Dart's built_value library, how to generate the serializer file in flutter?

Question

• I've added the built_value dependency.
• I've created a file serializers.dart with the serializer field.
• I've converted one of my data classes to the required format.

How do I actually build the project to generate the serializers.g.dart file?

Thanks

Solution

In recent versions you need a @SerializersFor() annotation

See also the example project https://github.com/google/built_value.dart/blob/master/chat_example/lib/data_model/serializers.dart

library serializers;

import 'package:built_collection/built_collection.dart';
import 'package:built_value/serializer.dart';
import 'package:chat_example/data_model/data_model.dart';

part 'serializers.g.dart';

/// Collection of generated serializers for the built_value chat example.
@SerializersFor(const [
  Chat,
  ListUsers,
  ListUsersResponse,
  Login,
  LoginResponse,
  ShowChat,
  Status,
  Welcome,
])
final Serializers serializers = _$serializers;

And remember you need to run your build.dart/watch.dart by hand--it's not part of the flutter build process. e.g. run dart tool/build.dart. See the example projects for an example build.dart/watch.dart.

@DavidMorgan yes that's what I was missing
