[BUG] App Crash-Bug

Describe the bug I’ve been referred to this github page by the Flutter-Multi-Image-Picker Devs as they use your package. When opening an image picker in a flutter app, the app crashes with the following stack-trace:

Smartphone (please complete the following information):

• Device: FairPhone 2
• OS: Android 7.1.2
• Native App
• Flutter 4.5.8

Additional Info: The multi-image-picker is AndroidX based and the flutter app needs to be AndroidX based as well.

Nevermind this just delayed the problem. Now instead of crashing when opening the picker it crashes when selecting a picture.

However recreating a fresh flutter install, copying lib and going through the install steps of all plugins solved the problem for me. My app was created long ago and some step in the various upgrades / migrations must have been wrong

[SylvainLosey]

Yes apparently in my app the startInAllView option of the multi_image_picker flutter plugin is causing a crash when opening the image picker. However it doesn’t seem to happen on their example app.

FYI: To reproduce the issue, the emulator must have a high DPI otherwise another bug with the exact same manifestation happens (app crashes when opening the image picker): https://stackoverflow.com/questions/49261555/system-ui-has-stopped-emulator-when-requesting-permissions. It also only seems to happen in release mode.
