We use Json Serializable [ https://flutter.dev/docs/development/data-and-backend/json#code-generation ] package build tool to generate model from Json to Class object.
Required packages:
To create model, create a file with data as following with needed field.
lib/core/models/story_model.dart ```dart import ‘package:spooky/core/base/base_model.dart’; import ‘package:copy_with_extension/copy_with_extension.dart’; import ‘package:json_annotation/json_annotation.dart’;
part ‘story_model.g.dart’;
@CopyWith() @JsonSerializable() class StoryModel extends BaseModel { final int? id; final String? name; …
StoryModel({ this.id, this.name, … });
@override Map<String, dynamic> toJson() => _$StoryModelToJson(this); factory StoryModel.fromJson(Map<String, dynamic> json) => _$StoryModelFromJson(json); }
### 2. Generating
Run following command to generate `*.g.dart` file for your model. Additionally, It will also generate other models `.g.dart` in case they have changes.
```s
fvm flutter pub run build_runner build --delete-conflicting-outputs
We use snack case by default, so we might no longer use @JsonKey(name: "recommendation_id").
// From this
@JsonKey(name: "recommendation_id")
String? recommendationId;
// To just this:
String? recommendationId;
We can customize & override current behaviour in build.yaml.
