if i remove SingleChildScrollView from layout then I'm getting below output when opening keyboard
I need to make my screen scroll-able
I have already checked below Stack-overflow links
- Flutter: RenderBox was not laid out
- How to solve ' RenderBox was not laid out:' in flutter in a card widget
- Flutter Another exception was thrown: RenderBox was not laid out: RenderRepaintBoundary#eaea6 NEEDS-LAYOUT NEEDS-PAINT
If need more information please do let me know. Thanks in advance. Your efforts will be appreciated.
Whole Exception log
════════ Exception caught by rendering library ═════════════════════════════════════════════════════
The following assertion was thrown during performLayout():
BoxConstraints forces an infinite height.
These invalid constraints were provided to RenderFlex's layout() function by the following function, which probably computed the invalid constraints in question:
RenderStack.performLayout (package:flutter/src/rendering/stack.dart:510:15)
The offending constraints were: BoxConstraints(w=392.7, h=Infinity)
User-created ancestor of the error-causing widget was:
SingleChildScrollView file:///home/ctpl119/Documents/NEW_PROJECT/oricon/oricon/lib/register.dart:23:15
When the exception was thrown, this was the stack:
#0 BoxConstraints.debugAssertIsValid.<anonymous closure>.throwError (package:flutter/src/rendering/box.dart:501:9)
#1 BoxConstraints.debugAssertIsValid.<anonymous closure> (package:flutter/src/rendering/box.dart:548:21)
#2 BoxConstraints.debugAssertIsValid (package:flutter/src/rendering/box.dart:552:6)
#3 RenderObject.layout (package:flutter/src/rendering/object.dart:1618:24)
#4 RenderStack.performLayout (package:flutter/src/rendering/stack.dart:510:15)

One important point. Performing hot reload - r won't show it correctly if your changes solved the issue or not. It always happens with this render box not laid situation. In order to see if your changes solved the issue you should Perform hot restart - R.

It's very easy, you just have to remove SingleChildScrollView. After That add one property to the Scaffold, that is
resizeToAvoidBottomInset: true
It might be working for you.
Example:
return Scaffold(
resizeToAvoidBottomInset: true,
body: SafeArea(child: Container())
);

I was facing a similar issue
Found out that the Spacer() widget was creating the UI render issue
This is not a solution to this question, but it might help someone
Thank you!

You can use ListView instead of SingleChildScrollView so no need for the column at first of the code.
@override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: ListView(
shrinkWrap: true,
children: <Widget>[
Form(...),
],
),),
);

I don't understand why you use stack .Without stack it works fine.
@override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: SingleChildScrollView(
child:Column(

Form(
key: _formKey,
child: new Theme(
