toPostJson method
Converts the body data model to a JSON object for a POST request.
This method should be implemented by subclasses to convert their specific data to a JSON object. It should only include properties that need to be sent in a POST request.
Implementation
@override
Map<String, dynamic>? toPostJson() {
final Map<String, dynamic> data = <String, dynamic>{};
data["name"] = name;
data["percentage"] = percentage;
data["storeId"] = storeId;
return data;
}
