类型“ double”不是类型“ int”的子类型

Question

我正在尝试通过id（来自tmdb）获取详细信息

  Stream<DetailsTv> getDetailsTv(int id) async* {
    http.Response response =
        await http.get('$mainUrl/tv/$id?api_key=$apiKey&language=en-US');
    yield DetailsTv.fromJson(jsonDecode(response.body));
  }

StreamBuilder<DetailsTv>(
          stream: stream.getDetailsTv(id),
          builder: (context, snapshot) {
            if (snapshot.hasData) {
              return Container(
                child: Text(snapshot.data.name),
              );
            }
            else if (snapshot.hasError) {
                    return Center(
                      child: Text(snapshot.error.toString()),
                    );
                  } else {
              return Center(
                child: CircularProgressIndicator(),
              );
            }
          }),

但是我得到这个错误 类型“ double”不是类型“ int”的子类型 但是id是int

Answer 1

stream.getDetailsTv(int.parse(id.toString())) 确保将id转换为int
