Memory overhead of embedding Godot in Flutter/RN for minimal data exchange

Godot Version

Hi everyone, I’m planning to use Godot inside a Flutter (or React Native) app as a library. My use case is specific:

  1. Flutter will handle SDKs like IAP (Billing) and Ads.

  2. Godot will handle the actual gameplay.

  3. Data exchange between them will be minimal (only at the end of a session or for IAP).

  4. While the game is running, there will be NO communication with the host (Flutter/RN).

My question is: In this “Idle” state of the host framework during gameplay, how much baseline memory (RAM) overhead should I expect? Does the Flutter/RN engine stay in a low-power state, or will it significantly eat into the memory budget that Godot needs for the game?

Thanks for your insights!
