Crash In SwiftAppTrackingTransparencyPlugin.register When Manual Launching Debug Build

[samdeane]

Launching via VSCode/XCode onto a hardware device works fine.
However, if I the launch the same binary manually on the device, it crashes on startup.

Looking at the crashlog, it seems to be dying in SwiftAppTrackingTransparencyPlugin.register(with:).

Having the same issue. Anyone found a solution for this?

I have the same problem, do you have a solution or the reason why this happens?

Finally found the issue and the solution!
It's not a problem of this plugin but of Apple. Apparently from version iOS 14 Apple does not allow to launch debug apps from the home screen. That is why they work from editors, but not manually from the device.

The solution is to create a release build.
If you don't want to create a release and upload it to TestFlight, here one explains how to do it from XCode: https://stackoverflow.com/questions/64669114/ios-14-not-letting-flutter-apps-still-in-dev-to-launch-from-the-home-screen-co
