如何更新用户信息

Question

我想构建一个附加信息，该信息将显示在用户的个人资料中。因此，如果用户信息尚未更新，将要求他们更新其个人资料，该信息只会显示给个人资料所有者。那么它将向查看该个人资料的其他用户显示“此用户尚未更新要显示的个人资料信息”。如果配置文件已更新，则信息将显示在其配置文件中，并显示给查看该配置文件的任何用户。我该如何开发呢？

这是我到目前为止在个人资料上尝试过的内容

buildUserInfo() {
     bool isProfileOwner = currentUserId == widget.profileId;
     if(isProfileOwner) {
                      return Column(
                 mainAxisAlignment: MainAxisAlignment.start,
                 children: <Widget>[
                   Container(
                     alignment: Alignment.topLeft,
                     child: ListTile(
                       trailing: IconButton(
                         icon: Icon(Icons.edit),
                         onPressed: () => Navigator.push(context, 
                         MaterialPageRoute(builder: (context) => Information())
                       )),
                       title: Text(
                         'Update profile info'
                       ),
                     ),
                   ),
                   Divider(),
