toString method

String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

String toString() {
  List<String> parts = [];

  void addPart(String key, dynamic value, {bool? isOriginal}) {
    if (value != null) {
      if(isOriginal == true) {
        parts.add("$key: $value");
      } else {
        // String formattedValue = value is String ? "'${value.replaceAll("'", "\\'")}'" : value.toString(
        String formattedValue = value is String ? "'${value.queryReplace()}'" : value.toString();
        parts.add("$key: $formattedValue");
      }
    }
  }

  addPart('application_id', getApplicationId());
  addPart('pg', pg);
  addPart('method', getMethodValue(), isOriginal: true);
  addPart('order_name', orderName);
  addPart('price', price);
  addPart('tax_free', taxFree);
  addPart('deposit_price', depositPrice);

  addPart('order_id', orderId);
  addPart('subscription_id', subscriptionId);
  addPart('authentication_id', authenticationId);
  addPart('metadata', getMetadataStringAndroid(), isOriginal: true);

  addPart('user_token', userToken);
  addPart('extra', extra.toString(), isOriginal: true);
  addPart('user', user.toString(), isOriginal: true);
  addPart('items', getItems(), isOriginal: true);

  addPart('use_terms', widgetUseTerms);
  addPart('sandbox', widgetSandbox);
  // addPart('widget_sandbox', widgetSandbox);
  addPart('widget_key', widgetKey);
  if(widgetKey != null) addPart("widget", 1);
  addPart('oopay', widgetOopay?.toJson(), isOriginal: true);
  addPart('currency', currency);
  addPart('wallet_id', _widgetWalletId);
  addPart('terms', getSelectTermsValue(), isOriginal: true);
  // addPart('select_terms', getSelectTermsValue(), isOriginal: true);

  return "{${parts.join(", ")}}";
