toString method
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() {
return "{application_id: '${getApplicationId()}', pg: '$pg', method: '$method', methods: ${getMethodList()}, name: '$name', price: $price, tax_free: $taxFree, order_id: '$orderId', use_order_id: $useOrderId, params: ${getParamsStringAndroid()}, account_expire_at: '$accountExpireAt', show_agree_window: $showAgreeWindow, user_token: '$userToken', extra: ${extra.toString()}, user_info: ${user.toString()}, items: ${getItems()}}";
}
