Purpose

This package is for easy conversion to rawdata(List<int>) to be sent to BLE devices, etc.
The types supported by this package are utf8, int8/16/32/64, uint8/16/32/64.
it is based on Swift(iOS) int type.

How to Use

• String to utf-8

  // encode
  const String sampleStr = "sample";
  final List<int> strData = BLEDataConverter.str.stringToUtf8(randomStr);

  print(strData) // [115, 97, 109, 112, 108, 101]
  
  // decode
  final String decodeStr = BLEDataConverter.str.stringFromUtf8(strData)

  print(decodeStr) // "sample"

• int to int64 byte data

  // encode
  final int i64Max = 9223372036854775807;
  final List<int> value = BLEDataConverter.i64.intToBytes(i64Max);

  print(value); // [255, 255, 255, 255, 255, 255, 255, 127]

  // decode
  final int decode = BLEDataConverter.i64.bytesToInt(value);

  print(decode); // 9223372036854775807
