flutter vs android native in battery consumption & apk size?

I can see some buzz around flutter. Lot of people write about it, but I can't get actual answer to these questions:

• How does battery consumption of native android (Java) app & a flutter app compare? Does it help that flutter compiles to native code? (correct me if I am wrong)

• How larger are flutter apps compared to native java apps? Is the size difference consistent or does it scale up with size / functionality of the app?

Battery consumption depends on the type of app you're creating. It's not like that the apps built with Flutter eat a lot of battery. And yes, Flutter compiles to native code.

How larger are flutter apps compared to native java apps? Is the size difference consistent or does it scale up with size / functionality of the app?

Size of a simple Hello World app in Android is around 4.06 MB and for iOS it is 10.8 MB. You can find more info here.
