	return(
    	<View>
      		<Text>{title}</View>
      	</View>
    )
}

2. navigation

const Navigation = () => {

return(
	<NavigationContainer>
  		<Stack.Navigator>
  			<Stack.Screen name="Main" component={MainComponent}
				options={{
                        	header: () => <CustomHeader title="메인"/>
                        }}
