reflectable

Released as reflectable version 5.2.3

• Update dependency to use analyzer ^13.0.0.

Released as reflectable version 5.2.2

• Update the language version to 3.12.

Released as version 5.2.1

• Fix bugs #354 and #325.

Released as version 5.2.0

• Upgrade reflectable to use analyzer ^10.0.0 and lints ^6.0.0.

• Upgrade reflectable to use version ^8.0.0 of the analyzer and version ^4.0.0 of build.

• Add an example that does not rely on code generation, basically just a recommendation to look at reflectable_builder for a real example.

• Breaking change: Split the code generator off of the package reflectable. This code generator must henceforth be obtained from the package reflectable_builder. The point is that this can be a dev_dependency. This also implies that build.yaml must specify the reflectable code generator as reflectable_builder: rather than just reflectable:.

• Use language version 3.9. In particular, use the 3.9 style of formatting.

• Use language version 3.7.
• Migrate reflectable to use analyzer version ^7.0.0 (which removes the dependency on _macros, which doesn't exist any more).
• This includes a small part of the migration work needed in order to use the new element model in the analyzer (Element2, for now).
• Lots of reformatting (creates a big diff).

• Use language version 3.6.
• Use newer versions of build_runner_core (^8.0.0) and dart_style (^3.0.0), to enable the new formatting style.
• Ignore deprecated member use because build_runner is not yet ready for the new Element model.
• Add support for suppression of warnings via environment variables. The environment variable has prefix REFLECTABLE_SUPPRESS_... and then UPPER_CASE of the WarningKind. For example, export REFLECTABLE_SUPPRESS_BAD_METADATA=yes will suppress the badMetadata warning.
• Reformat the implementation to use the new style.
• Introduce support for specifying the language version used by the formatter by setting REFLECTABLE_FORMATTER_LANGUAGE_VERSION to a value of the form [0-9]+\\.[0-9]+.
• Added information to the design document in doc about the supported environment variables.

• Revert analyzer dependency to 6.8.0 and lints to 5.0.0 due to macro related version resolution conflict. Undo some changes that are required for analyzer 6.11.0, but which are errors with 6.8.0.

• Fix bug 291 (such that metadata on enum values can be obtained).
• Update dependencies to use analyzer 6.11.0 and lints 5.1.0.
• Change the implementation to use ..._obvious_local_variable_types lints.
• Update the [capability design document][1] slightly.

• Reintroduce support for newer versions of the analyzer (6.7.0 and up).

• Lower the upper bound for the analyzer to avoid a complaint that we should import a library that doesn't exist with the analyzer when using the lower bound. Import the older library that does exist.

• Downgrade analyzer to 6.5.0, to avoid version conflict involving macros and _macros (that we can't do anything about from here).

• Update dependencies to use sdk 3.4.0 and analyzer 6.7.0.

• Update dependencies to use analyzer 6.4.0.

• Remove legacy tests (they cannot be executed when using a version of Dart which will be released soon).

• Use an upper bound of 4.0.0 for the SDK constraint, preparing for said release.

• Change the computation of the Uri of a library mirror such that it is taken from the AssetId of the library, when possible. This should be helpful in situations where the Uri is used to find the actual file. This is technically a breaking change, but we do not consider it to be a breaking change in practice, because the Uri's provided in previous versions were essentially meaningless strings. They were just known to be distinct for distinct libraries, and that property also holds with this change.

  For documentation about how these URIs are generated, please see https://pub.dev/documentation/build/latest/build/AssetId/uri.html and https://pub.dev/documentation/build/latest/build/AssetId-class.html .

  For documentation about package URIs, please see https://api.dart.dev/stable/2.19.2/dart-isolate/Isolate/packageConfig.html and, for example, https://pub.dev/packages/package_config.

• Resolve bug #300. Expressions of the form f<T> denoting a generic instantiation of a function (that is: the result of passing the type argument T to the generic function f, yielding a non-generic function) was not supported; this version supports it.

