Wrap the page you want to have autocomplete on with withKeyboardAwareScrollView:

import {StyleSheet, View, SafeAreaView} from "react-native";
import {Ionicons} from "@expo/vector-icons";
import shortid from "shortid";
import {Autocomplete, withKeyboardAwareScrollView} from "react-native-dropdown-autocomplete";

class HomeScreen extends Component {
  handleSelectItem(item, index) {
    const {onDropdownClose} = this.props;
    onDropdownClose();
    console.log(item);
  }

  render() {
    const autocompletes = [...Array(10).keys()];

    const apiUrl = "https://5b927fd14c818e001456e967.mockapi.io/branches";

    const {scrollToInput, onDropdownClose, onDropdownShow} = this.props;

    return (
      <View style={styles.autocompletesContainer}>
        <SafeAreaView>
          {autocompletes.map(() => (
            <Autocomplete
              key={shortid.generate()}
