我有两个页面：HomePage和DetailsPage以及关联的GetxControllers。

主页：

class HomePage extends GetView<HomeController> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('HomePage')),
      body: Container(
        child: Obx(
          () => ListView.builder(
            itemCount: controller.task.length,
            itemBuilder: (context, index) {
              return ListTile(
                leading: Text('${index + 1}'),
                title: Text(controller.task[index]["name"]),
                onTap: () {
                  Get.to(
                    DetailsPage(),
                    arguments: controller.task[index]["name"],
                  );
                },
              );
            },
          ),
        ),
      ),
    );
  }
}

家庭控制器：

class HomeController extends GetxController {
  final TaskRepository repository;
  HomeController({@required this.repository}) : assert(repository != null);

  final _task …

我正在尝试发出put请求以使用GetConnect更新用户配置文件。用户个人资料采用一些普通的 JSON 字段和一个用于个人资料图片的MultipartFile 。

这是我的ProfileProvider类：

class ProfileProvider extends GetConnect {
 Future<ProfileModel> updateProfile({
  String name,
  String email,
  String address,
  File avatar,
 }) async {

 final headers = {
  "Authorization": "Bearer $token",
  "Content-Type": "application/json",
  "Accept": "application/json",
};

String fileName = avatar.path.split("/").last;
final form = FormData({
  "name": name,
  "email": email,
  "address": address,
  "avatar": MultipartFile(avatar, filename: fileName),
});

final response = await put(url, form, headers: headers);

if (response.statusCode == 200) {
  final profileModel = ProfileModel.fromJson(response.bodyString);

  return profileModel;
   } …
