Most commonly * it's used to animate the mounting and unmounting of a component, but can also * be used to describe in-place transition states as well. * * --- * * **Note**: `Transition` is a platform-agnostic base component. If you're using * transitions in CSS, you'll probably want to use * [`CSSTransition`](https://reactcommunity.org/react-transition-group/css-transition) * instead. It inherits all the features of `Transition`, but contains * additional features necessary to play nice with CSS transitions (hence the * name of the component). * * --- * * By default the `Transition` component does not alter the behavior of the * component it renders, it only tracks "enter" and "exit" states for the * components. It's up to you to give meaning and effect to those states. For * example we can add styles to a component when it enters or exits: * * ```jsx * import { Transition } from 'react-transition-group'; * * const duration = 300; * * const defaultStyle = { * transition: `opacity ${duration}ms ease-in-out`, * opacity: 0, * } * * const transitionStyles = { * entering: { opacity: 0 }, * entered: { opacity: 1 }, * }; * * const Fade = ({ in: inProp }) => ( * <Transition in={inProp} timeout={duration}> * {state => ( * <div style={{ * ...defaultStyle, * ...transitionStyles[state] * }}> * I'm a fade Transition! * </div> * )} * </Transition> * ); * ``` * * There are 4 main states a Transition can be in: * - `'entering'` * - `'entered'` * - `'exiting'` * - `'exited'` * * Transition state is toggled via the `in` prop. When `true` the component * begins the "Enter" stage. During this stage, the component will shift from * its current transition state, to `'entering'` for the duration of the * transition and then to the `'entered'` stage once it's complete. Let's take * the following example (we'll use the * [useState](https://reactjs.org/docs/hooks-reference.html#usestate) hook): * * ```jsx * function App() { * const [inProp, setInProp] = useState(false); * return ( * <div> * <Transition in={inProp} timeout={500}> * {state => ( * // ... * )} * </Transition> * <button onClick={() => setInProp(true)}> * Click to Enter * </button> * </div> * ); * } * ``` * * When the button is clicked the component will shift to the `'entering'` state * and stay there for 500ms (the value of `timeout`) before it finally switches * to `'entered'`. * * When `in` is `false` the same thing happens except the state moves from * `'exiting'` to `'exited'`. */ var Transition = /*#__PURE__*/ function (_React$Component) { _inheritsLoose(Transition, _React$Component); function Transition(props, context) { var _this; _this = _React$Component.call(this, props, context) || this; var parentGroup = context.transitionGroup; // In the context of a TransitionGroup all enters are really appears var appear = parentGroup && !parentGroup.isMounting ?
