My issue arises from using an outdated type declaration package (@types/expo). To resolve this, I decided to update certain aspects of it by creating a new typing file like so: ./typings/expo/index.d.ts
import * as expo from 'expo';
declare module 'expo' {
var Icon: any;
var SplashScreen: any;
export interface AppLoadingProps {
startAsync?: () => Promise<void[]>;
}
}
While some parts have begun functioning correctly, I've encountered the following error:
[ts] Subsequent property declarations must have the same type.
Property 'startAsync' must be of type '(() => Promise<void>) | undefined',
but here has type '(() => Promise<void[]>) | undefined'
Despite searching on Google and TypeScript forums, I haven't found a satisfactory solution for this issue. Should I attempt to modify the interface with identical properties, or wait for the package to be updated on definitelyTyped?
Here is a glimpse of my tsconfig.json file:
