Hello. What function can find the difference between collections of objects by ID?
Example:

val list1 = listOf(ExampleObject(id = 1), ExampleObject(id = 2))
val list2 = listOf(ExampleObject(id = 2))

Result: listOf(ExampleObject(1))

Thanks in advance.

I think there is a minus function

[Nikolay Puliaev]

Yes, but it isn’t compares by fields

You could union the list and distinctBy possibly

[brandonmcansh]

There is an operator that's the opposite of union just not recalling it's name

intersect
