Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // Note: This example requires Chilkat v9.5.0.92 or greater.
  // (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)
  final sb = CkStringBuilder();

  // Load the eReceipt JSON into a StringBuilder object.
  try {
    sb.loadFile('qa_data/itida/EReceipt_ex.json', 'utf-8');
  } on ChilkatException {
    print('Failed to load input file.');
    return;
  }

  // Convert the contents of sb to the ITIDA canonical form.
  // Always pass utf-8 for the 2nd arg.
  sb.encode('itida', 'utf-8');

  // Get the lowercase hex encoded SHA256 hash of the canonicalized JSON
  // (always use utf-8)
  final uuid = sb.getHash('sha256', 'hex_lower', 'utf-8');
  print('eInvoicing UUID = $uuid');
