flutter fcm 개발 시작

1.pub.dev -> firebase_message 검색

firebase_messaging: ^7.0.3

pub.dev/packages/firebase_messaging/example

firebase_messaging | Flutter Package

샘플로 동작해보니, subscribe, unsubscribe 을 눌렀을 때 동작을 하지 않는다.

 

에휴. 그래서 example 페이지에서 fireflutter를 다운받았다.

다운받아서 [flutter_message] example을 실행해 보니, 아주 잘 실행되었다..

하지만. google-services.json 을 내 환경으로 변경하니

{"message":"Internal Server Error","error":"SenderId mismatch"} 에러 발생.

 

방법을 찾으려고 github에 올려 놓았다. 과연 방법을 찾을 수 있을지.

혹시 방법을 아시는 분은 알려주시면 사례하겠습니다..

 

github 문의 사항 

 

I have compiled the following project with a sample.
Project path: ..\flutterfire\packages\firebase_messaging\firebase_messaging\example
Normal sample works normally.

Next, when the google-services.json file is changed to mine, if the following error occurs, the message will not be sent.

Please tell me how to fix it
