data serializer
data_serializer #
Portable Dart package to handle data serialization/deserialization efficiently,
including a dynamic BytesBuffer to read/write data.
API Documentation #
See the API Documentation for a full list of functions, classes and extension.
Usage #
import 'package:data_serializer/data_serializer.dart';
void main() {
// Dynamic bytes buffer with initial capacity of 16 bytes.
var buffer = BytesBuffer(16);
// Write a unsigned int of 32 bits:
buffer.writeInt32(0x10203040);
// Write a `String` encoded using UTF-8:
buffer.writeString('Hello!');
// Write a unsigned int of 64 bits:
buffer.writeUint64(9223372036854775807);
// Write a data block (prefixed by 4 bytes for he data length).
var dataBlock = [110, 120, 130, 140, 150, 160].toUint8List();
buffer.writeBlock32(dataBlock);
// Write all bytes:
buffer.writeAll([210, 220]);
// The current length of the buffer, expanded automatically:
print('length: ${buffer.length}');
// Change the current position cursor to `0`:
buffer.seek(0);
// Read a 32 bits int:
var n32 = buffer.readUint32();
print('n32: 0x${n32.toHex32()}');
// Reads a `String` decoding from UTF-8:
var s = buffer.readString();
print('s: $s');
// Read a 64 bits int:
var n64 = buffer.readUint64();
print('n64: $n64');
// The current buffer position:
print('position: ${buffer.position}');
// Read a data block:
var dataBlock2 = buffer.readBlock32();
print('dataBlock2: $dataBlock2');
// The position after read the data block:
print('position: ${buffer.position}');
// The remaining bytes in the buffer:
var tailBytes = buffer.readRemainingBytes();
print('tailBytes: $tailBytes');

Browser/JavaScript compatibility #
All the operations are tested to be compatible with JavaScript.
Note that JS only supports 53-bits integers. To avoid any issue serializing 64-bits integers,
try to use BigInt serialization, or ensure that you are bellow the 53-bits range.
See the class DataSerializerPlatform if you need runtime information
about integers support.
Test Coverage #
This package aims to always have a high test coverage percentage, over 95%.
With that the package can be a reliable tool to support your important projects.
