How to change font size in TabBar

I am trying to change font size in <TabBar/> react native. Can someone please help me to solve this problem?

trying to change font size for this tabBar option text(All Contest, My Contest, Teams) Pages.

Here is my code:

<TabView
    navigationState={{ index, routes }}
    renderScene={renderScene}
    onIndexChange={setIndex}
    initialLayout={initialLayout}
    renderTabBar={(props) => (
      <TabBar
        {...props}
        indicatorStyle={{
          backgroundColor: "#243642",
          height: 4,
          borderTopLeftRadius: 10,
          borderTopRightRadius: 10,
        }}
        style={{
          backgroundColor: "#FFFFFF", // Background color of the tab bar
          borderBottomWidth: 1, // Bottom border for the TabBar
          borderBottomColor: "#243642", // Light border color
          shadowColor: "#000", // Shadow color for iOS
          shadowOffset: { width: 0, height: 2 }, // Shadow position
          shadowOpacity: 0.1, // Shadow opacity
          shadowRadius: 5, // Shadow radius for iOS
          elevation: 5, // Shadow effect for Android
        }}
        tabStyle={{
          paddingVertical: Platform.OS === "ios" ? 14 : 10,
        }}
        activeColor="#243642"
        inactiveColor="#387478"
      />
    )}
  />

To change font size in TabBar, you can use labelStyle prop inside your TabBar.

Refer the following code snippet to understand clearly.

<TabView
  navigationState={{ index, routes }}
  renderScene={renderScene}
  onIndexChange={setIndex}
  initialLayout={initialLayout}
  renderTabBar={(props) => (
    <TabBar
      {...props}
      indicatorStyle={{
        backgroundColor: "#243642",
        height: 4,
        borderTopLeftRadius: 10,
        borderTopRightRadius: 10,
      }}
      style={{
        backgroundColor: "#FFFFFF",
        borderBottomWidth: 1, 
        borderBottomColor: "#243642", 
        shadowColor: "#000", 
        shadowOffset: { width: 0, height: 2 }, 
        shadowOpacity: 0.1, 
        shadowRadius: 5,
        elevation: 5,
      }}
      tabStyle={{
        paddingVertical: Platform.OS === "ios" ? 14 : 10,
      }}
      labelStyle={{
        fontSize: 16, 
        fontWeight: 'bold', 
        color: '#387478',
      }}
      activeColor="#243642"
      inactiveColor="#387478"
    />
  )}
/>

Hope this helps you out :)
