spotify-web-api-ts-sdk AuthorizationCodeWithPKCEStrategy broken on React Native

[murray-lang]

I'm new to both Spotify development and React Native development, so please forgive me if I betray too much lack of understanding.

• I'm building a custom Spotify player using React Native, currently targeting Android.
• In my app, I'm using the @spotify/web-api-ts-sdk npm package, rather than building the web-api-ts-sdk sources into my bungles.
• When the app runs in the Android emulator, I get the exception "Cannot read property 'search' of undefined" in the function redirectOrVerifyToken(), particularly the line: const hashParams = new URLSearchParams(window.location.search); ...but I believe it's expected that location is undefined in the window object of a React Native application.

So it looks to me that this code was not written with React Native in mind, and will never work. Is this code wrong or am I wrong? Is it my error to expect AuthorizationCodeWithPKCEStrategy to be relevant to React Native?

It looks like I'll need to write an implementation of IAuthStrategy based on an expo AuthSession. I'm trying this based on: https://medium.com/@zachrach/spotify-web-api-authorization-with-react-native-expo-6ee1a290b2b0 ...though I'm not happy with the handling of the client secret. I'll worry about that later.
