My project is react-native + expo project. I'm reproeing it on Windows.

I added expo routing, and it works well:

import { Tabs } from "expo-router";
import { Ionicons } from "@expo/vector-icons"; // Import a specific icon set

export default function TabsLayout() {
  return (
    <Tabs
      screenOptions={{
        tabBarActiveBackgroundColor: "transparent", // Ensure no active background color
        tabBarInactiveBackgroundColor: "transparent",
        tabBarActiveTintColor: "blue", // Active state color
        tabBarInactiveTintColor: "black", // Same color for inactive state
      }}
    >
      <Tabs.Screen
        name="index"
        options={{
          headerShown: false,
          tabBarLabel: "Diary",
          tabBarIcon: ({ color, size }) => (
            <Ionicons name="book-outline" color={color} size={size} />
          ),
        }}
      />
      <Tabs.Screen
        name="analytics"
        options={{
          headerShown: false,
          tabBarLabel: "Analytics",
          tabBarIcon: ({ color, size }) => (
            <Ionicons name="bar-chart-outline" color={color} size={size} />
          ),
        }}
      />
      <Tabs.Screen
        name="profile"
        options={{
          headerShown: false,
          tabBarLabel: "Profile",
          tabBarIcon: ({ color, size }) => (
            <Ionicons name="person-outline" color={color} size={size} />
          ),
        }}
      />
    </Tabs>
  );
}

For each tab item, there are 3 states:

• it is inactive (tabBarInactiveBackgroundColor is used)
• it is active (it was clicked and now selected, tabBarActiveBackgroundColor is used)
• it was pressed/clicked (around 0.5 sec there is rounded grayed rectangle on the tab item before it goes to it is active state)

My problem is that there is NO docs about how to remove this irritating grayed rectangle that appeared for 0.5 sec.

I just created the clean expo project using npx create-expo-app@latest StickerSmash from official docs, and reproed the same behavior.

Crosslinking git issue:

If anybody has ever successfully changed this background color - I would be so grateful if you tell me how.
