페이지 616~624에 나와있는 그대로 따라했으나, 로그인 버튼을 눌렀을 때 계속해서 아래와 같은 경고 메시지가 발생하며,

로그인이 터미널에는 619페이지에 있는

"name": "[DEFAULT]",

이 내용도 뜨지 않습니다.

위와 같은 경고 메시지가 터미널에 나옵니다.

또한,
iOS Bundling complete 30ms
LOG [TypeError: Cannot read property 'fromModule' of undefined]이란 에러도 뜹니다.

파일 주소 입니다.

안녕하세요 @Kwon9tae

파일 일부만 선택해서 올리는 것이 아니라, 프로젝트 전체를 깃헙에 올려주세요. 그래야 정확한 확인이 가능합니다.

619페이지에 있는 콘솔 내용이 나타나지 않는것은 console.log를 이용해서 app을 확인하는 코드가 없어서 그렇습니다.
로그인 버튼 관련 코드상 보이는 특별한 문제는 없습니다.
이미지를 사용할 때, 경로는 정대경로(ex. C:...)를 사용하지 말고, 상대경로(ex. ../../img.png)를 사용하세요.

감사합니다.

파일 전체 올렸습니다. 감사합니다.

src/navigations/Navigation.js 파일 5번 라인 오타 있습니다.

import Asset을 import {Asset} 으로 변경하세요.

- import Asset from 'expo-asset';
+ import { Asset } from 'expo-asset';

로그인 버튼을 눌렀을 때 나타나는 문제는 Asset.fromModule에서 문제가 생기면서
그 아래라인에 있는 initFirebase()가 호출이 안돼서 발생한 문제입니다.

그리고 C:\... 으로 경로 작성하신 부분 ../../assets/... 형태로 변경하세요.

감사합니다.
