Variables are not strictly typed

[jhalborg]

Issue Description

Give the query

export const GET_ROCKET_INVENTORY = gql(/* GraphQL */ `
  query FilmById($id: ID!) {
    film(id: $id) {
      title
    }
  }
`);

the following type is generated:

It correctly validates that id must be a variable of type String

and that it is requried

but it allows for random arguments to be passed

I would expect an error for variables that are unused in the query.

Reproduction Steps

Run the example, and see that you get no Typescript errors for the invalid variable in renderQuery.tsx

Hey there, thanks for the report!

We already have a merged PR for this: #10506

In version 3.8, this behavior will be as you expect - we didn't want to introduce it in 3.7 as it changes the behavior a bit too much for a "patch"!
