibraryResultImpl.tmp and the deprecated method ResolvedLibraryResultImpl.tmp. Please use AnalysisSession.getParsedLibraryByElement and AnalysisSession.getResolvedLibraryByElement instead.
  • Removed MethodElement.getReifiedType.
  • The return type of ClassMemberElement.enclosingElement was changed from ClassElement to Element.

0.37.1+1 #

  • Reverted an unintentional breaking API change (the return type of ClassMemberElement.enclosingElement was changed from ClassElement to Element). This change will be postponed until 0.38.0.

0.37.1 #

  • Added the getters isDartCoreList, isDartCoreMap, isDartCoreNum, isDartCoreSet, isDartCoreSymbol, and isDartCoreObject to DartType.
  • Added the method DartObject.toFunctionValue.
  • Deprecated the isEquivalentTo(DartType) method of DartType. The operator == now correctly considers two types equal if and only if they represent the same type as defined by the spec.
  • Deprecated the isMoreSpecificThan(DartType) method of DartType. Deprecated the isMoreSpecificThan(DartType) method of TypeSystem. Deprecated the isSupertypeOf(DartType) method of TypeSystem. Use TypeSystem.isSubtypeOf(DartType) instead.
  • Deprecated methods flattenFutures, isAssignableTo of DartType. Use TypeSystem.flatten() and TypeSystem.isAssignableTo instead.
  • Deprecated InheritanceManager2, and replaced with InheritanceManager3. InheritanceManager3 returns ExecutableElements, not FunctionType(s).
  • Added the optional parameter path to parseString.
  • Changed TypeSystem.resolveToBound(DartType) implementation to do what its documentation says.
  • This version of the analyzer should contain all the necessary parsing support and AST data structures for the experimental "extension-methods" feature. Further element model improvements needed to support extension methods will be published in 0.38.x.
  • Deprecated InterfaceType.isDirectSupertypeOf. There is no replacement; this method was not intended to be used outside of the analyzer.

0.37.0 #

  • Removed deprecated getter DartType.isUndefined.
  • Removed deprecated class SdkLibrariesReader.
  • Removed deprecated method InstanceCreationExpressionImpl.canBeConst.
  • The AstFactory.compilationUnit method now uses named parameters. Clients that prepared for this change by switching to AstFactory.compilationUnit2 should now switch back to AstFactory.compilationUnit.
  • Removed AstNode.getAncestor. Please use AstNode.thisOrAncestorMatching or AstNode.thisOrAncestorOfType.
  • Removed deprecated getter TypeSystem.isStrong, and its override Dart2TypeSystem.isStrong.
  • Removed the deprecated getter AnalysisError.isStaticOnly and the deprecated setters AnalysisError.isStaticOnly and AnalysisError.offset.
  • Removed the abstract setter in ClassElementImpl, EnumElementImpl, MethodElementImpl, and PropertyAccessorElementImpl. isAbstract should be used instead.
  • Removed methods AstVisitor.ForStatement2, ListLiteral.elements2, SetOrMapLiteral.elements2, AstFactory.forStatement2, and NodeLintRegistry.addForStatement2, as well as class ForStatement2. Use the variants with out the "2" suffix instead.
  • Changed the signature and behavior of parseFile to match parseFile2. Clients that switched to using parseFile2 when parseFile was deprecated should now switch back to parseFile.
  • Removed Parser setters enableControlFlowCollections, enableNonNullable, enableSpreadCollections, and enableTripleShift, and the method configureFeatures. Made the featureSet parameter of the Parser constructor a required parameter.

0.36.4 #

  • Deprecated the isNonNullableUnit parameter of the TypeResolverVisitor constructor. TypeResolverVisitor should now be configured using the featureSet parameter.
  • Refined the return type of the getter TypeParameter.declaredElement. It is always guaranteed to return a TypeParameterElement.
  • Deprecated the abstract setter in ClassElementImpl, EnumElementImpl, MethodElementImpl, and PropertyAccessorElementImpl. isAbstract should be used instead.
  • Changed the way function types are displayed from e.g. (int) -> void to void Function(int). This is more consistent with the syntax of Dart, and it will avoid ambiguities when nullability is added to the type system. This impacts to value returned by FunctionType.displayName and FunctionType.toString and ExecutableElement.toString. Client code might be broken if it depends on the content of the returned value.
  • Introduced the function parseString to the public API. This can be used in place of the deprecated functions parseCompilationUnit and parseDirectives. Note that there is no option to parse only directives, since this functionality is broken anyway (parseDirectives, despite its name, parses the entire compilation unit).
  • Changed the return type of ClassTypeAlias.declaredElement to ClassElement. There is no functional change; it has always returned an instance of ClassElement.
  • Deprecated parseFile. Please use parseFile2 instead--in addition to supporting the same featureSet and throwIfDiagnostics parameters as parseString, it is much more efficient than parseFile.
  • Added more specific deprecation notices to package:analyzer/analyzer.dart to direct clients to suitable replacements.
  • Deprecated the enable flags bogus-disabled and bogus-enabled. Clients should not be relying on the presence of these flags.
  • Deprecated the constructor parameter ConstantEvaluationEngine.forAnalysisDriver, which no longer has any effect.
  • Deprecated ElementImpl.RIGHT_ARROW.

