Conversion utilities package

This package contains encoders and decoders for converting between different data representations. It's the external counterpart of the dart:convert core library, and contains less-central APIs and APIs that need more flexible versioning.


  • 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.
