Wheel breaks when wrapped with FittedBox & SizedBox

[LenaWirtz]

Hi all,

i created a very simple flutter project (version 3.3.9, Picker version 3.0.2). when wrapping the Scaffold with a Fitted & Sized box as you see in the example code below, the touch points of the color wheel are broken (like in the video). Is there any way to fix this?

`
import 'package:flex_color_picker/flex_color_picker.dart';
import 'package:flutter/material.dart';

void main() {
runApp(const MyApp());
}

class MyApp extends StatelessWidget {
const MyApp({super.key});

@OverRide
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}

class MyHomePage extends StatefulWidget {
const MyHomePage({super.key, required this.title});
final String title;

@OverRide
State createState() => _MyHomePageState();
}

class _MyHomePageState extends State {
Color currentColor = Colors.blue;

@OverRide
Widget build(BuildContext context) {
return FittedBox(
child: SizedBox(
width: 1920,
height: 1080,
child: Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: ColorPicker(
pickersEnabled: const <ColorPickerType, bool>{
ColorPickerType.wheel: true,
ColorPickerType.primary: false,
ColorPickerType.accent: false,
},
wheelDiameter: 500,
wheelSquarePadding: 50,
wheelWidth: 40,
wheelSquareBorderRadius: 16,
enableShadesSelection: false,
color: currentColor,
onColorChanged: (value) {
setState(() {
currentColor = value;
});
},
),
),
),
),
);
}
}

It seems to be working. The painted wheel seems to have a diameter of 500 in the video as specified and it works.

What do you expect it to do?

Please note that the wheel is fixed size painter, kind of like e.g. Switch, it does not expand/shrink to fit surrounding constraints. You can of course compute the max diameter of the the wheel that would fit into the area you have and give that as diameter, if you need it to respond to available space.
