A BETTER FINDER ATTRIBUTES 6 SERIAL CODE

The new models will also be annotated with and will also get the two new methods from line 12 and 14. Line 5 + 8: For objects inside of our JSON we have to create their representing Model classes for NameModel and PictureModel. Line 3: The annotation tells the build_runner that this class has to be concerned for the generation of a new file and creation of a serialization.

The file will be generated later from the built_runner. Line 1: With the part ‘person_model.g.dart’ we give the PersonModel class the possibility to access the methods inside of the person_model.g.dart file. Dependenciesīefore we can begin to work with the json_serializable package, we have to add first some dependencies into our project. But enough of the words, we want to see some code. We only have to set up our models correctly, annotate them accurately and provide two functions inside. The package works powerfully with the build_runner package and allows us to generate the “fromJSON” and “toJSON” functions, without writing all keys of the JSON. In this article, we will have a closer look at the json_serializable package. There is at the moment not a built-in solution in the Flutter framework, but there are plenty of perfect packages on pub.dev for this problem. Now that we understand the issues with self-written serialisation let’s have a look at generated Flutter JSON Serialization.

Higher maintenance costs especially for larger projects or with changing API´s.

For every new Field that you want to add, delete or modify we have to modify the code in the model.Typos can happen and reduce the stability of your application.There is no setup required, so you can start directly accessing the parameters.No boilerplate surrounding the solution.That would lead to a lot of searches and replacements, and we will lose all IDE supports. Especially if the API changes and we have to create it from scratch. That makes the maintainability pretty hard. Additionally, we come into the trap that if we want to add or remove an attribute, we have to change it all over. As you probably already have seen, we have to write all the key strings into the class and pollute our class with API information. In the code snippet above, we created a new person object that we receive from our API.
