Flutter, how to have release and debug app on the same device?

I'm working with flutter on an application (only android for now) which can be downloaded from Google Play. I have installed the released app on my phone. However, whenever I launch the debug on my device with android studio, it is deleting the released version. What I would want is having both apps at the same time, like "App" and "App_debug" on my device.

How can I set up my project so there is no conflict between the debug and the release app ?

Thank you.

What're you looking for is called flavors. You can check out more info about it in the flutter official docs or checking out these packages:

I managed to found a solution (only for android).

To not delete the "released App" download from Google Play, I add these lines in the file android/app/build.gradle:

android {
    buildTypes {
        // ------ Start Changes -----
        debug {
            applicationIdSuffix ".debug"
        }
        // ----- End Changes -----
    }
}

In that way the package will be com.example.app for a release app and com.example.app.debug for my debug app and there is no conflict anymore.

However I also wanted a different app name so I can differenciate both apps. To do so I followed this comment:

In the file android/app/src/main/AndroidManifest.xml I made this change:

<manifest ...>
    <application
        // before : android:label="App"
        android:label="@string/app_name"    // <- After my changes
    >
    </application>
</manifest>

Then to set up the name for the release app, create or modify the file android/app/src/main/res/values/string.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">App</string>
</resources>

And for the debug version, create or modify the file android/app/src/debug/res/values/string.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">App Debug</string>
</resources>
