I am using Dagger2 for DI in my Android app, and using this code for injecting classes into my Activity is fine:
@field:[Inject ApplicationContext]
lateinit var context: Context
but, lateinit modifier is not allowed on primitive type properties in Kotlin (for instance Boolean), how can I do something like this?
@field:[Inject Named("isDemo")]
lateinit var isDemo: Boolean
when I remove lateinit from this code I get this error Dagger does not support injection into private fields
First, you don't need lateinit, you can leave it as a var, and initialize with an arbitrary value.
Second, you must expose a field in order to allow Dagger to inject there.
So, here's the solution:
@JvmField // expose a field
@field:[Inject Named("isDemo")] // leave your annotatios unchanged
var isDemo: Boolean = false // set a default value
Maybe you should think of a
protectedtrue if you want to protect your property to be accessed (and changed) just in (sub-)classes - works with Dagger because this won't result inprivateThis works. Thanks. This is some mess. Hope dagger/kotlin solves this.
