react-native-navigation: startTabBasedApp and switch to tab

Question

How can I startTabBasedApp with focused specific tab. By default it opens first tab. But I want conditionally focus tab when I startTabBasedApp

Answer 1

tabsStyle: { 
    initialTabIndex: 1, // optional, the default selected bottom tab. 
  }

Answer 2

Here's an example:

Navigation.startTabBasedApp({
     tabs: [
        {
            screen: "screen1",
            icon: require("../sharedAssets/image.png"),
            label: "label1",
        },
        {
            screen: "screen2"
            icon: require("../sharedAssets/image2.png"),
            label: "label2",
        }
    ],
    tabsStyle: {
        initialTabIndex: 1, // optional, the default selected bottom tab. Default: 0
    }
})
