Chapter 21 and 22 Unable to import toV3Completable()

📚 Official Books Reactive Programming with Kotlin

Hello there,
I’m stucked at the last two chapter in Reactive Programming in Kotlin 2nd edition.

Currently, i’m unable to import
val taskDatabase = database ?: return
taskDatabase.taskDao().inserTasks(
listOf(
TaskItem(null,“Chapter 1: Hello, RxJava”, Date(), false),
TaskItem(null,“Chapter 2: Observables”, Date(), false),
TaskItem(null,“Chapter 3: Subjects”, Date(), false),
TaskItem(null,“Chapter 4: Observables and Subjects in practise”, Date(), false),
TaskItem(null,“Chapter 5: Filtering operators”, Date(), false),
)
).toV3Completable() ------- doesn’t import the method in my code.

I will appreciate clue and guide on how to get it resolved.
Thanks in anticipation.

I got the solution.
I was supposed to import import io.reactivex.Observable in my DAO class for the method

import statement like this

import io.reactivex.Observable

@Dao
interface TaskDao {

 @Insert
fun insertTasks(tasks:List<TaskItem>): Completable

}

@syntaxtee Glad to hear you got it! Navigating RxJavav2 types vs RxJavav3 types can be a confusing process since the names of the types are the same!
