ask_sync method

bool? ask_sync({ List<String> positive = const [], })

Prompts a user for a yes or no answer.

The following are considered yes responses:

• yes
• y
• sure
• ok
• yep
• yeah
• true
• yerp

You can add more to the list of positive responses using the positive argument.

The input will be changed to lowercase and then checked.

Implementation

bool? ask_sync({
  final List<String> positive = const [],
}) {
  final answer = prompt_sync();
  if (answer == null) {
    // ignore: avoid_returning_null
    return null;
  } else {
    return DC_YES_RESPONSES.contains(answer.toLowerCase()) || positive.contains(message.toLowerCase());
  }
}
