在android和协程中从流中收集值的正确方法

import kotlinx.coroutines.*
import kotlinx.coroutines.flow.*

fun main() = runBlocking {
    val flow = flowOf(1, 2, 3, 4, 5) // 创建一个简单的流

    flow.collect { value ->
        println(value) // 处理流中的每个值
    }
}

import androidx.lifecycle.ViewModel
import androidx.lifecycle.viewModelScope
import kotlinx.coroutines.*
import kotlinx.coroutines.flow.*
import retrofit2.Retrofit
import retrofit2.http.GET

data class Data(val value: String)

interface ApiService {
    @GET("data")
    suspend fun getData(): List<Data>
}

class MyViewModel(private val apiService: ApiService) : ViewModel() {
    private val _dataFlow = MutableStateFlow<List<Data>>(emptyList())
    val dataFlow: StateFlow<List<Data>> = _dataFlow

    fun fetchData() {
        viewModelScope.launch {
            try {
                val data = apiService.getData()
                _dataFlow.value = data
            } catch (e: Exception) {
                // 处理异常
            }
        }
    }
}
