Shouldn't we be trying to dispose controllers for segments that no longer exist?

Yes, this may great next improvement for the code. I am not familiar with code enough to implement it. Can you create it?

Unfortunately this PR prevents a source of unnecessary allocations but creates a leak (#133949 (comment)). I suppose what needs to be done is to diff the old and new lists of segments in a https://api.flutter.dev/flutter/widgets/State/didUpdateWidget.html override and dispose the discarded segments.
