How do I change the back button image in stack navigator in react native?

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?

>Solution :

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...`
      }}
    >
