Whenever I click a text field, the keyboard opens for a split second and closes. There are no errors in the debug menu as well. I have a login page that is in development, and it has nothing but a TextFiled() empty widget. It's working fine.
How it worked: I removed key: scaffoldkey (but then drawer will not open)
Here is my HomePage file
import 'package:flutter/material.dart';
import 'package:resturant/constant.dart';
import 'package:resturant/widgets/items.dart';
import 'package:resturant/widgets/sidemenu.dart';
import 'package:resturant/widgets/welcome.dart';
class HomePage extends StatefulWidget {
const HomePage({super.key});
@override
State<HomePage> createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> with TickerProviderStateMixin {
@override
Widget build(BuildContext context) {
TabController tabController = TabController(length: 3, vsync: this);
var scaffoldkey = GlobalKey<ScaffoldState>();
double devicewidth = MediaQuery.of(context).size.width;
double deviceheight = MediaQuery.of(context).size.height;
return PopScope(
canPop: false,
child: SafeArea(
child: Scaffold(
resizeToAvoidBottomInset: false,
backgroundColor: const Color(0xFFFFF5F5),
key: scaffoldkey,
drawer: const SideMenu(),

onPressed: () {
scaffoldkey.currentState!.openDrawer();
},

Tab(

],
))
],
),
),
// List of food items
Expanded(
flex: deviceheight > 830 ? 8 : 8,
child: TabBarView(controller: tabController, children: [
const ItemsWidget(),
Container(

color: Colors.yellow,
),
Container(
width: devicewidth,

])),

}
}
I don't know how I can make both work together the drawer open drawer and textfield. Can someone help me with this?

Reset to default 0scaffoldkey should not be initialized inside build, when keyboard is showing, build will be invoked, then created a new scaffoldkey, a new Scaffold, then keyboard will hide immediately, just move scaffoldkey outside like below
class _HomePageState extends State<HomePage> with TickerProviderStateMixin {
var scaffoldkey = GlobalKey<ScaffoldState>();
}
By making the scaffoldKey static, you ensure it is not recreated during widget rebuilds caused by the keyboard opening or closing. This stabilization prevents the issue of the keyboard unexpectedly closing
import 'package:flutter/material.dart';
import 'package:resturant/constant.dart';
import 'package:resturant/widgets/items.dart';
import 'package:resturant/widgets/sidemenu.dart';
import 'package:resturant/widgets/welcome.dart';
class HomePage extends StatefulWidget {
const HomePage({super.key});
@override
State<HomePage> createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> with TickerProviderStateMixin {
// make the scaffoldKey static
static var scaffoldkey = GlobalKey<ScaffoldState>();
}
The issue occurs because the GlobalKey used for the Scaffold and the TextField is not being utilized properly to manage focus. When the TextField is tapped, the FocusNode loses focus, likely due to the widget rebuilding or interference from the GlobalKey handling.
TabController is not handled properly each time user focus on TextField TabController will re-initialised.
Updated Code:
class HomePage extends StatefulWidget {
const HomePage({super.key});
@override
State<HomePage> createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> with TickerProviderStateMixin {
late TabController tabController;
@override
void initState() {
tabController = TabController(length: 3, vsync: this);
super.initState();
}
var scaffoldkey = GlobalKey<ScaffoldState>();
double defaultPadding = 10;
@override
Widget build(BuildContext context) {
double devicewidth = MediaQuery.of(context).size.width;
double deviceheight = MediaQuery.of(context).size.height;
return PopScope(
canPop: false,
child: SafeArea(
child: Scaffold(
resizeToAvoidBottomInset: false,

resizeToAvoidBottomInset: true, This allows the screen to resize when the keyboard appears, preventing the immediate collapse of the keyboard after opening theTextField. – Visal Commented Nov 20, 2024 at 7:27
