How to use ObservableObject and @ObservedObject with Cached objects?

[fespinoza]

Hi,

Given the following factory

protocol FeatureFlagListProtocol {
    subscript(featureFlag: FeatureFlag) -> Bool { get }
    func loadFeatureFlags() async
    func setLocalOverride(for featureFlag: FeatureFlag, isOn: Bool)
}

class DebugFeatureFlagList: FeatureFlagListProtocol {
  private var currentFlagValues: [FeatureFlag: Bool]
  //.. implementation not relevant
}

class FeatureFlagList: FeatureFlagListProtocol, ObservableObject {
  //.. implementation not relevant
}

import FactoryKit
import SwiftUI

extension Container {
    var featureFlagList: Factory<any FeatureFlagListProtocol> {
        self {
            print("---- original")
            return FeatureFlagList()
        }
        .cached
    }
}

How to use the ObservableObject as an @ObservedObject in SwiftUI

import FactoryKit

class FeatureViewModel: ObservableObject {
    @Injected(\.featureFlagList) var featureFlags // ????

    // implementation
}

The docs mention @InjectedObject that uses @StateObject under the hood.

Now, since the factory value will be cached, we don't really want to tie the object's lifecycle to the SwiftUI view that needs it.

There is no mention about this use case in the docs, hence my question.

What should I do in here?

thanks
