Flutter 如何在WidgetRef引用外部的函数中使用Riverpod刷新数据

我正在用户/配置文件屏幕中使用Ffltter Riverpod从Api获取数据.

这是我用来构造用户界面的代码

Widget build(BuildContext context, WidgetRef ref) {
    final profileData = ref.watch(profileDataProvider);
    return SafeArea(
      child: Scaffold(
        appBar: topBar,
        drawer: const Menu(),
        body: SingleChildScrollView(
          child: SizedBox(
            child: Column(
              children: [
                profileData.when(
                  data: (data) {
                    String image = data.data.userProfile.picture.thumbnail;
                    if (profileData.isRefreshing) {
                      return const CircularProgressIndicator.adaptive();
                    }
                    return Column(
                      children: [
                        const SizedBox(height: 20),
                        Stack(
                          clipBehavior: Clip.none,
                          children: <Widget>[
                            Container(
                              width: 200.0,
                              height: 200.0,
                              decoration: BoxDecoration(
                                shape: BoxShape.circle,
                                image: DecorationImage(
                                  image: CachedNetworkImageProvider(image),
                                ),
                              ),
                            ),
                            Positioned(
                              bottom: 5,
                              right: 5,
                              child: IconButton(
                                onPressed: () {
                                  showModalBottomOptions(context);
                                },
                                icon: Icon(
                                  Icons.add_a_photo_outlined,
                                  color: ColorConstants.iconTextFieldColor,
                                  size: 40,
                                ),
                              ),
                            )
                          ],
                        ),
                        const SizedBox(height: 20),
                        const Divider(color: Colors.grey),
                        Text(
                          '${data.data.userProfile.firstName} ${data.data.userProfile.lastName}',
                        ),
                        Text(data.data.userProfile.email),
                        Text(data.data.userProfile.mobile),
                      ],
                    );
                  },
                  error: ((error, stackTrace) {
                    return Text(error.toString());
                  }),
                  loading: CircularProgressIndicator.adaptive,
                ),
                const SizedBox(height: 20),
                const Divider(color: Colors.grey),
                const Text('OS Type (Andriod, iOS, Chrome)'),
                const SizedBox(height: 20),
                const Text('OS Version'),
                const SizedBox(height: 20),
                const Text('DeviceId'),
                const SizedBox(height: 20),
                const Divider(color: Colors.grey),
                OutlinedButton(
                  onPressed: () {
                    Navigator.push(
                        context,
                        MaterialPageRoute(
                          builder: (context) => const ChangePassword(),
                        ));
                  },
                  child: Text(
                    'Change Password',
                    style: TextStyle(
                      color: ColorConstants.buttonTextColor,
                      fontSize: TextSize.textButtonSize,
                    ),
                  ),
                ),
              ],
            ),
          ),
        ),
      ),
    );
  } 

函数showMoalBottomOptions显示了两个选项(Camera和Gallery)来 Select 图像，然后我有一个函数可以获取图像并将其上传到服务器.

应用程序工作，但我面临的问题是，图片上传后，我不知道如何在UI中显示新的图像，因为showModalBottomOptions函数超出了构建(BuildContext上下文，WidgetRef ref)我无法访问它.

我如何再次调用Api来刷新图像并向用户显示？

我没有包括showMoalBottomOptions以使这篇文章更简短，如果需要，我可以发布它.

谢谢你抽出时间来，我真的很感激！
