Methods to create a conditional beans

[dant3]

Hello,

I want to create an optional bean, which should only be defined if other beans exists, or, if other bean conforms to certain condition (like it's method fun isAvailable(): Boolean returns true).

I know in theory I could make if (myCondition) { single }, but for that to work my condition has to evaluate at the moment of module evaluation. But at that time beans are not available and you cant do get() inside of your module definition. This condition evaluation should happen on a bean resolution instead.

Is this even possible with Koin? Maybe it's worth a feature request?
One of the usecases is optional beans depending on availability of certain features in your android phone. Imagine phone without simcard slot, it wont have a telephony features, thus all the related beans should not exist and be either stubbed or optional.
