Does `@Stable` annotation on the composable functions within the framework mean the composable functions are stable and not subject to change? Is that right ?

`@Stable` appears on types rather than on functions, and usually on interfaces rather than concrete types. At a first approximation you can think of it as saying, "this object is either `@Model` or `@Immutable`."

The contract is, if `.equals` would return `true` for this object, composition involving it can be skipped. If an object instance itself changes, it will notify the Compose runtime as appropriate.

since `foo.equals(foo)` is always true, that last part of the contract is important so that compose doesn't skip over important changes that need to be reflected.

`@Model` automatically meets this contract, and `@Immutable` does as well by declaring that an object won't change at all.

Thanks for the explanation. Now I know. At first glance I thought it mean't stable api:rolling_on_the_floor_laughing::rolling_on_the_floor_laughing:

:slightly_smiling_face: that's good feedback too, thanks!
