Pass parameters between drawer stacks react-navigation

Your problem is that your MapStack and your Map screen both have the same name, 'Map'.

Just replace the MapStack route to something else like 'MapStack' and you'll get the params.

export const DrawerStack = createDrawerNavigator(
  {
    Dashboard: { screen: DashboardStack },
    MapStack: { screen: MapStack },
  },
  {
    contentComponent: SideMenu,
    drawerWidth: 250
  }
);
