You’re not developing for any vendor platforms, and are not developing for iOS or iPadOS here.
You’re developing an app for that multi-platform framework. Which is intended to be your tooling and APIs and interface (and not the Apple-provided native tooling that gets discussed around here), and to then use that framework to run on various platforms. You’re a layer or three away from the native tooling. Which means it’s best ask the folks that have provided the multi-platform framework for assistance.
Folks around here are familiar with how to do this with Apple development tools and platforms, but this forum isn’t the best spot for asking about problems and issues with Android Studio being used for multi-platform and cross-platform development.
If this is Flutter for instance, here are some suggested places to ask for help: https://flutter.dev/community
