i’ve got a class like:

class MyFoo(
    val title:  String,
    val client: Foo = (some default)
) {...}

I want to provide a default value of Foo when if it’s not provided, but it’s nontrivial to create a valid instance, and requires storing an instance variable e.g.

val x = Bar()
client = Foo.builder().bar(x).baz(Baz.builder().bar(x).build()).build()

i’m struggling to figure out if this is possible with initializer / secondary constructors, without having to make client a nullable var.

[ephemient]

class MyFoo(
    val title: String,
    val client = run {
        val x = Bar()
        Foo.builder().bar(x).Baz(Baz.builder().bar(x).build()).build()
    }
)

should work, but for something as complex you should probably have a fun defaultClient(title: String): Foo instead

[sbyrne]

The default can come from a method call: e.g.: val client:Foo = getDefaultClient(), which could be a method in Foo's companion object, or anywhere else.

ah, welp, that makes sense

dunno how on earth i didn’t get to that myself, but… thanks!
