Global Unlock

Demonstrates how to unlock the Chilkat API with a global (Bundle) purchased unlock code, or with a 30-day trial unlock code. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // The Chilkat API can be unlocked for a fully-functional 30-day trial by passing any
  // string to the UnlockBundle method.  A program can unlock once at the start. Once unlocked,
  // all subsequently instantiated objects are created in the unlocked state. 
  // 
  // <b>After licensing Chilkat, replace the "Anything for 30-day trial" with the purchased unlock code.</b>
  // To verify the purchased unlock code was recognized, examine the contents of the LastErrorText
  // property after unlocking.  For example:
  final glob = CkGlobal();
  try {
    glob.unlockBundle('Anything for 30-day trial');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final status = glob.unlockStatus;
  if (status == 2) {
    print('Unlocked using purchased unlock code.');
  } else {
    print('Unlocked in trial mode.');
  }

  // The LastErrorText can be examined in the success case to see if it was unlocked in
  // trial more, or with a purchased unlock code.
  print(glob.lastErrorText);
}
