[📚] Document how to disable IDFA collection (iOS)

[wujek-srujek]

In native, it is possible to disable IDFA, see https://firebase.google.com/docs/analytics/configure-data-collection?platform=ios#disable-IDFA-collection.

At some point, this issue has been created #6030, and fixed #6046. The new switch in Podfile was first documented for 8.2.0 and last for 8.3.4 (the last version in the 8.x line). Starting with 9.0.0 up to now it is no longer documented. However, the solution still works.

Could you please add this documentation back, so that it is easier to find it? Or answer here if it is no longer recommended to use this 'without idfa' dependency?

Hello @wujek-srujek, since we migrated from the old FlutterFire documentation to the official Firebase documentation website, some part have been dropped since they would duplicate the instructions for either Android or iOS. If nothing is specified for Flutter, it means that you should use the native instructions.
Thanks for bringing this to our attention, we'll see if we can improve this.

Hi. Problem is, there is no official documentation about how to do it in Flutter. The native docs tell us to change the pod we depend on, but we typically don't do it in Flutter this way, Pod spec is created and filled out for us.
A simple mention, like it used to be on Dart Pub, would be sufficient, no idea why it disappeared.

I don't think I can, it's not my project, we have to wait for the owners. But I think you can just implement it and create a PR, looks like nobody is working on it yet.
