back button dose not close drawer on android

[msharifi99]

when the drawer is open and I want to close it by pressing back button on android's navigation bar
instead of closing the drawer, it goes back to the previous page
here's my drawerMenu code:
<Drawer type="overlay" content={<MenuContent />} tapToClose={true} openDrawerOffset={0.3} panOpenMask={0.6} tweenHandler={ratio => { return { mainOverlay: { opacity: ratio - 0.2, backgroundColor: "black" } }; }} ref={ref => (this._drawer = ref)} panCloseMask = {0.9} >
sorry for my terrible English
