https://flutter.dev/docs/deployment/flavors currently links to some community articles, but it would be better if there were official documentation.

For example, flutter/flutter#56507 is due to confusion about flavors and build configurations in Xcode. However there's no place to update and emphasize the correct fix for this issue, or even any documentation to link to. There have been some attempts to make flavors easier to use in iOS and those community articles can get out of date. There's a lot of bad advice on Stack Overflow that get people in a corrupted state.
