标签: built-value

当我运行时flutter pub run build_runner build --delete-conflicting-outputs，我收到此错误：

Deprecated. Use `dart run` instead.

built_value生成.g.dart代码，但文档没有给出任何提示，我们是否应该将它们添加到我们的 git 存储库中。

我认为我们应该，所以克隆我们的 repo 的开发人员可以启动并运行，而不必重新生成代码......但有些人说永远不应该提交生成的代码，那么，有什么建议built_value？

在我连接到服务器的应用程序中，返回此输出：

"usertags": {
    "in": [
        {

        }
    ]
},

那in是 dart 关键字，我不知道如何逃避它以从中获取数据，但出现此错误：

错误：需要一个班级成员。

abstract class BuiltUserTags implements Built<BuiltUserTags, BuiltUserTagsBuilder> {

  BuiltList<BuiltIn>    get   in;

  BuiltUserTags._();

  factory BuiltUserTags([updates(BuiltUserTagsBuilder b)]) = _$BuiltUserTags;

  static Serializer<BuiltUserTags> get serializer => _$builtUserTagsSerializer;
}

我正在使用一个对其 json 属性使用 lowercase_with_underscores 命名约定的 api：

{
  "user_id": 0,
  "full_name": ""
}

我的built_value 类是：

abstract class User implements Built<User, UserBuilder> {
  //...
  @BuiltValueField(wireName: "user_id")
  int get userId;

  @BuiltValueField(wireName: "full_name")
  String get fullName;
  //...
}

有没有办法更改所有built_value类的built_value序列化器命名约定，以便它自动将my_propertyjson分配给myPropertybuilt_value模型，而不是用于BuiltValueField(wireName: "my_property")每个属性？

尝试使用内置值生成器时出错

这是我得到的错误。

我用来运行内置值生成器的类

import 'package:built_value/built_value.dart';

part 'src/json_parsing.g.dart';

abstract class Article implements Built<Article, ArticleBuilder> {
  Article._();
  factory Article([void Function(ArticleBuilder) updates]) = _$Article;
}
