Loading Firebase configuration
How to load Firebase configuration files into environment variables in a Flutter workflow editor pre-build script
Instead of committing the Firebase configuration files to your repository, you can upload them to Codemagic as environment variables and reference them in a custom script. Note that the Firebase configuration file (
google-services.json for Android or
GoogleService-Info.plist for iOS) must be Base64-encoded.
- Save your Firebase config files as environment variables, e.g.
- Add the following pre-build script echoing your variables to load the Firebase configuration in Codemagic.
#!/usr/bin/env sh set -e # exit on first failed command echo $ANDROID_FIREBASE_SECRET | base64 --decode > $FCI_BUILD_DIR/android/app/google-services.json echo $IOS_FIREBASE_SECRET | base64 --decode > $FCI_BUILD_DIR/ios/Runner/GoogleService-Info.plist
In case your project is in a nested folder structure, it has to be reflected, and the script should be as follows:
#!/usr/bin/env sh set -e # exit on first failed command PROJECT_ROOT=$FCI_BUILD_DIR/myproject/path # ADD YOUR PROJECT FOLDER PATH HERE echo $ANDROID_FIREBASE_SECRET | base64 --decode > $PROJECT_ROOT/android/app/google-services.json echo $IOS_FIREBASE_SECRET | base64 --decode > $PROJECT_ROOT/ios/Runner/GoogleService-Info.plist
post-clone script failed on base64 decode. The command could not be foundIf you received this error message when using the script above, it might be due to some invisible Unicode characters in the script after copy-pasting it. Try removing the space between the
base64command and the
--decodeoption and then adding it back.
