Description

opened on Dec 20, 2024

Steps to reproduce

  1. Run the code sample
  2. Note that there is an error in the console

Expected results

CarouselView should not throw when parent size is 0.

Actual results

CarouselView throws an AssertionError when parent size is 0.

The documentation for the itemExtent property mentions that the item extent should not exceed the available space that the carousel view occupies to ensure at least one item is fully visible. However, the same error is thrown when both the SizedBox and itemExtent is set to 0. I would also argue that the widget should gracefully handle having 0 size since this can happen indirectly through the parent widget size.

Additionally, an UnsupportedError (Unsupported operation: Infinity or NaN toInt) is thrown when the SizedBox size is set to 100 and itemExtent is set to 0.

Code sample

Code sample 
import 'package:flutter/material.dart';

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: SizedBox(
          width: 0,
          child: CarouselView(
            itemExtent: 100,
            children: [
              Container(
                color: Colors.red,
                width: 100,
                height: 100,
              ),
            ],
          ),
        ),
      ),
    );
  }
}

    I'll have a fix up soon, although most people on the framework team might be off on holiday, so the review could take a while.

    Edit: The tree is red on an issue with engine binaries (has been reported already), so I'll have to wait until that is resolved.

    Can someone remove the "waiting for PR to land" label? This is not fully fixed yet.
