toJson property

bool? toJson
final

Whether to generate a toJson or not

If null, picks up the default values from the project's build.yaml.

If that value is null too, will be inferred based on whether the Freezed class has a fromJson constructor`, such that

@freezed
class Example with _$Example {
  factory Example(int a) = _Example;

  factory Example.fromJson(Map<String, Object?> json) => _$ExampleFromJson(json);
}

generates a toJson.

On the other hand, changing fromJson(Map json) => _$ExampleFromJson(json) to no-longer use => and instead use { return } will disable the generation of toJson,

@freezed
class Example with _$Example {
  factory Example(int a) = _Example;

  factory Example.fromJson(Map<String, Object?> json) {
    // Will not generate a _$ExampleFromJson class as we are using `{ return }`
    return {...};
  }
}

Implementation

final bool? toJson;