0.36.3 #

  • Deprecated AstFactory.compilationUnit. In a future analyzer release, this method will be changed so that all its parameters are named parameters. Clients wishing to prepare for this should switch to using AstFactory.compilationUnit2.
  • Deprecated Parser setters enableControlFlowCollections, enableNonNullable, enableSpreadCollections, and enableTripleShift, as well as the recently-introduced method configureFeatures. Parsers should now be configured by passing a FeatureSet object to the Parser constructor.
  • Deprecated AnalysisError.isStaticOnly.
  • Deprecated AnalysisError.offset setter.
  • Added method LinterContext.canBeConstConstructor.
  • Bug fixes: #36732, #36775.

0.36.2 #

  • Bug fixes: #36724.

0.36.1 #

  • Deprecated DartType.isUndefined, and now it always returns false.
  • The "UI as code" features (control_flow_collections and spread_collections) are now enabled.
  • Bug fixes: #32918, #36262, #36380, #36439, #36492, #36529, #36576, #36667, #36678, #36691.

0.36.0 #

  • Changed the return type of Expression.precendence to Precedence. Clients that prepared for this change by switching to Expression.precedence2 should now return to using Expression.precedence.
  • AST cleanup related to the "UI as code" feature:
    • Removed the following AST node types:
      • ForEachStatement (use ForStatement instead)
      • MapLiteral and MapLiteral2 (use SetOrMapLiteral instead)

      • visitListLiteral2 (override visitListLiteral instead)
    • Deprecated the visitForStatement2 visit method (use VisitForStatement instead)
    • Removed the following AstFactory methods:
      • mapLiteral and mapLiteral2 (use setOrMapLiteral instead)
      • setLiteral and setLiteral2 (use setOrMapLiteral instead)
      • listLiteral2 (use listLiteral instead)
    • Deprecated AstFactory.forStatement2, and introduced AstFactory.forStatement to replace it
    • Changed the type of the getter ListLiteral.elements to NodeList<CollectionElement>
    • Deprecated ListLiteral.elements2 (use ListLiteral.elements instead)
    • Deprecated SetOrMapLiteral.elements2, and introduced SetOrMapLiteral.elements to replace it
    • Deprecated NodeLintRegistry.addForStatement2 (use NodeLintRegistry.addForStatement instead)
  • Bug fixes: #36158, #36212, #36255

0.35.4 #

  • Deprecated ASTFactory methods that will no longer be available after the control_flow_collections and spread_collections experiments are enabled. The following factory methods are deprecated:
    • mapLiteral and mapLiteral2 (use setOrMapLiteral instead)

  • Bug fixes: #33119, #33241, #35747, #35900, #36048, #36129
  • The analyzer no longer uses package:html (see #35802)

0.35.3 #

  • Further updates to the AST structure for the control_flow_collections and spread_collections experiments. The following AST node types will be deprecated soon:
    • ForEachStatement (use ForStatement2 instead)
    • ForStatement (use ForStatement2 instead)
    • MapLiteral (use SetOrMapLiteral instead)
    • SetLiteral (use SetOrMapLiteral instead)
  • Deprecated Expression.precedence. In analyzer version 0.36.0, its return type will be changed to Precedence. Clients that wish to prepare for the change can switch to Expression.precedence2.
  • Bug fixes: #35908, #35993 (workaround).

0.35.2 #

  • Updated support in the AST structure for the control_flow_collections and spread_collections experiments. The following methods are now deprecated:
    • AstFactory.mapLiteral2 and AstFactory.setLiteral2 (replaced by AstFactory.setOrMapLiteral).
    • AstVisitor.visitListLiteral2 (clients should not need to override this anymore).
    • AstVisitor.visitMapLiteral2 and AstVisitor.visitSetLiteral2 (replaced by AstVisitor.visitSetOrMapLiteral).

  • Bug fixes: #35870, #35922, #35936, #35940,

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.

  • 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.

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.
