What are react-native-modal-selector's main functionalities?

Basic Usage

This code demonstrates the basic usage of the react-native-modal-selector package. It shows how to create a modal selector with a list of options and handle the selection event.

import React, { useState } from 'react';
import { View, Text } from 'react-native';
import ModalSelector from 'react-native-modal-selector';

const App = () => {
  const [selectedItem, setSelectedItem] = useState('');
  const data = [
    { key: 1, label: 'Option 1' },
    { key: 2, label: 'Option 2' },
    { key: 3, label: 'Option 3' }
  ];

  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <ModalSelector
        data={data}
        initValue="Select something"
        onChange={(option) => setSelectedItem(option.label)}
      />
      <Text>Selected: {selectedItem}</Text>
    </View>
  );
};

export default App;

Custom Styling

This code demonstrates how to apply custom styling to the modal selector and its text. It shows how to use the style and selectTextStyle props to customize the appearance of the selector.

import React, { useState } from 'react';
import { View, Text, StyleSheet } from 'react-native';
import ModalSelector from 'react-native-modal-selector';

const App = () => {
  const [selectedItem, setSelectedItem] = useState('');
  const data = [
    { key: 1, label: 'Option 1' },
    { key: 2, label: 'Option 2' },
    { key: 3, label: 'Option 3' }
  ];

  return (
    <View style={styles.container}>
      <ModalSelector
        data={data}
        initValue="Select something"
        onChange={(option) => setSelectedItem(option.label)}
        style={styles.selector}
        selectTextStyle={styles.selectText}
      />
      <Text style={styles.selectedText}>Selected: {selectedItem}</Text>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center'
  },
  selector: {
    backgroundColor: '#f0f0f0',
    borderRadius: 5,
    padding: 10
  },
  selectText: {
    color: '#333'
  },
  selectedText: {
    marginTop: 20,
    fontSize: 16
  }
});

export default App;

Pre-selected Value

This code demonstrates how to set a pre-selected value in the modal selector. The initValue prop is used to specify the initial selected value.

import React, { useState } from 'react';
import { View, Text } from 'react-native';
import ModalSelector from 'react-native-modal-selector';

const App = () => {
  const [selectedItem, setSelectedItem] = useState('Option 2');
  const data = [
    { key: 1, label: 'Option 1' },
    { key: 2, label: 'Option 2' },
    { key: 3, label: 'Option 3' }
  ];

  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <ModalSelector
        data={data}
        initValue={selectedItem}
        onChange={(option) => setSelectedItem(option.label)}
      />
      <Text>Selected: {selectedItem}</Text>
    </View>
  );
};

export default App;

        this.state = {
            textInputValue: ''
        }
    }

        let index = 0;
        const data = [
            { key: index++, section: true, label: 'Fruits' },
            { key: index++, label: 'Red Apples' },
            { key: index++, label: 'Cherries' },
            { key: index++, label: 'Cranberries' },
            // etc...
            // Can also add additional custom keys which are passed to the onChange callback
            { key: index++, label: 'Vegetable', customKey: 'Not a fruit' }
        ];

        return (
            <View style={{flex:1, justifyContent:'space-around', padding:50}}>
