我有一个数据库并从 Firestore 中检索我的数据。
class ProductProvider with ChangeNotifier {
UserModel userModel;
List<UserModel> userModelList = [];
Future<void> getUserData() async {
List<UserModel> newList = [];
User currentUser = FirebaseAuth.instance.currentUser;
QuerySnapshot userSnapshot = await FirebaseFirestore.instance
.collection("Manufacturer-Accounts")
.get();
userSnapshot.docs.forEach(
(element) {
if (currentUser.uid == element.data()['Manufacturer_ID']) {
userModel = UserModel(
userFName: element.data()['FirstName'],
userCompany: element.data()['Company'],
userDesignation: element.data()['Designation'],
userEmail: element.data()['Email'],
userPhone: element.data()['PhoneNumber'],
userLastName: element.data()['LastName'],
);
newList.add(userModel);
}
userModelList = newList;
},
);
}
我已将我的数据作为列表检索并在有状态小部件中将其设置为 textformfield，因为我知道 TextEditing 控制器应该在有状态小部件中启动，而不应该是最终的。

但是仍然遵循程序，我面临一个问题，例如当我向控制器输入新值时，当我的键盘退出时它仍然显示一个新值。尝试了很多方法，仍然有同样的问题。
