[desktop_multi_window] App is crashing while closing windows
I encounter crashes in my app and in the plugin example app - the problem is random, sometimes easy to replicate but sometimes it can take a long time to reproduce it.
The app simply crashes from time to time when closing their windows.
Reproduce Steps
- build the example app(desktop_multi_window/example/lib/main.dart) from https://pub.dev/packages/desktop_multi_window plugin.
- create a set of windows e.g. 15 windows - by clicking on the "Create a new World!" button
- start closing them immediately by fast-clicking on the "x" window button
- repeat the above steps until the app crashes
https://github.com/user-attachments/assets/4f3f61c6-99e0-4b0b-8ac8-d13e955d8e48
Sometimes creating 3-4 sets of windows is enough to see the problem.. but sometimes you can create and close hundreds of windows without the issue.
This problem may seem rare because it's not easy to reproduce, but I have several instances of this happening throughout an 8-hour workday, so it's problematic.
Expected behavior
There is no crash inside the flutter code. The application is stable while creating and closing windows.
Actual results
The app is crashing randomly and is unstable. There is no way to handle that issue in the app code. The issue makes the multi-window app unusable.
Version (please complete the following information):
- Flutter Version: [3.22.3]
- OS: [Windows]
- plugin: [desktop_multi_window 0.2.0]

Exception:
Additionally, it seems it isn't the only place where the app crashes when using the plugin. Some extra logs from my app:
I reported it directly in the Flutter repository but was sent here: https://github.com/flutter/flutter/issues/152299
Hi @fufesou 👋
I saw that you made a great contribution 💪 to resolve the issue I reported some time ago: https://github.com/MixinNetwork/flutter-plugins/issues/283
It seems this issue is similar.. but we are crashing in different places inside the Flutter engine.. some details here: https://github.com/flutter/flutter/issues/152299
I committed a piece of code here that automates the crash reproduction: https://github.com/lukasz-lukasz-lukasz/flutter-plugins/commit/4ae8e28318187ee8936ffcccdd37c3d433e53f15
- all we need is to click one button and wait until the app crashes.. :)
Since you have experience with the previous issue, maybe you would like to help with this one if you have time.. 🙏 🙏 😄
I recently encountered this too, creating and opening randomness would crash the entire program,I hope the author can pay attention to it, thank you
@lukasz-lukasz-lukasz I think this should be a problem with flutter. It was normal before flutter was upgraded. When I upgraded to flutter 3.24, it crashed.
@lukasz-lukasz-lukasz @lingg4556 @NicholasHwang I fixed this issue, and it works well. I hope this can help you.

More related solutions:
Per this thread https://github.com/flutter/flutter/issues/155685, this MR is root cause of crashing
I just downgraded to Flutter v3.16.8 / Dart 3.2.5 and downgraded the associated packages
- This resolved all crashing
- Merged into Flutter on 1/23/2024, so just picked the Flutter release before it (v3.16.8)
If you don't want to use an old Flutter version, according to others, you can attempt to patch your current Flutter version by:
- reverting changes in this MR
OR
- using experimental patch https://github.com/flutter/flutter/issues/155685#issuecomment-2430293157
Have not tested any of these and personally wouldn't recommend it unless you have a good reason, as I imagine further debugging may be a headache
Will have to do it eventually, but that's a future me problem. Hopefully there's a better solution in the future
@weedsboy hallo, My problem is flutter 3.19.6, so I can modify like as your fix in 3.22.3?
@weedsboy hallo, My problem is flutter 3.19.6, so I can modify like as your fix in 3.22.3?
There have been big changes in Flutter from version 3.19 to 3.22. This might not work, but you can give it a try.

I have same crash on flutter 3.19.6, did you resolved on flutter 3.16.8?
Hey @NicholasHwang, yes, downgrading to flutter v3.16.8 fixed all crashing for me
@weedsboy hallo, I use 3.24.5 and modify as your MR. after build engine, I run desktop_multi_window example, it leak memory. do we have any solution to fix memory leak?

I haven't encountered any memory leaks yet. Can you see where the leak is?

For some reason, this doesn't work for me on 3.24.4. Is it just me?
Edit: Oh, it looks like I need to compile the engine. If you'd also send the dll, I'd appreciate it very much. My email is [mailto:[email protected]]
it's also not working on Flutter 3.35.2 • channel stable. Any workaround or solutions for now?
