TypeScript types taken as literals

Type definitions are a little weird. I’m having TS get angry with Animated Values. When I pass a number as a Value, it takes it as a literal. Current workaround is to pass a number with <number> to force the type. Otherwise, it will take my 0 or whatever else I pass it as the type, literally.

Very weird. I have always passed the type parameter so never seen this issue.

Changing the definitions to something like this seems to work:

class AnimatedValue<T extends Value> extends AnimatedNode<T> {
  constructor(value?: T);

  setValue(
    value: Adaptable<
      T extends number
        ? number
        : T extends string
        ? string
        : T extends boolean
        ? boolean
        : T
    >
  ): void;
}

NOTE: probably should be done in the Adaptable class instead of here.

Looks super ugly though.

Hey, I’m sorry for the late response 😔

I think this issue may be outdated now, so I’m closing it.
