first-class support for immutable value classes is noble, the challenge is that there is a lot of existing code that either uses mutable classes or is based on immutable classes that are written and are used in chaining code style, with functions that are declared to return updated values.Mig...
In Coroutines ,a Flow is a type that can emit multiple values sequentially,as opposed to suspend functions that return only a singgle value. 在协程中,Flow是一种可以连续发出多个值的类型,而不是只返回单个值的挂起函数。 For example ,you can use a Flow to receive live updates from database. ...
