Unlimited vertical space - flutter

Question

Hi I'm working on a project that requires a ListView builder sadly when ever I try to put in that ListView builder this the error I get:
════════ Exception caught by rendering library ═════════════════════════════════
Vertical viewport was given unbounded height.
The relevant error-causing widget was
ListView
lib\screens\questionScreen.dart:50
════════════════════════════════════════════════════════════════════════════════
════════ Exception caught by rendering library ═════════════════════════════════
RenderBox was not laid out: RenderViewport#18955 NEEDS-LAYOUT NEEDS-PAINT NEEDS-COMPOSITING-BITS-UPDATE
'package:flutter/src/rendering/box.dart':
Failed assertion: line 1940 pos 12: 'hasSize'
here is my code:
Scaffold(
body: Container(
alignment: Alignment.center,
width: MediaQuery.of(context).size.width - 20,
padding: EdgeInsets.fromLTRB(20, 120, 20, 50),
child: Column(
children: [
Text(
questions[question.getListNumber()].soru,
style: TextStyle(fontSize: 40),
),
ListView.builder(
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return ListTile(
tileColor: Colors.white,
);
},
),
],
),
));

Answer 1

just set shrinkWrap: true property and wrap the ListView.builder with an Expanded, it will solve everything, or if you have any fixed size for the ListView.builder wrap in a SizedBox/Container with the fixed size.

Answer 2

You are giving infinite space to an unbounded widget. Your ListView is inside of the Column should be wrapped with a finite space widget such as container.
Scaffold(
body: Container(
alignment: Alignment.center,
width: MediaQuery.of(context).size.width - 20,
padding: EdgeInsets.fromLTRB(20, 120, 20, 50),
child: Column(
children: [
Text(
questions[question.getListNumber()].soru,
style: TextStyle(fontSize: 40),
),
Container(
child: ListView.builder(
itemCount: 1,
itemBuilder: (BuildContext context, int index) {
return ListTile(
tileColor: Colors.white,
);
},
),
),
],
),
));
