I encountered a problem about kotlin Flow.When I copy the code from Official guide,the Android Studio prompts an error "No type arguments expected for class Flow".Does anyone know why？ Thanks for answering .

 fun simple(): Flow<Int> = flow { 
        for (i in 1..3) {
            delay(100) 
            emit(i) 
        }
    }

Make sure you use import kotlinx.coroutines.flow.Flow not java.util.concurrent.Flow, it gives you this error because Java concurrent Flow class take 0 type arguments, but Coroutines Flow take one
