length property

int get length

The total length of the request body, in bytes. This is calculated from fields and files and cannot be set manually.

Implementation

int get length {
  var length = 0;
  fields.forEach((entry) {
    length += '--'.length +
        _BOUNDARY_LENGTH +
        '\r\n'.length +
        utf8.encode(_headerForField(entry.key, entry.value)).length +
        utf8.encode(entry.value).length +
        '\r\n'.length;
  });

  for (var file in files) {
    length += '--'.length +
        _BOUNDARY_LENGTH +
        '\r\n'.length +
        utf8.encode(_headerForFile(file)).length +
        file.value.length +
        '\r\n'.length;
  }

  return length + '--'.length + _BOUNDARY_LENGTH + '--\r\n'.length;
}
