ByteSize is a library that handles how byte sizes are represented and an easy to use interface to convert to other forms of representation also taking locale into consideration.

ByteSize

ByteSize is a null safe library written in Dart language that handles how byte sizes are represented and an easy to use interface to convert to other forms of representation also taking locale into consideration. While adopting the International Electrotechnical Commission (IEC) proposed standard (kibi, mebi, gibi etc.).

Usage

A simple usage example:

import 'package:byte_size/byte_size.dart';

void main() {
  var size = ByteSize.FromKibiBytes(10000);
  print(size.toString('MiB', 3, 'fr_CA')); // 9,766 MiB

  var json = size.toJson();
  print(json);
  // {b: 81920000, B: 10240000.000000000, KiB: 10000.000000000, 
  // MiB: 9.765625000, GiB: 0.009536743, TiB: 0.000009313, PiB: 0.000000009, 
  // KB: 10240.000000000, MB: 10.240000000, GB: 0.010240000, 
  // TB: 0.000010240, PB: 0.000000010}

  var size2 = size.copy();
  print(size2.toString('KiB', 0)); // 10,000 KiB

  var size3 = ByteSize.fromJson(json);
  print(size3.toString()); // 9.77 MiB
  print(size3.toString('', 2, 'en_US', true, false)); // 10.24 MB
}

The toString Function

An empty input string symbol returns the largest whole number value with the unit. Also, negative precision throws the FormatException and if the input string symbol is incorrectly formatted. And, the toString function allows you to choose how you want your ByteSize object string to be display either using the Binary or Decimal representation.

All The Acceptable Input String Symbol Formats

Here are all the acceptable input string symbol formats:

"b" => Bit
"B" => Byte 
"KiB" => KibiByte 
"KB" => KiloByte
"MiB" => MebiByte 
"MB" => MegaByte
"GiB" => GibiByte 
"GB" => GigaByte
"TiB" => TebiByte
"TB" => TeraByte
"PiB" => PebiByte 
"PB" => PetaByte
"EiB" => ExbiByte
"EB" => ExaByte

All symbols between parenthesis are good. Also, be careful about the case-sentivity when it comes to b and B.
