Error running Flutter app on Android Emulator

Question

Im pretty new to Flutter & Im attempting to run an app on the Android Emulator (works fine on the browser but not the emulator). Im getting this error whenever I attempt to run the command 'flutter run':

Error running path. Default activity not found
Unable to read manifest info from
/Users/tazar/Downloads/ethereal-meditations-app-made-app-runnable/build/app/outputs/flutter-a
pk/app.apk.
No application found for TargetPlatform.android_arm64.
Is your project missing an android/app/src/main/AndroidManifest.xml?
Consider running "flutter create ." to create one.

What's really strange about this is that I DO have a declared Main activity in my AndroidManifest.xml file. I have it declared & everything so I don't understand why I'm getting this error in the place. Here is my manifest file in case that can be of use:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="path">
   <application
        android:label="app name"
        android:icon="@mipmap/ic_launcher">

              android:value="@string/facebook_app_id"/>

          <activity android:name="com.facebook.FacebookActivity"
              android:configChanges=
                      "keyboard|keyboardHidden|screenLayout|screenSize|orientation"
              android:label="@string/app_name" />

</manifest>

Any assistance would be greatly appreciated. Thank you in advance.
