How to view Flutter debug console output for a release version of the app?

Using print() to log messages works in debug mode and I can see output in debug console of VSCode or in terminal. How can I get those with release build ? I have seen release build producing such logs but not sure how to get those.

How do you show logs in release mode in flutter?

Open Android Studio with a dummy Android project (not Flutter). You'll find the Logcat pane on the bottom. That shows all the logs of all the apps running on your device. Filter by "flutter" and you should see logs of all Flutter apps running on that device.

Run

$ flutter logs

in terminal with terminal opened in a flutter project directory, connect phone with computer and use the release version of the app on phone to see logs similar to the debug version shows.

Edit: Not sure if this works for iOS.
