Configuring the app’s name, bundle identifier and copyright

The configuration for the product identifiers are centralized 
in macos/Runner/Configs/AppInfo.xcconfig. For the app’s name,
set PRODUCT_NAME, for the copyright set PRODUCT_COPYRIGHT,
and finally set PRODUCT_BUNDLE_IDENTIFIER for the app’s
bundle identifier.

Updating the app’s version number

The default version number of the app is 1.0.0.
To update it, navigate to the pubspec.yaml file
and update the following line:

version: 1.0.0+1

The version number is three numbers separated by dots,
such as 1.0.0 in the example above, followed by an optional
build number such as 1 in the example above, separated by a +.
