ShowAlertDialog Flutter Render Bug - flutter

Question

I'm having a problem which i have been trying to solve for the last 3 hours but it's pointless.
Now get to the point, I'm making an custom CupertinoDialog, everything looks good to me. Idk why is this happening. I've try multiple method on Stackoverflow but it's pointless. I hope someone can save me from this bug.
======== Exception caught by rendering library =====================================================
The following assertion was thrown during performLayout():
RenderBox was not laid out: RenderIntrinsicWidth#b0789 relayoutBoundary=up5 NEEDS-PAINT
'package:flutter/src/rendering/box.dart':
Failed assertion: line 1930 pos 12: 'hasSize'
Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:

The relevant error-causing widget was:

Here's my code:
void showAlertDialog(BuildContext context, String title, String content) {
showCupertinoDialog(
context: context,
builder: (builder) => SimpleDialog(
title: title.text.semiBold.make().centered(),
children: [
content.text.make().centered().expand(),
Row(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Container(
width: 100,
child: OutlinedButton(
style: OutlinedButton.styleFrom(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(4)),
side: BorderSide(color: Colors.red, width: 1.0), // HERE
),
side:
BorderSide(color: Colors.red, width: 1.0)), // AND HERE
onPressed: () {},
child: 'Cancel'.text.color(Colors.red).make(),
),
),
Container(
width: 100,
child: TextButton(
onPressed: () {},
child: 'OK'.text.white.make().px(15),
style: ButtonStyle(
backgroundColor: MaterialStateProperty.all(Colors.red),
),
),
),
],
),
],
),
);
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: Padding(
padding: const EdgeInsets.all(50.0),
child: GestureDetector(
onTap: (){
showAlertDialog(context, "tit", "Content");
},
child: ClipPath(
clipper: MyClip(),
child: Container(
width: 200,
height: 300,
color: Colors.lightGreenAccent,
),
),
),
),
);
}
}

Answer 1

#Nobody,
As pskink mentioned, try to use Text(content), I just replaced
title: title.text.semiBold.make().centered()
for
title: Text(title)
and
content.text.make().centered().expand()
for
Row(mainAxisAlignment: MainAxisAlignment.center,
children: [Text(content)],)
and it works, I've never used velocity_x, but it seems that's the problem
