Flutter VS Code attaching to app after app has been terminated to Debug deeplinks

Question

This is proving very difficult for me to debug. On Android, a FlutterFire deep link opens the App, but there are no URL data in the link. On iOS it is fine.

Debugging this isn't easy. I can run the App on the Emulator from VSCode, but to debug from terminated states I need to swipe the App up, but as soon as I do this I lose the debug connection.

Is it possible to reattach the debugger to the Android App after termination using VSCode?

And secondly,

Are there any command-line arguments that would pass the deep link on the initial run in the same way that it would get it from a terminated state?

I tried -d, but that doesn't work at all. I've hunted high and low for examples but come up with nothing.

Any pointers would be hugely appreciated.

Answer 1

Run the app in release mode so you can also run it when it is in closed state. use this command: flutter run --release

I know this question is very old, but since it is the first question you will find on this topic. I will link to the answer, which includes a workaround (not a good one, but better than nothing) https://stackoverflow.com/a/78205185/22264456
