App Freeze When Not Providing The 'itemCount' of AlignedGridView.count

[00Adnan00]

When using AlignedGridView.count without specifying the itemCount parameter, the Flutter app freezes completely.

This is minimal code to reproduce the issue:

import 'package:flutter/material.dart';
import 'package:flutter_staggered_grid_view/flutter_staggered_grid_view.dart';

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: AlignedGridView.count(
          crossAxisCount: 2,
          itemBuilder: (_, index) => Text('Item $index'),
        ),
      ),
    );
  }
}
