This tutorial shows how to send Composable as Function's Input Parameter.
● declare Function's Input Parameter as Composable myComposable: @Composable() () -> Unit
● when calling Function wrap Composable inside Lambda Complex( {Second()} )
MainActivity.kt
package com.example.myapplication
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.compose.foundation.Text
import androidx.compose.foundation.layout.*
import androidx.compose.runtime.*
import androidx.compose.ui.Modifier
import androidx.compose.ui.platform.setContent
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
Complex({Second()})
}
}
}
@Composable
fun Complex(composableInput: @Composable() () -> Unit) {
Column(Modifier.fillMaxSize()) {
Text("First")
composableInput()
}
}
@Composable fun Second() { Text("Second") }
Output
