I'm currently in the process of developing a mobile app using React Native and I've chosen to manage my navigation with React Navigation V2.
Recently, I came across some code on the official documentation that seemed perfect for what I needed:
const MainTabs = createBottomTabNavigator(
{ Home: HomeStack, Settings: SettingsStack },
{
navigationOptions: ({ navigation }: NavigationScreenProps) => ({
tabBarIcon: ({ focused, tintColor }) => {
const { routeName } = navigation.state;
let iconName;
if (routeName === "Home") {
iconName = `ios-information-circle${focused ? "" : "-outline"}`;
} else if (routeName === "Settings") {
iconName = `ios-options${focused ? "" : "-outline}`;
}
// Feel free to customize with your preferred icon component
return <Ionicons name={iconName} size={25} color={tintColor} />;
}
}),
tabBarOptions: {
activeTintColor: "tomato",
inactiveTintColor: "gray"
}
}
)
However, I encountered an unexpected error when trying to implement this code in TypeScript:
[ts]
Argument of type '{ navigationOptions: ({ navigation }: any) => { tabBarIcon: ({ focused, tintColor }: { tintColor: string | null; focused: boolean; }) => Icon; }; }' is not assignable to parameter of type 'BottomTabNavigatorConfig'.
Types of property 'navigationOptions' are incompatible.
Type '({ navigation }: any) => { tabBarIcon: ({ focused, tintColor }: { tintColor: string | null; focused: boolean; }) => Icon; }' is not assignable to type 'NavigationBottomTabScreenOptions | ((navigationOptionsContainer: NavigationScreenConfigProps & { navigationOptions: NavigationScreenProp<NavigationRoute<NavigationParams>, NavigationParams>; }) => NavigationBottomTabScreenOptions) | undefined'.
I'm puzzled as to why this error is occurring. Can anyone provide insights into what might be causing this issue?
