I would like to use the SingleChildScrollView in a pageView with vertical scrolling, the problem is that scrolls conflict and the pageview stops scrolling and only SingleChildScrollView starts scrolling. I needed to move the registration form above the keyboard.
the blue square is to show what I would like to move with the SingleChildScrollView
this is the main page:
return Scaffold(
resizeToAvoidBottomInset: false,
body: PageView(
controller: loginScreenPageController,
scrollDirection: Axis.vertical,
children: [
const RegisterPage(),
Column(children: <Widget>[
ClipRRect(
child: Container(
decoration: const BoxDecoration(
color: Colors.black,
),
height: MediaQuery.of(context).size.height / 100 * screenHeight,
width: MediaQuery.of(context).size.width,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text("NON HO UN ACCOUNT",
style: GoogleFonts.poppins(
color: Colors.white,
fontSize: 25,
)),
const Icon(
Icons.arrow_downward,
size: 100,
color: Colors.white,
),
SizedBox(
height: downArrowAnimationSize,
),
],
),
),
),
Expanded(
child: Container(
decoration: const BoxDecoration(
color: Color.fromARGB(255, 255, 133, 12),
),
height: MediaQuery.of(context).size.height / 2,
width: MediaQuery.of(context).size.width,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text("HO GIA' UN ACCOUNT",
style: GoogleFonts.poppins(
color: Colors.white,
fontSize: 25,
)),
const Icon(
Icons.arrow_upward,
size: 100,
color: Colors.white,
),
SizedBox(
height: downArrowAnimationSize,
),
],
),
),
),
]),
const LoginPage()
],
),
);
and this is the form page
Widget build(BuildContext context) {
return WillPopScope(
onWillPop: () async => false,
child: SingleChildScrollView(
child: Container(

_showMyDialog();
},
child: Text(

style: GoogleFonts.poppins(color: Colors.black),
)),
),
SizedBox(
height: MediaQuery.of(context).size.height / 100 * 5,
),
Row(

children: [

onPressed: () => _showMyDialog(),
child: Text("Facebook",

)
],
),

),
);
}
to understand if the phone keyboard is open I used this variable that is updated in the build
Widget build(BuildContext context) {
bool isKeyboardShowing = MediaQuery.of(context).viewInsets.vertical > 0;
return SafeArea(
child: Scaffold(
body: PageView(
scrollDirection: Axis.vertical,
children: [
Text(isKeyboardShowing ? "si" : "no"),
WillPopScope(
onWillPop: () async => false,

isKeyboardShowing ? null : NeverScrollableScrollPhysics(),

The safe area is important for not calculate the space for the sistem ui like notch
