isMounted is deprecated when using tab views

I get this whenever I go into my tabbed scene ever since I added it. If I view the two components separately they work fine, it’s adding the tabs which cause it to break. I’ve tried various things like unmountScene={true} (pretty sure it doesn’t do anything)

Should I mute this error, because everything seems to work okay. I’m just wondering if there is something I’m doing wrong, or if this is an actual issue with the package.

    "react-native-router-flux": "^4.0.0-beta.28",
    "react-navigation": "^1.5.11",

const AppRouter = () => {
	return (
		<Router>
			<Modal key="modal">
				<Stack key="root" hideNavBar > 
					<Drawer key="Drawer" hideNavBar contentComponent={Sidebar} drawerWidth={deviceWidth/1.38}>
						<Stack key="MainStack" navBar={Layout} >
							<Scene key="Main" component={Main} />
							<Scene key="Settings" component={Settings}/>    
							<Scene key="TVInfo" component={TVInfo}/>
							<Scene key="Login" component={Login} />           
							<Scene key="TabBar" tabs={true} hideTabBar={false}>
								<Scene key="Info" hideNavBar={true} title="Info" icon={TabIcon} component={MovieInfo} />
								<Scene key="Cast" hideNavBar={true}  title="Cast" icon={TabIcon} component={Cast} />
							</Scene>
						</Stack>
					</Drawer>
				</Stack>	
			</Modal>
		</Router>
	)
}

Sorry for formatting, Markup seems to take my two space tabs as if they were like 4 or 5 spaces.

Btw, hide the warning is not a solution. I don’t consider a warning a blocker in a release, just a heads-up about possible out of date packages and future unsupported code.

Should be fixed in 0.57.
