capacitor-firebase: bug: authStateChange never fires.

Plugin(s): “@capacitor-firebase/authentication”: “^0.5.0”

Platform(s): Android

Current behavior: When using const result = await FirebaseAuthentication.signInWithGoogle() for example, the login is successful and result.user is returned. However, authStateChange is never fired. Note that this works in web, but NOT on Android.

Expected behavior: authStateChange needs to be fired on any change in auth state, e.g. re-opening app or signing out.

Steps to reproduce:

Related code:

  // capacitor.config.json
  "plugins": {
    "FirebaseAuthentication": {
      "skipNativeAuth": false,
      "providers": ["twitter.com", "google.com", "facebook.com"]
    },
  }

// main.ts
import { FirebaseAuthentication } from "@capacitor-firebase/authentication";
FirebaseAuthentication.removeAllListeners().then(() => {
  FirebaseAuthentication.addListener("authStateChange", (result) => {
    if (result.user) {
      // this never fires
    } else {
      // this never fires
    }
  });
});

  // Login.vue
  const signInWithGoogle = async () => {
    try {
      const result: SignInResult = await FirebaseAuthentication.signInWithGoogle();

      if (result.user) {
        return result.user;
      }
    } catch (err) {
      console.log(err);
    }
  };
