I have a mutableStateOf for a text field and a snapshotFlow version of it in my viewmodel,
How can i create a flow for typing indicator type of feature

Like when there are emissions in the snapshot flow, it should be true and when there are no emission for like 3seconds, it will be false
Again snapshot flow got new emissions, and its again true

Any idea?

Something like

snapshotFlow { textFieldValue }
    .transformLatest {
        emit(true)
        delay(3000)
        emit(false)
    }
    .distinctUntilChanged()

What if user is typing for more than 3 seconds

[Vaibhav Jaiswal]

It will drop the previous values?

When the original flow emits a new value, the previous transform block is cancelled, thus the name transformLatest.

Thankyou

One thing to note is that if you are observing a TextFieldValue , the flow will also emit when the cursor or selection position changes. If you are only interested in typing, only observe the text contents of the value.
