v0.8.1

• Cleanup logging output that duplicates headers provided by
  package:build_runner.

• InvalidGenerationSourceError added an optional element
  parameter to support more helpful error messages.

v0.8.0

• BREAKING removed the deprecated requireLibraryDirective parameter in
  PartBuilder.

• Revivable no longer throws a type error when attempting to revive a
  reference to a top-level function or static-class method. Now is returns a
  reference to that function or method, as expected.

v0.7.6

0.7.6

• TypeChecker now throws an UnresolvedAnnotationException with a more
  detailed exception body (and properties useful for further debugging) instead
  of Could not resolve @null.

v0.7.5+1

• LibraryBuilder and PartBuilder now have a more readable toString(),
  which is useful when emitting a warning or error in a build system. For
  example you may see Generating .g.dart: MyBuilder instead of
  Instance of LibraryBuilder in your build logs.

v0.7.4+2

• BUG FIX: ConstantReader.revive() now properly returns no URL fragment
  when the constant expression is resolved from a top-level or static-field.
  The documentation had said otherwise, and it was impossible to tell the
  difference between a constructor and a field. Now, fields are always in
  the form of accessor = {clazz}.{field} or {topLevelField}.

• Fix file URIs on windows.

v0.7.4+1

• Removed a log.finest with the output source of each generator. This allows
  a verbose option (-v) for tools like bazel or build_runner to be much more
  readable and debuggable. Files are emitted to disk for inspection in any
  case.

v0.7.4

• Added typeNameOf, which is a safe way to get the name of a DartType,
  even when the type is a FunctionType, which has a null name in newer
  versions of the Dart analyzer.

• Added LibraryReader.pathToUrl(Uri|String), which computes the import or
  export path necessary to reach the provided URL from the current library.
  Also added pathToAsset and pathToElement as convenience functions.

• Expanded package:build support to allow version 0.12.0.

v0.7.0

• Breaking changes: See the wiki
  for help upgrading.

  • Generator.generate now operates on a LibraryReader rather than being
    called for every Element within a library. Generators can iterate over
    elements using LibraryReader.allElements. GeneratorForAnnotation will
    continue to call generateForAnnotatedElement repeatedly for each element.
  • GeneratorForAnnotation passes in a ConstantReader for the annotation
    instance rather than re-creating it using mirrors.
  • GeneratorBuilder is replaced with PartBuilder and LibraryBuilder
    depending on whether the output is meant to be included in a part file.
  • Removed JsonSerializable and related classes. These are moved to
    package:json_serializable.
  • Removed lib/builder.dart. Import through source_gen.dart instead.
  • Removed OutputFormatter typedef.

• Add LibraryReader.allElements - a utility to iterate across all Element
  instances contained in Dart library.

• Add LibraryReader.element to get back to the LibraryElement instance.

• Add ConstantReader.objectValue to get back to the DartObject instance.

• Add ConstantReader.peek to read a value that returns null if not found:

// Tries to read the field "token" first, then "_token".
findTokenField(DartObject o) {
  final reader = new ConstantReader(o);
  final token = o.peek('token') ?? o.read('_token');
}

• Add throwOnUnresolved optional parameter to TypeChecker.annotationsOf,
  TypeChecker.annotationsOfExact, TypeChecker.firstAnnotationOf, and
  TypeChecker.firstAnnotationOfExact. Setting this to false will enable you
  to check for matching annotations with incomplete type information (at your
  own risk).
• Builder logs now log the primary inputs AssetId instead of the library,
  which is more useful for tracking down the actual files.

v0.6.1+1

• Added spanForElement; returns a SourceSpan for an analyzer Element.
• Logs a warning to the console when a GeneratorBuilder outputs a part file
  for a given input, but that input does not define part 'name.g.dart';.

v0.6.0

• Breaking change: TypeChecker#annotationsOf|firstAnnotationOf now
  returns annotations that are assignable to the TypeChecker's type. As a
  result we've added #annotationsOfExact|firstAnnotationOfExact which has the
  old behavior for precise checks.

• TypeChecker#annotations...-methods now throw a StateError if one or more
  annotations on an element are not resolvable. This is usually a sign of a
  mispelling, missing import, or missing dependency.

• Added TypeChecker.any, which delegates to multiple other TypeChecker
  implementations when making a type check.
