Description:

datapacker

Serialize data into binary format.
Features #

Upto 30% length reduction compared to JSON.

var dataPacker = DataPacker(
dateAsString: false,
);

Usage #
const payload = {
'sender': {
'name': 'Alice'
},
'message': 'Hi',
'sent_at': DateTime.now(),
'is_delivered': false
};

var datapackerSerialized = dataPacker.serialize(payload);
var datapackerDeserialized = dataPacker.deserialize(datapackerSerialized);
copied to clipboard
JSON Comparison #
var jsonSerialized = jsonEncode(payload);
var jsonDeserialized = jsonDecode(jsonSerialized);

print(datapackerSerialized.length); // <---- 75 bytes
//(Dates preprocessed to ISO-8601, Uint8List preprocessed to Base64)
print(jsonSerialized.length); // <---- 102 bytes
