formatBytes method

String formatBytes([
  1. int decimals = 1
]) 
print(99025.formatBytes()); // 96.7 KB

Implementation

String formatBytes([int decimals = 1]) {
  int bytes = int.parse(toString());
  if (bytes <= 0) return "0 B";
  const suffixes = ["B", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB"];
  var i = (log(bytes) / log(1024)).floor();
  return '${(bytes / pow(1024, i)).toStringAsFixed(decimals)} ${suffixes[i]}';
}
