Steps to reproduce

  1. Create a new flutter project on flutter 3.29.0 and use the code provided in main.dart. On my phone, after reaching around 600 to 1400 icons, the app crashes due to an out of memory segfault and it lags heavily up until then. Remove line 64: shadows: [const Shadow(blurRadius: 4)],, and there is no crash (i let it run up to 6000 easily with no shadows). I tested on a Z flip 6 running android 14 (oneui 6.1.1)

Expected results

No crash

Actual results

Crash

Code sample

Code sample 
import 'dart:async';
import 'dart:math';

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(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _count = 200;

  @override
  void initState() {
    // TODO: implement initState
    Timer.periodic(Duration(seconds: 1), (_) {
      setState(() {
        _count += 50;
      });
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,

            for (int x = 0; x < sqrt(_count); x++)
              Row(
                children: [
                  for (int y = 0; y < sqrt(_count); y++)
                    Icon(
                      shadows: [const Shadow(blurRadius: 4)],
                      Icons.bolt,
                      size: 14,
                      color: Colors.grey[300],
                    ),
