如何解决Get.back() getx
返回时更新数据的问题。
过渡方案：
ProfileView -> FollowPersonalView -> ProfilePublicController -> FollowPersonalView -> ProfilePublicController -> FollowPersonalView
当从 ProfilePublicController -> FollowPersonalView 开始时，我以某种方式设法更新了数据，尽管我不完全确定我做对了。
但是当你返回FollowingPersonalView -> ProfilePublicController -> FollowPersonalView时，最后阶段的数据没有更新
从逻辑上讲，它们应该从 ProfileView 中提取
配置文件控制器
class ProfileController extends GetxController
with SingleGetTickerProviderMixin {
var isLoading = true.obs;
var countPage = 0.obs;
var profileData = UserModel().obs;
TabController tabController;
@override
void onInit() {
tabController = new TabController(length: 3,vsync: this);
Future.wait([
_apiGetProfile(),]);
super.onInit();
}
Future _apiGetProfile() async {
try {
isLoading(true);
var profile = await RemoteServices.fetchProfile();
if (profile != null) {
profileData.value = profile;
}
} finally {
isLoading(false);
}
update();
}
@override
void onClose() {
super.onClose();
}
}
个人资料视图
class ProfileView extends StatelessWidget {
final _profileController = Get.put(ProfileController());
@override

return Obx(() {

return Center(child: CircularProgressIndicator());
} else {
return Scaffold(
appBar: AppBar(

如何更新Get.back()上的数据？
附言打开FollowPersonalView页面时是否可以完全控制数据检索功能的启动？