• Change code generation such that null safe programs do not give rise to a language version comment in the generated code. Previously, such programs would have // @dart = 2.12 in the generated library, but this causes newer features to be unavailable in the generated code. As before, programs which are not fully null safe will have a generated library that contains // @dart = 2.9.

• Change handling of 'dart:...' libraries, to handle new behavior by build_resolvers 2.1.0: 'dart:html' wasn't reported before by resolver.libraries, but is now included. To preserve existing behavior (and avoid generating code that imports 'dart:html'), this update removes 'dart:html' from the set of libraries that are considered "importable" by generated code.

• Update reflectable to use (and require) analyzer 5.2.0. This is a substantial update, because several analyzer members in the analyzer have been deprecated.

• Update reflectable to use (and require) analyzer 5.0.0. This is a substantial update, because several analyzer members in the analyzer have been deprecated, and some replacements have different return types.
• Breaking change: The analyzer now reports that the 'mixin' of a 'mixin application class' (e.g., class B = A with M1, M2;) is the class itself (i.e., B), and the last mixin (M2) is obtained as mirror.superclass.mixin. Previously the same mixin would be obtained with mirror.mixin. This is actually a more faithful model than the one used previously, so the new behavior is also used by reflectable. (In particular, if we have class B2 = A with M1, M2; then B == B2 is not true, which implies that the mixin application class works like a regular class declaration with an empty body, e.g., class B = A with M1, M2; works like class B extends A with M1, M2 {}, where mirror.superclass.mixin is the natural way to obtain a mirror of M2). This is a breaking change, but it only affects usages where there is a dependency on the exact superclass structure, and it seems likely that this only happens rarely: we may well traverse all supertypes or all superclasses, but we are not likely to do things like "go to the 5th superclass, find the mixin, and check that it has a foo method".

• Perform a minimal migration to use analyzer 4.6.0.

• Add support for checking whether a TypeMirror is reflecting on a nullable or non-nullable type.
• Update dependencies to use analyzer ^4.2.0, lints ^2.0.0.

• Correct bug reported as #267 (null was generated in a case where the expression had to have type int).
• Change code generation such that no invocations of generative constructors of enums are generated (such that it works with 'enhanced-enums').

• Change analysis_options.yaml such that we get the same linting locally and on pub.dev. Update many libraries and tests to conform to the currently recommended lints.

• Update reflectable to require analyzer ^3.2.0; adjust several locations in the code where null is handled, but analyzer methods will now return a non-null value. Optimize several capability related getters by caching the result.

• Update reflectable to require analyzer ^3.0.0 (currently using 3.1.0), and to replace the package pedantic by the package lints.

• Fix the bug reported as #255.

• Update dependencies: analyzer: ^2.0.0
• Fix issue #253.

• Migrate the code generator. The reflectable package is hereby fully migrated to null safety.
• Update the following dependencies: build_config ^1.0.0, build_runner: ^2.0.1, build_runner_core: ^7.0.0.

• Use dart_style ^2.0.0.

• Support null safety in a stable version of reflectable.
• Change minimum SDK constraint to 2.12.0.
• Use analyzer ^1.1.0; build ^2.0.0; build_resolvers ^2.0.0; glob ^2.0.0; logging ^1.0.0; package_config ^2.0.0.
• Bug fix: Handle types of the form T* in some extra cases.

• Enable analyzer version 0.41.2.
• Change code generation to use new Resolver.astNodeFor method, eliminating the InconsistentAnalysisException workaround in most cases.
• Prevent unnecessary code generation for inputs named *.vm_test.*, *.node_test.*, or *.browser_test.*, to reduce code generation time.

• Migrate the generated code and its dependencies to null safety.
• Remove bestEffortReflectedType, hasBestEffortReflectedType, deprecated since version 0.5.0.
• Change the return type of ObjectMirror.delegate from dynamic to Object?, for consistency with several methods named invoke....

• Change build.yaml to ensure that 'lib/main.dart' will again be considered an entry point for code generation.
• Update dependencies to include analyzer 0.40.5, 0.40.6, 0.41.0, 0.41.1.
• Re-fixing issue #198, cf. google/built_value.dart issue #941.

