To collect flow in fragment/activity you should write 3 line. I wrote extension that let you collect your flow in fragment/activity in 1 line.

Kotlin flow extension

import androidx.appcompat.app.AppCompatActivity
import androidx.fragment.app.Fragment
import androidx.lifecycle.lifecycleScope
import kotlinx.coroutines.flow.Flow
import kotlinx.coroutines.flow.FlowCollector
import kotlinx.coroutines.launch

fun <T> Fragment.flowLife(flow: Flow<T>, collector: FlowCollector<T>) {
    viewLifecycleOwner.lifecycleScope.launch {
        lifecycleScope.launchWhenResumed {
            flow.collect(collector)
        }
    }
}

fun <T> Fragment.suspendFlowLife(flow: suspend () -> Flow<T>, collector: FlowCollector<T>) {
    viewLifecycleOwner.lifecycleScope.launch {
        lifecycleScope.launchWhenResumed {
            flow.invoke().collect(collector)
        }
    }
}

fun <T> AppCompatActivity.flowLife(flow: Flow<T>, collector: FlowCollector<T>) {
    this.lifecycleScope.launch {
        lifecycleScope.launchWhenResumed {
            flow.collect(collector)
        }
    }
}

fun <T> AppCompatActivity.suspendFlowLife(flow: suspend () -> Flow<T>, collector: FlowCollector<T>) {
    this.lifecycleScope.launch {
        lifecycleScope.launchWhenResumed {
            flow.invoke().collect(collector)
        }
    }
}
