FlJsonMessageCodec:

#FlJsonMessageCodec is an #FlMessageCodec that implements the encodes FlValue to/from JSON. This codec encodes and decodes FlValue of type FL_VALUE_TYPE_NULL, FL_VALUE_TYPE_BOOL, FL_VALUE_TYPE_INT, FL_VALUE_TYPE_FLOAT, FL_VALUE_TYPE_STRING, FL_VALUE_TYPE_UINT8_LIST, FL_VALUE_TYPE_INT32_LIST, FL_VALUE_TYPE_INT64_LIST, FL_VALUE_TYPE_FLOAT_LIST, FL_VALUE_TYPE_LIST, and FL_VALUE_TYPE_MAP.

#FlJsonMessageCodec matches the JSONMessageCodec class in the Flutter services library. fl_json_message_codec_new:

Creates an #FlJsonMessageCodec.

Returns: a new #FlJsonMessageCodec.
