I downgraded from Flutter 3.14 Master with this fix to 3.13.6 Stable to debug and create production builds for API level 33 and this is now working fine. This was not just super-slow access to variables. I could NOT build at API level 33 due to SCUDO memory issues as it would always fail. Much appreciated for getting this done. |
