Thanks for fixing this! I have a suggestion to simplify this.

If we made PaywallOptions a data class would we get this for free?

Though my other suggestion might remove the need for this too.

I was trying to avoid it, since it's not recommended to expose data classes... But honestly, it's reached a point where things will be much easier, so I think I will do the change yeah.

Why is it not recommended?

Mentioned it over slack but this article has some of the drawbacks: https://jakewharton.com/public-api-challenges-in-kotlin/

| this.options = options | ||
| updateState() |

updateState only uses options.offeringSelection, so it seems silly to fetch everything if we only change something else like shouldDisplayDismissButton.
Suggestion: compare only options.offeringSelection here, but the risk is that if updateState uses something else in the future, it would break.
So to deal with that, we can extract a createState method like suspend createState(offeringSelection: OfferingSelection): PaywallState.
Then make updateState simply do:
private fun updateState() {
viewModelScope.launch {
_state.value = createState(options.offeringSelection)
}
}And we can do the exact same here, therefore ensuring that if createState ever needs more data from options, that's explicit here.
What do you think?

Actually, we also use the mode (it's masked behind a computed property in PaywallViewModelImpl), and options.shouldDisplayDismissButton in calculateState. So we would need those 3.
The other fields are the dismissRequest callback, the listener and the fontProvider... So I kinda think it's worth to just compare everything and if anything changes, just recompute the state... Wdyt?

Oh that's right. This is fine then 👍

### Description I noticed that after a configuration change (for example moving from landscape to portrait), the close button didn't work as expected on the dialogs. I tracked it down to the fact that the view model kept the first version of the dismiss callback, so it wasn't calling the new one created after the configuration change. I decided to remove the current approach of using keys to create individual view models and instead I'm adding a method to the view model that gets called every time we try to get the view model. If we detect that the PaywallOptions have changed, we will update it on the view model, ensuring we have the latest version of the callbacks.

### New Features #### ✨📱 Introducing Android Paywalls 🐾🧱 RevenueCat's Paywalls allow you to remotely configure your entire paywall view without any code changes or app updates. Our paywall templates use native code to deliver smooth, intuitive experiences to your customers when you’re ready to deliver them an Offering; and you can use our Dashboard to pick the right template and configuration to meet your needs. To use RevenueCat Paywalls on Android, simply: 1. Create a Paywall on the Dashboard for the `Offering` you intend to serve to your customers 2. Add the `RevenueCatUI` dependency to your project: ```groovy build.gradle implementation 'com.revenuecat.purchases:purchases:7.1.0' implementation 'com.revenuecat.purchases:purchases-ui:7.1.0' ``` 3. Display a paywall: ```kotlin @OptIn(ExperimentalPreviewRevenueCatUIPurchasesAPI::class) @composable private fun LockedScreen() { YourContent() PaywallDialog( PaywallDialogOptions.Builder() .setRequiredEntitlementIdentifier(Constants.ENTITLEMENT_ID) .build() ) } ``` > **Note** > Android paywalls is currently behind an experimental flag: `ExperimentalPreviewRevenueCatUIPurchasesAPI`. > It is safe to release app updates with it. We guarantee that paywalls will continue to work and any changes will always be backwards compatible. > They are stable, but migration steps may be required in the future. We'll do our best to minimize any changes you have to make.
