The report names no source file, test, or reproducible example. Start by reviewing the MDBX error handling around unexpected shutdowns on macOS with Flutter 3.24.5 and Isar 3.1.0+1, then establish a reproducible case or diagnostic evidence and add a regression test showing the transaction can be handled after power loss.
