JsonMessageCodec<T> constructor

const JsonMessageCodec<T>({
  1. required Map<String, dynamic>? toJson(
    1. T
    ),
  2. required T? fromJson(
    1. Map<String, dynamic>
    ),
  3. Object? toEncodable(
    1. Object? nonEncodable
    )?,
  4. Object? reviver(
    1. Object? key,
    2. Object? value
    )?,
})

Creates a JsonMessageCodec.

toJson is a function that converts an object of type T to a Map<String, dynamic>. fromJson is a function that creates an object of type T from a Map<String, dynamic>. toEncodable is an optional function passed to jsonEncode to handle objects that are not directly encodable to JSON. reviver is an optional function passed to jsonDecode to transform decoded values.

Implementation

const JsonMessageCodec({
  required Map<String, dynamic>? Function(T) toJson,
  required T? Function(Map<String, dynamic>) fromJson,
  Object? Function(Object? nonEncodable)? toEncodable,
  Object? Function(Object? key, Object? value)? reviver,
})  : _toJson = toJson,
      _fromJson = fromJson,
      _toEncodable = toEncodable,
      _reviver = reviver;
