flutter run

 

해결책 힌트 : https://brain-nim.tistory.com/146

 

나와 비슷한 문제가 있었던거 같다.

나는 flutter_inappwebview 패키지가 문제인듯 했다.

 

나도 똑같이 위 방법처럼 따라가 2곳 수정후 정상 작동함

 

1) AndroidManifest.xml에서 패키지명 확인

위치: C:\Users\{사용자명}\AppData\Local\Pub\Cache\hosted\pub.dev\{패키지명}\android\src.main.AndroidManifest.xml

AndroidManifest.xml에서 기존 namespace 확인

 

다음과 같이 수정함 : 패키지명 주석 처리함

AndroidManifest.xml에서 패키지명 주석처리

 

 

2) build.gradle에 namespace 추가

위치: C:\Users\{사용자명}\AppData\Local\Pub\Cache\hosted\pub.dev\{패키지명}\android\build.gradle

 

build.gradle에 namespace 존재 확인

 

android -> namespce 위에서 복사한것 추가함

build.gradle에 namespace 추가

 

 

다음 명령어 이후

flutter clean

flutter pub get

flutter run

 

실제 안드로이드 폰에서 정상 작동함
