I've already seen documents but I don't really understand and I want somebody to show me how to change the image of the back button in react native. enter image description here
I want to change the back arrow to a chevron or something. Could you please show me the code on how to do this?
In your StackNavigator, provide the screenOptions prop with headerBackImageSource
set to the back arrow icon or image you want.
<Stack.Navigator
initialRouteName="Home"
screenOptions={{
headerBackImageSource: `...image source...`
}}
>
The way I handle the default header of stack navigator is by creating a custom one. Every component in the main stack exports a back method so you can use it to create a event listener for your custom arrow like in the example below.
MAIN COMPONENT:
function Home({ navigation }) {
return(
<>
<CustomHeader
title="Home Page"
handleBack={() => {
navigation.goBack()
}}
/>
</>
)
}
export default Home
CUSTOM HEADER COMPONENT:
function CustomHeader(props) {
const title = props.title
const handleBack = () => {
props.handleBack()
}
return(
<View>
<Pressable
onPress={handleBack}
>
<Image
source={backArrowIcon}
resizeMode="contain"
/>
</Pressable>
<Text>
{title}
</Text>
</View>
)
}
export default CustomHeader
You just need to style that and import all the components like View, Text, CustomHeader etc.
