Flutter 환경 별 Firebase 프로젝트 설정하기 ​

Firebase 프로젝트 별칭 추가 ​

bash
# 개발 환경
firebase use --add dev
firebase use dev

# 운영 환경
firebase use --add prod
firebase use prod

.firebaserc 파일에 프로젝트 별칭이 추가 되었는지 확인

json
{
  "projects": {
    "dev": "PROJECT_ID-dev",
    "prod": "PROJECT_ID-prod"
  }
  ...
}

Firebase 프로젝트 추가 ​

1. 프로젝트 추가 ​

bash
# 개발 환경
flutterfire configure --out=lib/firebase_options_dev.dart --project=PROJECT_ID

# 운영 환경
flutterfire configure --out=lib/firebase_options_prod.dart --project=PROJECT_ID

2. Android 설정 ​

google-services.json 파일 위치 변경

text
android/
  app/
    src/
      dev/google-services.json
      prod/google-services.json

3. iOS firebase 설정 파일 위치 변경 ​

Setting GoogleService-Info.plist

  1. finder에서 dev, prod 폴더 생성하여 각 환경에 맞는 GoogleService-Info.plist 파일 위치 변경후 xCode 실행하여 Runner 폴더 하위로 드래그 앤 드롭

    text
    ios/
  Runner/
    dev/GoogleService-Info.plist
    prod/GoogleService-Info.plist

  2. 빌드 script 추가 Runner -> Build Phases -> + 버튼 클릭하여 New Run Script Phase 추가 후 아래 내용 추가 및 "Run Script"와 "Compile Sources" 사이로 순서 이동

    Setup Firebase Environment GoogleService-Info.plist

    text
     # Name of the resource we're selectively copying
 GOOGLESERVICE_INFO_PLIST=GoogleService-Info.plist

 # Get references to dev and prod versions of the GoogleService-Info.plist
 # NOTE: These should only live on the file system and should NOT be part of the target (since we'll be adding them to the target manually)
 GOOGLESERVICE_INFO_DEV=${PROJECT_DIR}/${TARGET_NAME}/dev/${GOOGLESERVICE_INFO_PLIST}
 GOOGLESERVICE_INFO_PROD=${PROJECT_DIR}/${TARGET_NAME}/prod/${GOOGLESERVICE_INFO_PLIST}

 echo "Current configutaion: ${CONFIGURATION}"

 # Make sure the dev version of GoogleService-Info.plist exists
 echo "Looking for ${GOOGLESERVICE_INFO_PLIST} in ${GOOGLESERVICE_INFO_DEV}"

 if [ ! -f $GOOGLESERVICE_INFO_DEV ]
 then
     echo "No Development GoogleService-Info.plist found. Please ensure it's in the proper directory."
     exit 1
 fi

 # Make sure the prod version of GoogleService-Info.plist exists
 echo "Looking for ${GOOGLESERVICE_INFO_PLIST} in ${GOOGLESERVICE_INFO_PROD}"

 if [ ! -f $GOOGLESERVICE_INFO_PROD ]
 then
     echo "No Production GoogleService-Info.plist found. Please ensure it's in the proper directory."
     exit 1
 fi

 # Get a reference to the destination location for the GoogleService-Info.plist
 PLIST_DESTINATION=${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.app
 echo "Will copy ${GOOGLESERVICE_INFO_PLIST} to final destination: ${PLIST_DESTINATION}"

 # Copy over the prod GoogleService-Info.plist for Release builds
 if [ "${CONFIGURATION}" == "Debug-prod" ] || [ "${CONFIGURATION}" == "Release-prod" ] || [ "${CONFIGURATION}" == "Profile-prod" ] || [ "${CONFIGURATION}" == "Release" ]
 then
     echo "Using ${GOOGLESERVICE_INFO_PROD}"
     cp "${GOOGLESERVICE_INFO_PROD}" "${PLIST_DESTINATION}"
 else
     echo "Using ${GOOGLESERVICE_INFO_DEV}"
     cp "${GOOGLESERVICE_INFO_DEV}" "${PLIST_DESTINATION}"
 fi

  3. Runner -> Build Phases -> Copy Bundle Resources에서 GoogleServices-Info.plist in Runner 삭제

4. firebase.dart 파일 내용 수정 ​

dart

  "flutter": {
    "platforms": {
      "android": {
        "dev": {
          "projectId": "PROJECT_ID_DEV",

        },
        "prod": {
          "projectId": "PROJECT_ID_PROD",
          "appId": "",

        }
      },
      "ios": {
        "dev": {
          "projectId": "PROJECT_ID_DEV",
