Support for React Native via expo/fetch in @electric-sql/react

[ZainNemat]

I’ve been working on integrating ElectricSQL into a React Native app built with Expo, and it got me thinking would it make sense to build a version of the @electric-sql/react hook layer tailored specifically for Expo, using expo/fetch internally instead of the default fetch()?

While exploring the implementation, I noticed a few places where the standard fetch() is used directly, which can lead to issues in Expo environments particularly on Android where native fetch can be slow or unreliable.

I know there’s the fetchClient prop available to customize the fetch logic, which is great but I was wondering if it might make sense to have a dedicated, Expo-friendly hook layer (even as a small wrapper package) that integrates expo/fetch by default in a clean and reliable way.

They have this API in order for consistent behavior across mobile platforms, it has some differences from the standard fetch when used in react native environment.

We should fix any cases where we don't use the fetchClient.

Perhaps we could export a useShapeExpo or something which uses expo/fetch by default.

Or just document the pattern.

Exporting a useShapeExpo sounds like a great idea!
I'm interested in contributing to making it happen if possible.
I can test it out on expo then to see if it resolves the slowness on android then.
