Provides runtime support for a Dart implementation of protobufs.

Typically one do not need to import this library–only libraries
generated by the protoc plugin import this library directly.

If your library or application uses generated protobuf libraries, add this
library as a dependency.

## Changelog
## 0.7.2

* Fix hashing for PbList.

## 0.7.1

* Fix type in PbList.fold() for Dart 2.
* Small performance tweaks for DDC.

## 0.7.0

* Added fast getters for common types.
* Only pass index instead of both tag and index to accessors.
* Delegate more methods to underlying list in PbList.
* Small fixes for Dart 2.0.

## 0.6.0

* Added enumValues to FieldInfo. Fixes #63.
* Small performance optimization when deserializing repeated messages
  from JSON.
* Type annotations for strong mode.

## 0.5.5

* Use real generic syntax instead of comment-based.
* Support v2 dev SDKs.

## 0.5.4

* Unknown enum values are ignored when parsing JSON, instead of throwing an
  exception.

## 0.5.3+2

* Resolved a strong-mode error.

## 0.5.3+1

* Performance: Avoid excessive cloning in merge.
* Performance: Use code patterns that dart2js handles better.

## 0.5.3

* fix zigzag function so all coded buffer reader tests work on dart2js.

## 0.5.2

* make PbMixin constructor public for use within protoc plugin.

## 0.5.1+5

* Revert previous change because it causes strong mode type error
in the generated code. We will revisit this in a new version of
mixin support.

## 0.5.1+4

* Use a more refined implementation of `Map` in `PbMapMixin`

## 0.5.1+3

* Performance: eliminate some dynamic calls.

## 0.5.1+2

* Bugfix: remove dependency on `pkg/crypto` for real.

## 0.5.1+1

* Require at least Dart SDK 1.13.

* Removed dependency on `pkg/crypto`.

## 0.5.1

* Experimental support for strong mode.
* Fixed an issue with GeneratedMessage operator== and Map mixins
* Added declaration of GeneratedMessage clone method

## 0.5.0+1

* Support the latest version of package `fixnum`.

## 0.5.0
 * Reorganized internals to improve performance. We now store
   field values in a list instead of a map. Private properties
   and methods are all moved to the \_FieldSet class. There
   are new entry points for generated getters, hazzers, and
   setters. Improved JSON decoding performance.
 * Dropped compatibility with .pb.dart files before 0.4.2
   by removing internal constants from GeneratedMessage. Also,
   protoc plugins before 0.5.0 won't work.

## 0.4.2
 * Renamed FieldType to PbFieldType.

## 0.4.1 - DO NOT USE
 * added FieldType class. It turned out that FieldType is a
   commonly used name, even in .proto files. This is renamed to
   PbFieldType in 0.4.2.
 * Added support for observing field changes.
   For now, this can only be enabled by using a mixin to override
   the eventPlugin getter.
 * Removed optional third parameter from setField().
   It was only intended for internal use, and could be used to
   defeat type checks on fields.
 * clearExtension() removes the value and extension in all cases.
   (Before, the extension would be kept and the list cleared
   for repeated fields.)
 * Upcoming: clearField() will require its argument to be a known
   tag number (which could be an extension). For now, this is only
   enforced when a mixin provides an eventPlugin.

## 0.4.0
 * Add ReadonlyMessageMixin. The generated message classes use this to
   for the default values of message fields.

## 0.3.11
 * Add meta.dart which declares reserved names for the plugin.

## 0.3.10
 * Add GeneratedService and ProtobufClient interfaces.

## 0.3.9
 * Add experimental mixins_meta library
 * Add experimental PbMapMixin class (in a separate library).
 * Fix bug where ExtensionRegistry would not be used for nested messages.

## 0.3.7
 * More docs.

## 0.3.6
 * Added mergeFromMap() and writeToJsonMap()
 * Fixed an analyzer warning.

## 0.3.5+3
 * Bugfix for `setRange()`: Do not assume Iterable has a `sublist()` method.

## 0.3.5+2
 * Simplify some types used in is checks and correct PbList to match the
 * signature of the List setRange method.

## 0.3.5+1

 * Bugfix for incorrect decoding of protobuf messages: Uint8List views with
   non-zero offsets were handled incorrectly.

## 0.3.5

 * Allow constants as field initial values as well as creation thunks to reduce
   generated code size.

 * Improve the performance of reading a protobuf buffer.

 * Fixed truncation error in least significant bits with large Int64 constants.
