0.9.1 #
-
The result of
ConstantReader.revive()
now returns aRevivable
that assumes access to a private class, constructor, or function instead ofnull
where possible. This allows generators that usepart
files to still use this functionality and allows generators that use separate libraries to emit more actionable error messages (i.e."cannot use private class _X"
). -
Revivable.isPrivate
now returnstrue
when the underlying class was public but the constructor was private, or theRevivable
was pointing to a top-level or static private field or method. Previously it was onlytrue
when referencing a private class.
0.9.0+1 #
- Fix
LibraryReader.classElements
to return classes from parts, if they exist, as well as from the defining library file.
0.9.0 #
- Introduce
SharedPartBuilder
for creating part files that can be merged with a newCombiningBuilder
. Note thatCombiningBuilder
only outputs.g.dart
files. - Breaking
PartBuilder
now requires ageneratedExtensions
argument. The value should not be.g.dart
. To produce.g.dart
files please use theSharedPartBuilder
.
0.8.3+1 #
- Allow using non-dev Dart 2 SDK.
0.8.3 #
GeneratorForAnnotation
generateForAnnotatedElement
now allow multiple return values when implementations return anIterable
orStream
.- Values from
generateForAnnotatedElement
have whitespace trimmed.null
and empty values are ignored. - Duplicate values are collapsed into a single values. This allows emitting shared, top-level members without naming collisions.
0.8.2 #
-
Simplification to the output of generator names in header sections.
-
Update handling of whitespace in generator outputs.
- If the output from a generator has wrapping whitespace, it is trimmed.
- If the output from a generator is empty or whitespace-only, it is ignored.
- These changes will likely have no effect on output, unless you customize the code formatter.
0.8.1+3 #
- More redundant new lines elimination.
0.8.1+2 #
- Eliminate redundant new lines in the core builder. These were almost removed by running the default formatter. Now the unformatted code more closely matches the default output.
0.8.1+1 #
- Support
package:analyzer
0.32.0
.
0.8.1 #
-
Cleanup logging output that duplicates headers provided by
package:build_runner
. -
InvalidGenerationSourceError
added an optionalelement
parameter to support more helpful error messages.
0.8.0 #
-
BREAKING removed the deprecated
requireLibraryDirective
parameter inPartBuilder
. -
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.
0.7.6 #
TypeChecker
now throws anUnresolvedAnnotationException
with a more detailed exception body (and properties useful for further debugging) instead ofCould not resolve @null
.
0.7.5+1 #
LibraryBuilder
andPartBuilder
now have a more readabletoString()
, which is useful when emitting a warning or error in a build system. For example you may seeGenerating .g.dart: MyBuilder
instead ofInstance of LibraryBuilder
in your build logs.
0.7.5 #
-
The
PartBuilder
constructor parameterrequireLibraryDirective
now defaults tofalse
. It will be removed in0.8.0
. -
Require at least Dart
2.0.0-dev.19.0
.
0.7.4+3 #
- Support the latest
analyzer
package.
0.7.4+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.
0.7.4+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.
0.7.4 #
-
Added
typeNameOf
, which is a safe way to get the name of aDartType
, even when the type is aFunctionType
, which has anull
name in newer versions of the Dart analyzer. -
Added
LibraryReader.pathToUrl(Uri|String)
, which computes theimport
orexport
path necessary to reach the provided URL from the current library. Also addedpathToAsset
andpathToElement
as convenience functions. -
Expanded
package:build
support to allow version0.12.0
.
0.7.3 #
- Allow null and empty outputs form
GeneratorForAnnotation
.
0.7.2+1 #
- Allow
package:build
version 0.11.0
0.7.2 #
- Support an optional
header
argument toPartBuilder
andLibraryBuilder
.
0.7.1 #
Generator{ForAnnotation}
#
- Return type of
generate{ForAnnotatedElement}
is nowFutureOr<String>
.
LibraryReader
#
- Added
annotatedElements
to return all elements annotated with something. - Added
classElements
getter for returning allclass
-es in a library.
TypeChecker
#
- Added
hasAnnotationOf
andhasAnnotationOfExact
.
ConstantReader
#
- Added
isAny
(for consistency, but deprecated) andisLiteral
. - Added
literalValue
as an alias for the now deprecatedanyValue
. - Allow
literalValue
to returnnull
if the value is actuallynull
. - Fixed a bug where a
Symbol
would return as aString
foranyValue
. - Fixed a bug where a
List
andMap
were not considered literals.
0.7.0 #
-
Breaking changes: See the wiki for help upgrading.
Generator.generate
now operates on aLibraryReader
rather than being called for everyElement
within a library. Generators can iterate over elements usingLibraryReader.allElements
.GeneratorForAnnotation
will continue to callgenerateForAnnotatedElement
repeatedly for each element.GeneratorForAnnotation
passes in aConstantReader
for the annotation instance rather than re-creating it using mirrors.GeneratorBuilder
is replaced withPartBuilder
andLibraryBuilder
depending on whether the output is meant to be included in apart
file.- Removed
JsonSerializable
and related classes. These are moved topackage:json_serializable
. - Removed
lib/builder.dart
. Import throughsource_gen.dart
instead. - Removed
OutputFormatter
typedef.
