Having a hard time understanding this newest expo bottom tabs
I dont see an initital params on the node_module for the bottomtabs or any params property... has anyone done this? essentially we have component for two bottom tabs and a different effect depending on that tab.
So 1. Can we pass Params into bottomTabs? 2. if so how?
error we get with TS is:
The expected type comes from property 'initialParams' which is declared here on type 'IntrinsicAttributes & RouteConfig<RootTabParamList, "TabThree", TabNavigationState, BottomTabNavigationOptions, BottomTabNavigationEventMap>'
<BottomTab.Screen
name="Episodes"
component={EpisodesScreen}
initialParams={{
type: "episodes",
}}
options={{
title: 'Episodes',
tabBarIcon: ({ color }) => <TabBarFeatherIcon name="headphones" color={color} />,
}}
/>
<BottomTab.Screen
name="TabThree"
component={EpisodesScreen}
initialParams={{
type: "quickGuides",
displayType: "grid",
}}
from the node_module::

export default createNavigatorFactory<

BottomTabNavigationEventMap,
typeof BottomTabNavigator
>(BottomTabNavigator);
only way i found to get my componenet to render on two different routes from the bottom tabs is to use the useNavigationState
import { useNavigationState } from "@react-navigation/native"
made a constant to check the route name and then on use effect we check the case...
const screenName = useNavigationState((state) =>
state.routes[state.index].name)
const type = screenName
useEffect(() => {
switch (type) {
case "Episodes":
setTitle("Episodes")
setIsLoading(false)
break
case "quickGuides":
setTitle("Quick Guides")
setIsLoading(false)
break
}
}, [])
