How to make a list of objects as sharedFlow

val players: SharedFlow<List<Player>>   = MutableSharedFlow(,Player("Messi"), Player("Ronaldo"))

Is it possible to collect the changes of a list of object if one item is changed or updated?

[Charlie Christensen]

MutableSharedFlow(listOf(Player("Messi"), Player("Ronaldo")))
To update it you have to pass a new list to the shared flow

It says it requires Int as it is expecting

public fun <T> MutableSharedFlow(
    replay: Int = 0,
    extraBufferCapacity: Int = 0,
    onBufferOverflow: BufferOverflow = BufferOverflow.SUSPEND
): MutableSharedFlow<T>

[Charlie Christensen]

Oops I thought it was StateFlow

[Charlie Christensen]

You can’t pass an initial value to MutableSharedFlow

[zain]

Oh

[zain]

Can't even do this,

[zain]

val players: Flow<List<Player>> = flow { listOf(Player("Messi"), Player("Ronaldo")) }.shareIn(
        viewModelScope,
        replay = 1,
        started = SharingStarted.WhileSubscribed()
    )

[zain]

As it is shown over here,

class NewsRemoteDataSource(...,
    private val externalScope: CoroutineScope,
) {
    val latestNews: Flow<List<ArticleHeadline>> = flow {
        ...
    }.shareIn(
        externalScope,
        replay = 1,
        started = SharingStarted.WhileSubscribed()
    )
}

Not enough information to infer type variable T

[Charlie Christensen]

val players: Flow<List<Player>> = flow { 
    emit(listOf(Player("Messi"), Player("Ronaldo"))) 
}.shareIn(
        viewModelScope,
        replay = 1,
        started = SharingStarted.WhileSubscribed()
)

[Charlie Christensen]

In order to send the value to the Flow you have to emit it

Woah, any simple resource to learn flow?
