This package contains an experimental API for dealing with JSON encoded data.
This is not an officially supported Google product.
JSON is a text format which can represent a general "JSON structure". There are many ways to generate JSON text and convert JSON text to native data structures in most languages.
A JSON structure is either a primitive value: a number, a string, a boolean or a null value, or it is a composite value. The composite value is either a JSON array, a seqeunce of JSON structures, or a JSON object, a sequence of pairs of string keys and JSON structure values.
Dart typically represents the JSON structure using List and Map objects
for the composite values and num, String, bool and Null values for
the primitive values.
This package provides various ways to operate on a JSON structure without necessarily creating intermediate Dart lists or maps.
The JsonReader provides a pull based approach to investigating and
deconstructing a JSON structure, whether it's represented as a string,
bytes which are the UTF-8 encoding of such a string, or by Dart object
structures.
The JsonSink provides a push based approach to building
a JSON structure. This can be used to create JSON source or structures
from other kinds of values.
The JsonBuilder functions provide a composable way to convert a
JSON structure to another kind of value.
