Steps to reproduce

1. Clone https://github.com/rohit11/Flutter_PlatformView.
   I stumbled upon this public example when trying to reproduce this issue without setting up too much myself, and it perfectly illustrates the problem. Thanks rohit11 ;)

2. Replace myapp.dart with the one from CodeSample

3. Tap the button

Expected results

Tapping the Button does not affect the devices memory, as the button itself has no logic in its onPressed.

Actual results

Tapping the Button increases the apps memory usage indefinitely until it is killed by the os.

Code sample

import 'package:flutter/material.dart';

class MyApp extends StatelessWidget {

  Widget build(context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Platform View'),
        ),
        body: SafeArea(child: Stack(children: [
          SizedBox(
            width: 380,
            height: 380,
            child: UiKitView(
              viewType: 'NativeView',
            ),
          ),
          Stack(
            children: List<Widget>.generate(10000, (index) {
              // The problem already happens with a small amount of widgets.
              // Using an excessive amount of widgets is just to make the problem more evident.
              return Text("Lots of Texts represent a Widget with complex components.");
            }),
          ),

          Align(
            alignment: Alignment.bottomCenter,
            child:
            TextButton(
              child: Text("Button"),
              onPressed: () {
                print("Tap ${DateTime.now()}");
              },
            ),
          ),
        ],
        ),
        ),
      ),
    );
  }
}

Screenshots or Video

As far as I can tell, there are IOGPUMetalResources allocated, which are never released and persist until the App runs out of memory?

Note

Please note, that I am using a flutter 3.24.1 user-branch in the flutter doctor output as I have played around with this bug for a while. It does happen on the stable 3.24.1 version as well.
I am also currently using the MacOS Sequoia Beta including the xCode 16 Beta, but had the same issue a few weeks before when I was still using the official MacOS release with xCode 15.4.

The memory also only appears in the xCode memory profiler, not in the flutter profiler.
