¿De dónde se obtienen todas estas configuraciones en Firebase Console?

Actualización de septiembre de 2021:
Intentaré dividirlo lo más posible, pero hay muchas cosas por hacer.
Según la documentación, cuando trabajas con Flutter Web y Firebase, necesitas agregar tus dependencias de Firebase en tu index.html, así:Utilice las dependencias que desee, pero si no utiliza análisis, omítalas. Primero debes importar esto a través de firebasejs/8.6.1/firebase-app.js
Cannot read property 'app' of undefined at ServerResponse.render...
Si va a intentar autenticarse usando Google, también deberá agregar su token de Google Oath en este archivo.
Intente crearlo ahora, compruébelo e informe la petición.sí.
Esto también incluye agregar las dependencias en su archivo pubspec.yaml.

De nada, si no te importa votarlo y aceptarlo como respuesta, te lo agradecería.

Si alguien tiene problemas aquí, debe asegurarse de utilizar la versión 8.6.1, no la última versión 9.0.2.

Un error ortográfico en los parámetros de la función de devolución de llamada puede causar un error similar al anterior (por ejemplo, función (solicitud, respuesta))
