'BoolToStringProcessor' and 'StringToBoolProcessor' is useful to convert Uri.queryParameters to Json

[droplet-js]

class BoolToStringProcessor implements FieldProcessor<bool, String> {
  const BoolToStringProcessor();

  @override
  bool deserialize(String value) {
    return value == true.toString();
  }

  @override
  String serialize(bool value) {
    return value.toString();
  }
}

class StringToBoolProcessor implements FieldProcessor<String, bool> {
  const StringToBoolProcessor();

  @override
  String deserialize(bool value) {
    return value.toString();
  }

  @override
  bool serialize(String value) {
    return value == true.toString();
  }
}

const FieldProcessor<bool, String> boolToStringProcessor =
    BoolToStringProcessor();
const FieldProcessor<String, bool> stringToBoolProcessor =
    StringToBoolProcessor();
