Description
In
CollisionPassthrough
, while searching for an ancestor withCollisionCallbacks
mixin,firstWhere
was used. This was causing it to fail when no such ancestor was found. But having a passthrough parent is not necessary, at least rest of the code wasn't designed on that assumption. So this PR replacedfirstWhere
withfirstWhereOrNull
allowing the passthrough to be null.This was discovered in one of the discord discussions.
