<div>It is easy to make errors when writing the serialization code, so it is generally recommended to use the json_serializable package by the Dart Team. However, you can read about the pros and cons of the different methods here.</div><div></div><div></div><div></div><div></div><div></div><div>flutter download json file</div><div></div><div>Download: https://t.co/FGd7TH1cC1 </div><div></div><div></div><div>Note: Conditional JSON parsing logic can be written with if/else statements or the switch syntax as shown above. Another alternative is to use the Freezed package, which can be configured to generate the JSON parsing code using json_serializable. For more info, read: FromJson/ToJson.</div><div></div><div></div><div>JSON serialization with code generation means having an external librarygenerate the encoding boilerplate for you. After some initial setup,you run a file watcher that generates the code from your model classes.For example, json_serializable and built_value are thesekinds of libraries.</div><div></div><div></div><div>Unfortunately, jsonDecode() returns a dynamic, meaningthat you do not know the types of the values until runtime. With this approach,you lose most of the statically typed language features: type safety,autocompletion and most importantly, compile-time exceptions. Your code willbecome instantly more error-prone.</div><div></div><div></div><div></div><div></div><div></div><div></div><div>info Choosing a library: You might have noticed two Flutter Favorite packages on pub.dev that generate JSON serialization code, json_serializable and built_value. How do you choose between these packages? The json_serializable package allows you to make regular classes serializable by using annotations, whereas the built_value package provides a higher-level way of defining immutable value classes that can also be serialized to JSON.</div><div></div><div></div><div>First, add json_serializable to your pubspec.yaml file as a dependency and also as a dev_dependency. We also need to add a reference to build_runner, as json_serializable uses build_runner to create the functionality for us.</div><div></div><div></div><div>package:json_serializable</div><div></div><div>An easy-to-use code generation package.When you add some metadata annotationsand use the builder provided by this package,the Dart build system generates serialization and deserialization code for you.</div><div></div><div> df19127ead</div>
