I've built several release builds in the past but suddenly my release builds are no longer working. My debug builds are working fine. I can not determine what has changed since the last time I successfully built.
Every attempt for iOS release build lead to a similar stacktrace involving TypeFlowAnalysis.
I have a very long log but from what I can tell the crux of it is:
[ +608 ms] Persisting file store
[ +1 ms] Done persisting file store
[ +3 ms] "flutter assemble" took 2,571,290ms.

Ruling out the version of Flutter: I tried upgrading flutter to the latest stable (3.7). I tried downgrading to the version of flutter I used during the last successful release build (3.3.6).
Ruling out platform: I have the out of memory issue on iOS (stack above). Building the Android appbundle, I don't get a stacktrace but instead the system (M1 Mac 64GB) runs out of application memory.
Dependencies: Tried using the dependencies I used in the last successful release build Tried upgraded all dependencies
The usual go-to's: flutter clean, clearing XCode DerivedData, flutter pub cache clean, pod cache clean --all mentioned as solutions to similar questions found of SO.
None of the above fixed my issue.
Flutter: Exhausted heap space, trying to allocate 8589934608 bytes and laptop stops responding
^^ and other answers seem to suggest that upgrading Flutter, or cleaning Flutter will usually solve the problem with no real explanations as to why or pointing to the actual issue. These date back to 2020/21 so not sure if they are still relevant for Flutter 3+
I'm working on bisecting back to find the last known good commit but with release build taking over an hour it will take me sometime. It is a fairly large project with lots of code-gen but nothing has changed dramatically in terms of projects size since the last successful build.
Here is my flutter doctor:
