How to constrain ListTile in widget hierarchy - flutter

Question

How can I make a ListTile work inside this widget hierarchy:
SingleChildScrollView(
scrollDirection: Axis.vertical,
child: Column(
children: [
Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Radio(
value: 1,
groupValue: 1,
onChanged: (sel) {},
),
GestureDetector(
child: Row(
children: <Widget>[
//Text('Title'), -- This is OK, but ListTile fails
ListTile(
title: Text('Title'),
subtitle: Text('Subtitle'),
),
],
),
onTap: () {},
),
],
),
],
),
),
Please understand that I am not in full control of the widget hierarchy -- a framework is building the SingleChildScrollView, Radio, GestureDetector, etc. I am simply trying to supply a child widget for an option. (I replicated the hierarchy in a simplified form to debug and experiment.)
I'm getting an exception:
flutter: ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
flutter: The following assertion was thrown during performLayout():
flutter: BoxConstraints forces an infinite width.
flutter: These invalid constraints were provided to RenderParagraph's layout() function by the following
flutter: function, which probably computed the invalid constraints in question:
flutter: _RenderListTile._layoutBox (package:flutter/src/material/list_tile.dart:1318:9)
flutter: The offending constraints were:
flutter: BoxConstraints(w=Infinity, 0.0<=h<=Infinity)
Normally when I encounter this kind of problem, I simply wrap the widget in an Expanded, but that is not working in this case.
Note that if I replace the ListTile with a simple Text widget, then it renders fine.

Answer 1

You can wrap the ListTile in a Container or a ConstrainedBox and set its maxWidth:
ConstrainedBox(
constraints: BoxConstraints(
maxWidth: MediaQuery.of(context).size.width - 50,
),
child: ListTile(
title: Text('Title'),
subtitle: Text('Subtitle'),
trailing: Text('Trailing'),
),
),

Answer 2

You can copy paste run full code below
You can use IntrinsicWidth wrap Row and Expanded wrap ListTile and you can have more than one Expaned ListTile
GestureDetector(
child: IntrinsicWidth(
child: Row(
children: <Widget>[
//Text('Title'), -- This is OK, but ListTile fails
Expanded(
child: ListTile(
title: Text('Title'),
subtitle: Text('Subtitle'),
),
),
],
),
),
