I want to use a event bus in my project. I use kotlin and coroutines but I don't use Rx. Can you recommend me what event bus to use or a good approach?

[gildor]

Opinion: Good event bus is no event bus

[ruialonso]

no event bus

[rkeazor]

No event bus😂😂

[rkeazor]

People shouldnt be talking about eventbus in 2019😂😂

[gildor]

Actual answer depends on your use case of course, maybe you could provide what you want to achieve with event bus

[dakinne]

The app has a bottom navigation bar.
One option start a new activity with a form for create products, and another option show a list of products. In the list of products I can tap on a product for see the detail.
If I stay in a product detail and I tap on first option the createProductActivity is started. When the product is created I need to refresh de list of product. How can I do it?
[I'm spanish, sorry for my english]

[ruialonso]

your view can observe a Livedata of productList that is modified by CreateProductUseCase in a coroutine

[ruialonso]

to avoid bifurcation on success/error your Livedata could be an Either of productList

[rkeazor]

Yea observing a livedata object would work fine

[gildor]

Or Flow

lol

[gildor]

Yes Robert, I thought about you when wrote my message 😅

[rkeazor]

The problem with EventBus, is that its one hard to understand the flow of control in the application. Two its weird to tests(if you have tests)

[ruialonso]

event bus is not sequential, so you lost flow. Besides needed to much events for success and error

[rkeazor]

EventBus was good during a time when the Android Framework wasn't very friendly. But its been many years since than, and the ecosystem has grown.
