Property can't be unconditionally accessed because the receiver can be null

Question

I am trying to address the null safety on the following function. Nesting if statements doesn't seem to work.

bool doesTourExceedsVenueCapacity(
  ToursRecord? tourRecord,
  int? venueCapacity,
) {
 
  return tourRecord.passengers > venueCapacity ? true : false;
}

Answer 1

Since both of your values are nullable you have to adjust your code to do the conditional check. Add some guard-like checks before:

bool doesTourExceedsVenueCapacity(
  ToursRecord? tourRecord,
  int? venueCapacity,
) {
  final passengers = tourRecord?.passengers;
  if (venueCapacity == null) return false //adjust return value
  if (passengers == null) return false // adjust return value
 
  return passengers > venueCapacity; // ? true : false unnecessary here
}
