check method

bool check(Object? data)

Check if the condition is satisfied by passing data.

When DynamicMap is passed, the value for key is checked.

If [List]' is passed, it checks whether or not the elements of the list satisfy the condition, and returns true` if one of them satisfies the condition.

All other values are checked to see if they satisfy the condition themselves, regardless of key.

Implementation

bool check(Object? data) {
  if (data == null) {
    return false;
  }
  if (data is DynamicMap) {
    if (key.isEmpty) {
      return false;
    }
    if (!data.containsKey(key)) {
      return false;
    }
    return _check(data[key]);
  } else if (data is List) {
    return data.any((element) => check(element));
  } else {
    return _check(data);
  }
}
