React-native-tab-view: TabView inside ScrollView can not scroll vertically

[KingAmo]

# Current behaviour
rendering TabView inside ScrollView, the scene height is higher than screen height, but the ScrollView could not scroll vertically

Expected behaviour

when the content of TabView is higher than screen height, ScrollView could scroll vertivally

Code sample

import * as React from 'react';
import { View, StyleSheet, Dimensions } from 'react-native';
import { TabView, SceneMap } from 'react-native-tab-view';

const FirstRoute = () => (
  <View style={[styles.scene, { backgroundColor: '#ff4081' }]} />
);

const SecondRoute = () => (
  <View style={[styles.scene, { backgroundColor: '#673ab7' }]} />
);

const initialLayout = { width: Dimensions.get('window').width };

export default function TabViewExample() {
  const [index, setIndex] = React.useState(0);
  const [routes] = React.useState([
    { key: 'first', title: 'First' },
    { key: 'second', title: 'Second' },
  ]);

  const renderScene = SceneMap({
    first: FirstRoute,
    second: SecondRoute,
  });

  return (
    <TabView
      navigationState={{ index, routes }}
      renderScene={renderScene}
      onIndexChange={setIndex}
      initialLayout={initialLayout}
    />
  );
}

const styles = StyleSheet.create({
  scene: {
    height: 1000
  },
});

app.js

<ScrollView style={{flex: 1}} contentContainerStyle={{flex:1}}>
 <TabViewExample />
</ScrollView>

oh, i finally find what is wrong. change ScrollView's props contentContainerStyle={{flex:1}}
to contentContainerStyle={{flexGrow:1}}.
