Version

Tell us which versions you are using:

I am using yarn install my package.json

• react-native-router-flux 4.3.1
• react v17.0.2
• react-native v0.67.3

At first, I wrote TabBar by myself through React-native router-Flux, and then I found this problem： TypeError: undefined is not an object (evaluating '_$$_REQUIRE(_dependencyMap[31], "react-navigation-tabs").createMaterialTopTabNavigator')

Later, when I wrote TabBar according to the official Demo, this problem still appeared.

const Routers = () => ( <Router sceneStyle={styles.scene} onStateChange={stateHandler} uriPrefix={prefix} key="rootRouter">

{ console.log('Back to initial and also print this'); }} showLabel={false} tabBarStyle={styles.tabBarStyle} activeBackgroundColor="white" inactiveBackgroundColor="rgba(255, 0, 0, 0.5)"> alert('Right button')} rightTitle="Right" /> Right} /> alert('onBack button!')} hideDrawerButton backTitle="Back!" panHandlers={null} />

I fix this bug by downgrading this package :

"react-native-reanimated": "^1.7.1", "react-native-gesture-handler": "^1.6.1", "react-native-router-flux": "^4.2.0",
