I created a new react-native project today (April 3rd, 2020) and added a native-base. Then I tried to add input with the floating label. It gives a warning message: Animated: useNativeDriver was not specified. This is a required option and must be explicitly set to true or false. If I removed the floating label attribute or changed it to stackedLabel the warning disappeared. While this warning is appearing, onChangeText is not being called.
Component File
import React from 'react';
import {
  SafeAreaView,
  ScrollView,
  StatusBar,
  StyleSheet,
  View,
} from 'react-native';
import {Input, Item, Label} from 'native-base';
import {Colors} from 'react-native/Libraries/NewAppScreen';
declare var global: {HermesInternal: null | {}};
const App = () => {
  return (
    <>
      <StatusBar barStyle="dark-content" />
      <SafeAreaView>
        <ScrollView
          contentInsetAdjustmentBehavior="automatic"
          style={styles.scrollView}>
          <View style={styles.body}>
            <Item floatingLabel>
              <Label>Test</Label>
              <Input onChangeText={text => console.log(text)} />
            </Item>
          </View>
        </ScrollView>
      </SafeAreaView>
    </>
  );
};