-
Add
LibraryReader.allElements
- a utility to iterate across allElement
instances contained in Dart library. -
Add
LibraryReader.element
to get back to theLibraryElement
instance. -
Add
ConstantReader.objectValue
to get back to theDartObject
instance. -
Add
ConstantReader.peek
to read a value that returnsnull
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 toTypeChecker.annotationsOf
,TypeChecker.annotationsOfExact
,TypeChecker.firstAnnotationOf
, andTypeChecker.firstAnnotationOfExact
. Setting this tofalse
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 thelibrary
, which is more useful for tracking down the actual files.
0.6.1+1 #
- Tighten constraint on
source_span
.
0.6.1 #
- Added
spanForElement
; returns aSourceSpan
for an analyzerElement
. - Logs a warning to the console when a
GeneratorBuilder
outputs a part file for a given input, but that input does not definepart 'name.g.dart';
.
0.6.0 #
- Breaking change:
TypeChecker#annotationsOf|firstAnnotationOf
now returns annotations that are assignable to theTypeChecker
's type. As a result we've added#annotationsOfExact|firstAnnotationOfExact
which has the old behavior for precise checks. TypeChecker#annotations...
-methods now throw aStateError
if one or more annotations on an element are not resolvable. This is usually a sign of a misspelling, missing import, or missing dependency.- Added
TypeChecker.any
, which delegates to multiple otherTypeChecker
implementations when making a type check.
0.5.10+1 #
- Update minimum
analyzer
package to0.29.10
.
0.5.10 #
- Bug fixes:
- Do not fail when "library" is omitted but nothing would be output.
- Do not fail on extensions that don't end in ".dart" (valid use case).
0.5.9 #
-
Update the minimum Dart SDK to
1.22.1
. -
Deprecated
builder.dart
: importsource_gen.dart
instead. -
Added
TypeChecker
, a high-level API for performing static type checks:import 'package:analyzer/dart/element/type.dart'; import 'package:source_gen/source_gen.dart'; void checkType(DartType dartType) { // Checks compared to runtime type `SomeClass`. print(const TypeChecker.forRuntime(SomeClass).isExactlyType(dartType)); // Checks compared to a known Url/Symbol: const TypeChecker.forUrl('package:foo/foo.dart#SomeClass'); // Checks compared to another resolved `DartType`: const TypeChecker.forStatic(anotherDartType); }
-
Failing to add a
library
directive to a library that is being used as a generator target that generates partial files (part of
) is now an explicit error that gives a hint on how to name and fix your library:> Could not find library identifier so a "part of" cannot be built. > > Consider adding the following to your source file: > > "library foo.bar;"
In Dart SDK
>=1.25.0
this can be relaxed aspart of
can refer to a path. To opt-in,GeneratorBuilder
now has a new flag,requireLibraryDirective
. Set it tofalse
, and also set yoursdk
constraint appropriately:sdk: '>=1.25.0 <2.0.0'
-
Added
LibraryReader
, a utility class forLibraryElement
that exposes high-level APIs, includingfindType
, which traversesexport
directives for publicly exported types. For example, to findGenerator
frompackage:source_gen/source_gen.dart
:void example(LibraryElement pkgSourceGen) { var library = new LibraryReader(pkgSourceGen); // Instead of pkgSourceGen.getType('Generator'), which is null. library.findType('Generator'); }
-
Added
ConstantReader
, a high-level API for reading from constant (static) values from Dart source code (usually represented byDartObject
from theanalyzer
package):abstract class ConstantReader { factory ConstantReader(DartObject object) => ... // Other methods and properties also exist. /// Reads[ field] from the constant as another constant value. ConstantReader read(String field); /// Reads [field] from the constant as a boolean. /// /// If the resulting value is `null`, uses [defaultTo] if defined. bool readBool(String field, {bool defaultTo()}); /// Reads [field] from the constant as an int. /// /// If the resulting value is `null`, uses [defaultTo] if defined. int readInt(String field, {int defaultTo()}); /// Reads [field] from the constant as a string. /// /// If the resulting value is `null`, uses [defaultTo] if defined. String readString(String field, {String defaultTo()}); }

Breaking: Switch to the
build
package for runningGenerator
s. This means that the top levelbuild
andgenerate
functions are no longer available, and have been replaced by the top levelbuild
,watch
, andserve
functions from thebuild
package, and theGeneratorBuilder
class. Seetool/build.dart
,tool/watch.dart
, andtool/phases.dart
for usage.- Note that the
build
package is experimental, and likely to change.
- Note that the
-
Breaking: The build package provides an abstraction for reading/writing files via the
BuildStep
class, and that is now also provided toGenerator#generate
andGeneratorForAnnotation#generateForAnnotatedElement
as a second argument. -
Timestamps are no longer included in generated code.
-
There is no longer a need to specify the files related to an individual generator via
AssociatedFileSet
. Simply use theBuildStep
instance to read and write files and thebuild
package will track any files you read in and run incremental rebuilds as necessary.
