convert

• Require Dart 3.4
• Add chunked decoding support (startChunkedConversion) for CodePage encodings.
• Upper-cast the return type of the decoder from List<int> to Uint8List.
• Move to dart-lang/core monorepo.

• Require Dart 2.18
• Fix a number of comment references.

• Add a fixed-pattern DateTime formatter. See #210 in package:intl.

• Fix bug in CodePage class. See issue #47.

• Dependency clean-up.

• Stable null safety release.
• Added CodePage class for single-byte Encoding implementations.

• Fixed a DDC compilation regression for consumers using the Dart 1.x SDK that was introduced in 2.1.0.

• Added an IdentityCodec<T> which implements Codec<T,T> for use as default value for in functions accepting an optional Codec as parameter.

• Set max SDK version to <3.0.0, and adjust other dependencies.

• PercentEncoder no longer encodes digits. This follows the specified behavior.

Note: No new APIs have been added in 2.0.0. Packages that would use 2.0.0 as a lower bound should use 1.0.0 instead—for example, convert: ">=1.0.0 <3.0.0".

• HexDecoder, HexEncoder, PercentDecoder, and PercentEncoder no longer extend ChunkedConverter.

• Fix all strong-mode warnings.

• Add AccumulatorSink, ByteAccumulatorSink, and StringAccumulatorSink classes for providing synchronous access to the output of chunked converters.

• Small improvement in percent decoder efficiency.
