[desktop_multi_window] App is crashing while closing windows #352
Description
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
steps-to-reproduce-the-issue.mp4
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.
