Text position problems with UserAccountsDrawerHeader in the Drawer in flutter - flutter

Question

I am using a userAccountsDrawerHeader in the Drawer with a photo, username and email but I get a location or text positioning problem.
The text it shows is from the database using a future builder and it gives me a problem.
But when I test the properties of userAccountsDrawerHeader(accountName,accountEmail) using a Text widget with no data from the database, the text is located correctly, no problem there.
How can I solve that?
Your help would be greatly appreciated.
code and image::
UserAccountsDrawerHeader(
accountName:NombreCabeceraDrawer(),
accountEmail:CorreoCabeceraDrawer(),
),
class CorreoCabeceraDrawerextends StatefulWidget{return correocabeceradrawer ();}
class correocabeceradrawer extends State<CorreoCabeceraDrawer>{
Widget CorreoCabeceraDrawer(){
return Container(
child: Text(correousuario), ); }
#override
Widget build(BuildContext context) {
return Container(
child: FutureBuilder(
future: futureServices,
builder:(context, AsyncSnapshot snapshot) {
List listainfocabeceradrawer = snapshot.data;
if(snapshot.hasData ) {
return Center(
child: Container(
child: ListView.builder(
itemCount: listainfocabeceradrawer.length,
itemBuilder: (context,i){
correousuario = listainfocabeceradrawer[i].CorreoUsuario;
return Container(
child: CorreoCabeceraDrawer(),
); }), ),);
}else if(snapshot.hasError){
return Text("${snapshot.error}");
} return Center(
child: CircularProgressIndicator()
);
}
),
);
throw UnimplementedError();
}}

if we think simple is this code work with your code?
UserAccountsDrawerHeader(
accountName:NombreCabeceraDrawer(),
accountEmail:CorreoCabeceraDrawer(),
),
class CorreoCabeceraDrawerextends StatefulWidget{return correocabeceradrawer ();}
class correocabeceradrawer extends State<CorreoCabeceraDrawer>{
Widget CorreoCabeceraDrawer(){
return Container(margin:EdgeInsets.only(top:40),
child: Text(correousuario), ); }
#override
Widget build(BuildContext context) {
return Container(
child: FutureBuilder(
future: futureServices,
builder:(context, AsyncSnapshot snapshot) {
List listainfocabeceradrawer = snapshot.data;
if(snapshot.hasData ) {
return Center(
child: Container(
child: ListView.builder(
itemCount: listainfocabeceradrawer.length,
itemBuilder: (context,i){
correousuario = listainfocabeceradrawer[i].CorreoUsuario;
return Container(
child: CorreoCabeceraDrawer(),
); }), ),);
}else if(snapshot.hasError){
return Text("${snapshot.error}");
} return Center(
child: CircularProgressIndicator()
);
}
),
);
throw UnimplementedError();
}}
