Most commonly\n * it's used to animate the mounting and unmounting of a component, but can also\n * be used to describe in-place transition states as well.\n *\n * ---\n *\n * **Note**: `Transition` is a platform-agnostic base component. If you're using\n * transitions in CSS, you'll probably want to use\n * [`CSSTransition`](https://reactcommunity.org/react-transition-group/css-transition)\n * instead. It inherits all the features of `Transition`, but contains\n * additional features necessary to play nice with CSS transitions (hence the\n * name of the component).\n *\n * ---\n *\n * By default the `Transition` component does not alter the behavior of the\n * component it renders, it only tracks \"enter\" and \"exit\" states for the\n * components. It's up to you to give meaning and effect to those states. For\n * example we can add styles to a component when it enters or exits:\n *\n * ```jsx\n * import { Transition } from 'react-transition-group';\n *\n * const duration = 300;\n *\n * const defaultStyle = {\n * transition: `opacity ${duration}ms ease-in-out`,\n * opacity: 0,\n * }\n *\n * const transitionStyles = {\n * entering: { opacity: 1 },\n * entered: { opacity: 1 },\n * exiting: { opacity: 0 },\n * exited: { opacity: 0 },\n * };\n *\n * const Fade = ({ in: inProp }) => (\n * \n * {state => (\n * \n * I'm a fade Transition!\n *
\n * )}\n * \n * );\n * ```\n *\n * There are 4 main states a Transition can be in:\n * - `'entering'`\n * - `'entered'`\n * - `'exiting'`\n * - `'exited'`\n *\n * Transition state is toggled via the `in` prop. When `true` the component\n * begins the \"Enter\" stage. During this stage, the component will shift from\n * its current transition state, to `'entering'` for the duration of the\n * transition and then to the `'entered'` stage once it's complete. Let's take\n * the following example (we'll use the\n * [useState](https://reactjs.org/docs/hooks-reference.html#usestate) hook):\n *\n * ```jsx\n * function App() {\n * const [inProp, setInProp] = useState(false);\n * return (\n * \n * \n * {state => (\n * // ...\n * )}\n * \n * \n *
\n * );\n * }\n * ```\n *\n * When the button is clicked the component will shift to the `'entering'` state\n * and stay there for 500ms (the value of `timeout`) before it finally switches\n * to `'entered'`.\n *\n * When `in` is `false` the same thing happens except the state moves from\n * `'exiting'` to `'exited'`.\n */\n\nvar Transition = /*#__PURE__*/function (_React$Component) {\n _inheritsLoose(Transition, _React$Component);\n\n function Transition(props, context) {\n var _this;\n\n _this = _React$Component.call(this, props, context) || this;\n var parentGroup = context; // In the context of a TransitionGroup all enters are really appears\n\n var appear = parentGroup && !parentGroup.isMounting ? props.enter : props.appear;\n var initialStatus;\n _this.appearStatus = null;\n\n if (props.in) {\n if (appear) {\n initialStatus = EXITED;\n _this.appearStatus = ENTERING;\n } else {\n initialStatus = ENTERED;\n }\n } else {\n if (props.unmountOnExit || props.mountOnEnter) {\n initialStatus = UNMOUNTED;\n } else {\n initialStatus = EXITED;\n }\n }\n\n _this.state = {\n status: initialStatus\n };\n _this.nextCallback = null;\n return _this;\n }\n\n Transition.getDerivedStateFromProps = function getDerivedStateFromProps(_ref, prevState) {\n var nextIn = _ref.in;\n\n if (nextIn && prevState.status === UNMOUNTED) {\n return {\n status: EXITED\n };\n }\n\n return null;\n } // getSnapshotBeforeUpdate(prevProps) {\n // let nextStatus = null\n // if (prevProps !== this.props) {\n // const { status } = this.state\n // if (this.props.in) {\n // if (status !== ENTERING && status !== ENTERED) {\n // nextStatus = ENTERING\n // }\n // } else {\n // if (status === ENTERING || status === ENTERED) {\n // nextStatus = EXITING\n // }\n // }\n // }\n // return { nextStatus }\n // }\n ;\n\n var _proto = Transition.prototype;\n\n _proto.componentDidMount = function componentDidMount() {\n this.updateStatus(true, this.appearStatus);\n };\n\n _proto.componentDidUpdate = function componentDidUpdate(prevProps) {\n var nextStatus = null;\n\n if (prevProps !== this.props) {\n var status = this.state.status;\n\n if (this.props.in) {\n if (status !== ENTERING && status !== ENTERED) {\n nextStatus = ENTERING;\n }\n } else {\n if (status === ENTERING || status === ENTERED) {\n nextStatus = EXITING;\n }\n }\n }\n\n this.updateStatus(false, nextStatus);\n };\n\n _proto.componentWillUnmount = function componentWillUnmount() {\n this.cancelNextCallback();\n };\n\n _proto.getTimeouts = function getTimeouts() {\n var timeout = this.props.timeout;\n var exit, enter, appear;\n exit = enter = appear = timeout;\n\n if (timeout != null && typeof timeout !== 'number') {\n exit = timeout.exit;\n enter = timeout.enter; // TODO: remove fallback for next major\n\n appear = timeout.appear !== undefined ? timeout.appear : enter;\n }\n\n return {\n exit: exit,\n enter: enter,\n appear: appear\n };\n };\n\n _proto.updateStatus = function updateStatus(mounting, nextStatus) {\n if (mounting === void 0) {\n mounting = false;\n }\n\n if (nextStatus !== null) {\n // nextStatus will always be ENTERING or EXITING.\n this.cancelNextCallback();\n\n if (nextStatus === ENTERING) {\n if (this.props.unmountOnExit || this.props.mountOnEnter) {\n var node = this.props.nodeRef ? this.props.nodeRef.current : ReactDOM.findDOMNode(this); // https://github.com/reactjs/react-transition-group/pull/749\n // With unmountOnExit or mountOnEnter, the enter animation should happen at the transition between `exited` and `entering`.\n // To make the animation happen, we have to separate each rendering and avoid being processed as batched.\n\n if (node) forceReflow(node);\n }\n\n this.performEnter(mounting);\n } else {\n this.performExit();\n }\n } else if (this.props.unmountOnExit && this.state.status === EXITED) {\n this.setState({\n status: UNMOUNTED\n });\n }\n };\n\n _proto.performEnter = function performEnter(mounting) {\n var _this2 = this;\n\n var enter = this.props.enter;\n var appearing = this.context ? this.context.isMounting : mounting;\n\n var _ref2 = this.props.nodeRef ?
