/**
 * A foundational component for inputting text into the app via a
 * keyboard. Props provide configurability for several features, such as
 * auto-correction, auto-capitalization, placeholder text, and different keyboard
 * types, such as a numeric keypad.
 *
 * The simplest use case is to plop down a `TextInput` and subscribe to the
 * `onChangeText` events to read the user input. There are also other events,
 * such as `onSubmitEditing` and `onFocus` that can be subscribed to. A simple
 * example:
 *
 * ```ReactNativeWebPlayer
 * import React, { Component } from 'react';
 * import { AppRegistry, TextInput } from 'react-native';
 *
 * export default class UselessTextInput extends Component {
 *   constructor(props) {
 *     super(props);
 *     this.state = { text: 'Useless Placeholder' };
 *   }
 *
 *   render() {
 *     return (
 *       <TextInput
 *         style={{height: 40, borderColor: 'gray', borderWidth: 1}}
 *         onChangeText={(text) => this.setState({text})}
 *         value={this.state.text}
 *       />
 *     );
 *   }
 * }
 *
 * // skip this line if using Create React Native App
 * AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);
 * ```
 *
 * Two methods exposed via the native element are .focus() and .blur() that
 * will focus or blur the TextInput programmatically.
 *
 * Note that some props are only available with `multiline={true/false}`.
 * Additionally, border styles that apply to only one side of the element
 * (e.g., `borderBottomColor`, `borderLeftWidth`, etc.) will not be applied if
 * `multiline=false`. To achieve the same effect, you can wrap your `TextInput`
 * in a `View`:
 *
 * ```ReactNativeWebPlayer
 * import React, { Component } from 'react';
 * import { AppRegistry, View, TextInput } from 'react-native';
 *
 * class UselessTextInput extends Component {
 *   render() {
 *     return (
 *       <TextInput
 *         {...this.props} // Inherit any props passed to it; e.g., multiline, numberOfLines below
 *         editable = {true}
 *         maxLength = {40}
 *       />
 *     );
 *   }
 * }
 *
 * export default class UselessTextInputMultiline extends Component {
 *   constructor(props) {
 *     super(props);
 *     this.state = {
 *       text: 'Useless Multiline Placeholder',
 *     };
 *   }
 *
 *   // If you type something in the text box that is a color, the background will change to that
 *   // color.
 *   render() {
 *     return (
 *      <View style={{
 *        backgroundColor: this.state.text,
 *        borderBottomColor: '#000000',
 *        borderBottomWidth: 1 }}
 *      >
 *        <UselessTextInput
 *          multiline = {true}
 *          numberOfLines = {4}
 *          onChangeText={(text) => this.setState({text})}
 *          value={this.state.text}
 *        />
 *      </View>
 *     );
 *   }
 * }
 *
 * // skip these lines if using Create React Native App
 * AppRegistry.registerComponent(
 *  'AwesomeProject',
 *  () => UselessTextInputMultiline
 * );
 * ```
 *
 * `TextInput` has by default a border at the bottom of its view. This border
 * has its padding set by the background image provided by the system, and it
 * cannot be changed. Solutions to avoid this is to either not set height
 * explicitly, case in which the system will take care of displaying the border
 * in the correct position, or to not display the border by setting
 * `underlineColorAndroid` to transparent.
 *
 * Note that on Android performing text selection in input can change
 * app's activity `windowSoftInputMode` param to `adjustResize`.
 * This may cause issues with components that have position: 'absolute'
 * while keyboard is active. To avoid this behavior either specify `windowSoftInputMode`
 * in AndroidManifest.xml ( https://developer.android.com/guide/topics/manifest/activity-element.html )
 * or control this param programmatically with native code.

        Hi reader from the future. I'm sorry for this.

        This is a hack. Ideally we would forwardRef to the underlying
        host component. However, since TextInput has it's own methods that can be
        called as well, if we used the standard forwardRef then these
        methods wouldn't be accessible and thus be a breaking change.

        We have a couple of options of how to handle this:
        - Return a new ref with everything we methods from both. This is problematic
          because we need React to also know it is a host component which requires
          internals of the class implementation of the ref.
        - Break the API and have some other way to call one set of the methods or
          the other. This is our long term approach as we want to eventually
          get the methods on host components off the ref. So instead of calling
          ref.measure() you might call ReactNative.measure(ref). This would hopefully
          let the ref for TextInput then have the methods like `.clear`. Or we do it
          the other way and make it TextInput.clear(textInputRef) which would be fine
          too. Either way though is a breaking change that is longer term.
        - Mutate this ref. :( Gross, but accomplishes what we need in the meantime
          before we can get to the long term breaking change.
