Click on the Runner, click the + button, choose duplicate "Debug Configuration", and change the name to "Debug-Nightly". ![](https://874539744-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fj5JEDYzyNYZKBOeD7mDC%2Fuploads%2F50MmCwsqH2JT4WPd8Sr5%2FScreenshot%202023-03-17%20at%2011.09.20.png?alt=media\&token=7ff4418f-f6ce-41e6-a502-2f171af0056d)![](https://874539744-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fj5JEDYzyNYZKBOeD7mDC%2Fuploads%2FmxR4SKzXuQJehxLT5Nfl%2FScreenshot%202023-03-17%20at%2011.09.54.png?alt=media\&token=8f8f8a48-8b09-4111-8dbe-6749c72a17b0) 2. Create New Scheme, named "Nightly" with "target Runner". After that edit scheme with "Build Configuration" in "run, test, analyze" to "Debug-Nightly".![](https://874539744-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fj5JEDYzyNYZKBOeD7mDC%2Fuploads%2F5VHafWZj2v4pYM9WpBti%2FScreenshot%202023-03-17%20at%2011.10.09.png?alt=media\&token=845e0e9e-fcd8-434b-b4a6-ffe154a3b946)![](https://874539744-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fj5JEDYzyNYZKBOeD7mDC%2Fuploads%2FRfxQe5cLnaYaigMVmwcz%2FScreenshot%202023-03-17%20at%2011.10.30.png?alt=media\&token=efa1760f-1ccd-4227-9c91-50623c925bef)![](https://874539744-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fj5JEDYzyNYZKBOeD7mDC%2Fuploads%2FUiFd6ytoOIEEt30lGaf5%2FScreenshot%202023-03-17%20at%2011.12.26.png?alt=media\&token=5f9d2ec1-5b98-4ac0-a506-00bf66799b30) 3.

With another variable like the "Google map API" key.

This script means copying the file to the right path when we build with a flavor. 
the # Type a script or drag a script file from your workspace to insert its path.

environment="Nightly"

# Regex to extract the scheme name from the Build Configuration
# We have named our Build Configurations as Debug-Nightly, Debug-Staging, Debug-Production etc.
# Here, Nightly and Staging, Production are the scheme names. This kind of naming is required by Flutter for flavors to work.
# We are using the $CONFIGURATION variable available in the XCode build environment to extract 
# the environment (or flavor)
# For eg.
# If CONFIGURATION="Debug-Nightly", then environment will get set to "Nightly".
if [[ $CONFIGURATION =~ -([^-]*)$ ]]; then
  environment=${BASH_REMATCH[1]}

echo $environment

# Name and path of the resource we're copying

Change FLUTTER\_TARGET in User-Defined for each environment. **staging**: lib/main\_stg.dart\ **nightly**: lib/main\_nightly.dart\ **production**: lib/main\_production.dart That's all you need to do. [^1]:
