If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.

4. I tried also "apiKey = const String.fromEnvironment('$CLOUDFLARE_API_KEY',
   defaultValue: "0000");"

I have resolved the problem with the following set-up.

environment variables:
APP_CONFIG={"CLOUDFLARE_API_KEY": xxxxx}

pre-build scripts:

Create directory if it doesn't exist

mkdir -p $CM_BUILD_DIR/config

Write out the environment variable as a json file

echo $APP_CONFIG > $CM_BUILD_DIR/config/prod.json

build command flags:
--dart-define-from-file config/prod.json

How to set APP_CONFIG={"CLOUDFLARE_API_KEY": xxxxxx} in Workflow Editor ? Is APP_CONFIG a variable name on the variables tab? And where do you enter "build command flags:
--dart-define-from-file config/prod.json"
