Thanks for reporting the issue.

I wasn’t able to reproduce it on my side. Could you share a minimal code example to help me reproduce it? It might be related to a specific combination of configurations. Also, it would be helpful to know the exact device you encountered the issue on and whether it was an emulator or a physical device.

Test Device: iPhone 12 OS: 18.5

This crash happens only for a view videos, not for all.

I attached the video and screenshot of app. You can produce it if you load the video and press the save/export button.

I also attached my entire code. Kindly rename this file to .dart

Code: VideoEditorScreen.txt
