Body
ByteConversionSink
The ByteConversionSink provides an interface for converters to efficiently transmit byte data.

This class provides a base-class for converters that need to accept byte inputs.
ByteStream
A stream of chunks of bytes representing a single piece of data.
ChunkedConversionSink<T>
A ChunkedConversionSink is used to transmit data more efficiently between two converters during chunked conversions.
Client
The interface for HTTP clients that take care of maintaining persistent connections across multiple requests to the same server.
ClosableStringSink
A ClosableStringSink extends the StringSink interface by adding a close method.
Codec<S, T>
A Codec encodes and (if supported) decodes data.
Converter<S, T>

JsonCodec
A JsonCodec encodes JSON objects to strings and decodes strings to JSON objects.
JsonDecoder
This class parses JSON strings and builds the corresponding objects.
JsonEncoder
This class converts JSON objects to strings.
JsonUtf8Encoder
Encoder that encodes a single object as a UTF-8 encoded JSON string.
Latin1Codec
A Latin1Codec encodes strings to ISO Latin-1 (aka ISO-8859-1) bytes and decodes Latin-1 bytes to strings.
Latin1Decoder
This class converts Latin-1 bytes (lists of unsigned 8-bit integers) to a string.
Latin1Encoder
This class converts strings of only ISO Latin-1 characters to bytes.
LineSplitter
A StreamTransformer that splits a String into individual lines.
MediaType
A class representing an HTTP media type, as used in Accept and Content-Type headers.

Post
PrettyLogger
Put
Query
Request
An HTTP request where the entire request body is known in advance.
RequestInterceptor
Response<T>
ResponseInterceptor
StreamedRequest
An HTTP request where the request body is sent asynchronously after the connection has been established and the headers have been sent.
StreamedResponse
An HTTP response where the response body is received asynchronously after the headers have been received.
StringConversionSink
This class provides an interface for converters to efficiently transmit String data.
StringConversionSinkBase
This class provides a base-class for converters that need to accept String inputs.
StringConversionSinkMixin
This class provides a mixin for converters that need to accept String inputs.
Utf8Codec
A Utf8Codec encodes strings to utf-8 code units (bytes) and decodes UTF-8 code units to strings.
Utf8Decoder
This class converts UTF-8 code units (lists of unsigned 8-bit integers) to a string.
Utf8Encoder
This class converts strings to their UTF-8 code units (a list of unsigned 8-bit integers).
