validate method
Matches the code and executes the callback if code is a match.
Implementation
Future<bool> validate(
BuildContext context, {
required List<KonamiCodeInput> inputHistory,
}) async {
if (inputHistory.length < codes.length) {
return false;
}
for (int index = 0; index < codes.length; index++) {
final code = codes[index];
final historyIndex = inputHistory.length - codes.length + index;
final swipe = inputHistory[historyIndex];
if (code != swipe) {
return false;
}
}
await onMatch(context);
return true;
}
