안녕하세요. Firebase와 Google sign_in 사용중입... - 인프런

선생님, 안녕하세요.

지금까지의 Flutter 강의 잘 보았습니다. 정말 큰 도움이 됐습니다. 감사합니다.

현재, Firebase로 Firestore, 인증, Firebase사용중입니다.

이슈는

1. 에뮬레이터에서는 Firebase로의 Data를 얻어오지만,

- flutter build apk 를 해서 얻은 apk로 제 스마트폰에 설치하였을 때는, 로드가 되지 않습니다.

2. 에뮬레이터로 실행했을 때, Android studio가 여러가지 에러메세지를 보여줍니다.

스크린샷은 아래 링크에 있습니다.

Flutter Project는 위에 Github에 있습니다.

아래는 에러메세지 입니다.

════════ Exception caught by widgets library ═══════════════════════════════════════════════════════

The following assertion was thrown while applying parent data.:

Incorrect use of ParentDataWidget.

The ParentDataWidget Expanded(flex: 1) wants to apply ParentData of type FlexParentData to a RenderObject, which has been set up to accept ParentData of incompatible type ParentData.

Usually, this means that the Expanded widget has the wrong ancestor RenderObjectWidget. Typically, Expanded widgets are placed directly inside Flex widgets.

The offending Expanded is currently placed inside a RepaintBoundary widget.

The ownership chain for the RenderObject that received the incompatible parent data was:

ConstrainedBox ← Container ← StreamBuilder<QuerySnapshot> ← Expanded ← ImageSwiper ← RepaintBoundary ← IndexedSemantics ← NotificationListener<KeepAliveNotification> ← KeepAlive ← AutomaticKeepAlive ← ⋯

When the exception was thrown, this was the stack:

#0 RenderObjectElement._updateParentData.<anonymous closure> (package:flutter/src/widgets/framework.dart:5649:11)

#1 RenderObjectElement._updateParentData (package:flutter/src/widgets/framework.dart:5665:6)

#2 RenderObjectElement.attachRenderObject (package:flutter/src/widgets/framework.dart:5686:7)

#3 RenderObjectElement.mount (package:flutter/src/widgets/framework.dart:5380:5)

#4 SingleChildRenderObjectElement.mount (package:flutter/src/widgets/framework.dart:5833:11)

지금까지 해결을 위해

* Firebase 보안 설정 수정, 인증된 사람만 read/write 할 수 있도록

* settings.gradle 수정

- https://stackoverflow.com/questions/61732409/plugin-project-firebase-core-web-not-found

* pubspec.yaml 버전 최신으로 수정

이후 남은 시도는

* Firebase 프로젝트 이전.

* Flutter code refactoring

으로 생각하고 있습니다.
