How do I open react-native's dev menu on real device

Question

I have seen already a number of border cases and strange developer interface.

From the \"shake your device\", which is really impractical, specially with a tablet

Answer 1

I add a simple absolutely positioned button and this onClick handler to it

imoprt { NativeModules } from 'react-native';
...
onMenuButtonClick(){
 NativeModules.DevMenu.show();
}
