        applicationId "com.bio.facerecognition_flutter"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
        minSdkVersion 24
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }
    ...
}
```

	CLANG_ENABLE_MODULES = YES;
	CURRENT_PROJECT_VERSION = "$(FLUTTER_BUILD_NUMBER)";
	DEVELOPMENT_TEAM = "";
	ENABLE_BITCODE = NO;
	INFOPLIST_FILE = Runner/Info.plist;
	LD_RUNPATH_SEARCH_PATHS = (
		"$(inherited)",
		"@executable_path/Frameworks",
	);
	PRODUCT_BUNDLE_IDENTIFIER = com.bio.facedemo;
	PRODUCT_NAME = "$(TARGET_NAME)";