• Update dependencies to include analyzer 0.40.4, with 0.40.3 as lower bound because of a breaking change.

• Update dependencies to support analyzers up to version 0.40.3.

• Resolve #198 (InconsistentAnalysisException), based on workaround from dart-lang/build#2634. Also widen the analyzer version constraint to include all 0.39 versions published at this point.

• Update dependencies. In particular, analyzer can now be 0.39.10. Handle issue with sync* functions, cf. issue #210.

• Eliminate dependency on package package_resolver (which is deprecated).

• Introduce support for the type void as a reified type.

• Generate code which will not cause implementation_imports diagnostics.

• Fix a bug concerned with the ordering of named parameters in a constructor declaration.
• Update reflectable to use package analyzer version <0.40.0.
• Ensure that generated code is lint free with package pedantic 1.9.0.
• Make reflectable itself lint free with package pedantic 1.9.0.

• Restricting analyzer version to <= 0.39.3, because 0.39.3 contains a breaking change in the parameter list of a constructor.

• Update reflectable to work with analyzer 0.39.4.

• Adjust implementation to satisfy 'pedantic' lints. The generated code does this as well, except that some const modifiers are generated even though they could be omitted (an // ignore_for_file comment is generated such that the linter does not complain about this). Upgrade dependencies to allow using analyzer 0.38.5, and current versions of many other packages.

• Code generator rewritten in order to work with changes in the analyzer APIs, enabling the use of analyzer version 0.37.0 (and newer versions of many other packages), which addresses issue #173. See issue #180 about missing support for two features: This affects code in platform libraries (that is, libraries imported with 'dart:...' except 'dart:ui'). If a declaration in a platform library has metadata, a query for this metadata using DeclarationMirror.metadata will return null. Also, if a constructor in a platform library has a parameter with a default value, and that parameter is omitted in a reflective invocation, the value passed will be null rather than the declared value. This is a bug, but it is blocked on getting access to AST nodes in platform libraries from the resolver provided by build.

• Follow-up bug fix related to #170: Corrected ParameterMirror.defaultValue for initializing formals.

• Bug fix #170: Default values for initializing formals are now included when generating function literals for newInstance.

• Updated dependency to allow using source_span 1.5.3.

• Lint fixes (e.g., T x; rather than T x = null;).

• Updated dependency to allow using analyzer 0.34.

• Fix version conflict #153: Updated version constraints on analyzer, build, build_runner, and test. Ported reflectable_builder.dart to work with new build API.

• Corrected the email address listed in pubspec.yaml for Dart Team.

• Bug fix #132: We used to generate terms like prefix2.di.inject in order to denote a top level declaration named inject, but that's an error because di is an import prefix from client code. We now strip off such prefixes (yielding prefix2.inject) in the cases reported in issue #132.

• Adjusts an implementation class (MixinApplication) such that a compile-time error occurring with analyzer 0.32.5 is avoided.

• Enhancement of the support for reflection on type arguments, covering cases where a type annotation is a parameterized type where all type arguments are resolved statically (e.g., List<int> f();). We (still) do not support cases where one or more type arguments are or contain type variables from an enclosing function or class (like the type of the formal parameter to List.addAll: List<E>), and with such type arguments a dynamic error is raised if an attempt is made to access it. Similarly, we (still) do not support extracting the value of the actual type arguments for an instance of a generic class (e.g., for a given list, we cannot obtain the precise value of the actual type argument; we can test things like myList is List<num> and myList is List<String> without reflection at all, but that only reveals an upper bound, not the precise value of the type argument, and we cannot get that precise value without support for some additional primitives).

• The build.yaml file in reflectable was adjusted such that a much larger set of files are included for code generation. This means that we will err on the side of generating code for too many files rather than too few, but this choice seems to be more user-friendly. Developers who get irritated about seeing warnings like "This reflector does not match anything" (which is a likely outcome for code generation applied to some arbitrary library which is not an entry point) can then add a build.yaml file specifying more precisely which libraries to generate code for.

• Null error bug fix.
