how to remove default header in react native for stacked screen code example

Example: react native navigation remove top header screen

// This using the @react-navigation/material-top-tabs from the
// stackoverflow source...
export default class Login extends Component {
    static navigationOptions = {
        header: null
    }
}
// Didn't work for me but it did give me a clue. I ended up
// setting the header to return a basically a blank
setTimeout(() => {
    navigation.setOptions({
      header: () => (
        <View style={{ backgroundColor: "white" }}>
          <Text
            style={[
              { color: "white" },
              Platform.OS === "android" ? { fontSize: 20 } : { fontSize: 1 }
            ]}
          >
            .
          </Text>
        </View>
      )
    });
  }, 1);
// Note: in iOS sumulation, I had to tweak the initial fontSize
// to get it to not show on reload... Hence the addition of the
// setTimeout. Yes there is a blink, but now at least I don't
// have to do the tweak to start with. Not sure if this really
// works on an iOS device. Don't have a real one to test on.
