coroutines-guide-ui.md actor job cancellation

1

`coroutines-guide-ui.md` uses GlobalScope for scope in it's examples, e.g. in section [At most one current job](https://github.com/Kotlin/kotlinx.coroutines/blob/master/ui/coroutines-guide-ui.md#at-most-one-concurrent-job): ``` fun View.onClick(action: suspend (View) -> Unit) { // launch one actor val eventActor...

The "Extract function refactoring" section in the documentation (link [on the website](https://kotlinlang.org/docs/reference/coroutines/basics.html#extract-function-refactoring) and [in the repo](https://github.com/Kotlin/kotlinx.coroutines/blob/d55d8e80e152e46c170edc4dcfa08ccb7b2c4a03/docs/basics.md#extract-function-refactoring)) describes the process of extracting out a suspend function and makes a couple statements...

Add SharedFlow and StateFlow documentation to the Coroutines Guide

2

[`SharedFlow`](https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.flow/-shared-flow/index.html), [`StateFlow`](https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.flow/-state-flow/index.html), and their mutable counterparts have good KDoc, but they're conspicuously absent from the main https://kotlinlang.org/docs/ site. This may limit their discoverability and use. `Flow` is covered (https://kotlinlang.org/docs/flow.html), but...

SharedFlow doesn't have same parameters as in constructor function

MutableSharedFlow [**function**](https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.flow/-mutable-shared-flow.html) has three parameters: - replay: Int - extraBufferCapacity: Int - onBufferOverflow: BufferOverflow MutableSharedFlow [**interface**](https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.flow/-mutable-shared-flow/), in turn, says in its documentation that an instance can be created using this...

Stabilize flatten/flatMap family of operators

While it's still closely bound to #1147, it's worth investigating and draft-designing the original operators stabilization, so our `flatMap` analogue will be available for users who don't use any experimental...

Consider discouraging `CoroutineStart.LAZY`

1

Copying from https://github.com/Kotlin/kotlinx.coroutines/pull/4147#discussion_r1696736494: --- *How* does one use `LAZY`? Typically, in a pattern like ```kotlin // a property val optionallyRequiredValue = scope.async(start = CoroutineStart.LAZY) { // ... } ``` But...
