asBools method

bool asBools(
  1. List<String> keys, [
  2. bool? defValue
])

解析成bool值

Implementation

bool asBools(List<String> keys, [bool? defValue]) {
  List<String> keyHasValues = [];
  //优先使用返回值就是bool的作为返回值
  for (String key in keys) {
    Object? value = this![key];
    if (value == null) continue;
    if (value is bool) return value;
    keyHasValues.add(key);
  }
  //找不到bool值，兼容其1，或者0，或者字符串作为返回值
  for (String key in keyHasValues) {
    Object? value = this![key];
    if (value == null) continue;
    if (value is int && (value == 1 || value == 0)) {
      return asBool(key);
    }
    if (value is String && (value == "true" || value == "false" || value == '1' || value == '0')) {
      return asBool(key);
    }
  }
  return defValue ?? false;
}
