Answer 1

When you are creating new Flutter project (from Android Studio menu), in file:

/android/app/build.gradle

which is there:

you have:

buildTypes {
    release {
        signingConfig signingConfigs.debug    //   <--- HERE YOU ARE USING DEBUG KEY
    }
}

Which means that release build (e.g. triggered from menu Build -> Flutter -> Build APK) will use debug key for signing.

Full build.gradle file (created by Android Studio):

Solution

Change from:

signingConfig signingConfigs.debug

to:

signingConfig signingConfigs.release

so (in build.gradle) you should have:

buildTypes {
    release {
        signingConfig signingConfigs.release
    }
}
