/**
 * Returns a {@link UserCredential} from the redirect-based sign-in flow.
 *
 * @remarks
 * If sign-in succeeded, returns the signed in user. If sign-in was unsuccessful, fails with an
 * error. If no redirect operation was called, returns `null`.
 *
 * This method does not work in a Node.js environment.
 *
 * @example
 * ```javascript
 * // Sign in using a redirect.
 * const provider = new FacebookAuthProvider();
 * // You can add additional scopes to the provider:
 * provider.addScope('user_birthday');
 * // Start a sign in process for an unauthenticated user.
 * await signInWithRedirect(auth, provider);
 * // This will trigger a full page redirect away from your app
 *
 * // After returning from the redirect when your app initializes you can obtain the result
 * const result = await getRedirectResult(auth);
 * if (result) {
 *   // This is the signed-in user
 *   const user = result.user;
 *   // This gives you a Facebook Access Token.
 *   const credential = provider.credentialFromResult(auth, result);
 *   const token = credential.accessToken;
 * }
 * // As this API can be used for sign-in, linking and reauthentication,
 * // check the operationType to determine what triggered this redirect
 * // operation.
 * const operationType = result.operationType;
 * ```
 *
 * @param auth - The {@link Auth} instance.
 * @param resolver - An instance of {@link PopupRedirectResolver}, optional
 * if already supplied to {@link initializeAuth} or provided by {@link getAuth}.
