\n * ```\n *\n * ### Using an inline function\n * The `transition` animation method also supports reading an inline function which can decide\n * if its associated animation should be run.\n *\n * ```typescript\n * // this method is run each time the `myAnimationTrigger` trigger value changes.\n * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:\n string]: any}): boolean {\n * // notice that `element` and `params` are also available here\n * return toState == 'yes-please-animate';\n * }\n *\n * @Component({\n * selector: 'my-component',\n * templateUrl: 'my-component-tpl.html',\n * animations: [\n * trigger('myAnimationTrigger', [\n * transition(myInlineMatcherFn, [\n * // the animation sequence code\n * ]),\n * ])\n * ]\n * })\n * class MyComponent {\n * myStatusExp = \"yes-please-animate\";\n * }\n * ```\n *\n * ### Disabling Animations\n * When true, the special animation control binding `@.disabled` binding prevents\n * all animations from rendering.\n * Place the `@.disabled` binding on an element to disable\n * animations on the element itself, as well as any inner animation triggers\n * within the element.\n *\n * The following example shows how to use this feature:\n *\n * ```typescript\n * @Component({\n * selector: 'my-component',\n * template: `\n * \n * \n *
\n * `,\n * animations: [\n * trigger(\"childAnimation\", [\n * // ...\n * ])\n * ]\n * })\n * class MyComponent {\n * isDisabled = true;\n * exp = '...';\n * }\n * ```\n *\n * When `@.disabled` is true, it prevents the `@childAnimation` trigger from animating,\n * along with any inner animations.\n *\n * ### Disable animations application-wide\n * When an area of the template is set to have animations disabled,\n * **all** inner components have their animations disabled as well.\n * This means that you can disable all animations for an app\n * by placing a host binding set on `@.disabled` on the topmost Angular component.\n *\n * ```typescript\n * import {Component, HostBinding} from '@angular/core';\n *\n * @Component({\n * selector: 'app-component',\n * templateUrl: 'app.component.html',\n * })\n * class AppComponent {\n * @HostBinding('@.disabled')\n * public animationsDisabled = true;\n * }\n * ```\n *\n * ### Overriding disablement of inner animations\n * Despite inner animations being disabled, a parent animation can `query()`\n * for inner elements located in disabled areas of the template and still animate\n * them if needed. This is also the case for when a sub animation is\n * queried by a parent and then later animated using `animateChild()`.\n *\n * ### Detecting when an animation is disabled\n * If a region of the DOM (or the entire application) has its animations disabled, the animation\n * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides\n * an instance of an `AnimationEvent`. If animations are disabled,\n * the `.disabled` flag on the event is true.\n *\n * @publicApi\n */\nfunction trigger(name, definitions) {\n return { type: 7 /* AnimationMetadataType.Trigger */, name, definitions, options: {} };\n}\n/**\n * Defines an animation step that combines styling information with timing information.\n *\n * @param timings Sets `AnimateTimings` for the parent animation.\n * A string in the format \"duration [delay] [easing]\".\n * - Duration and delay are expressed as a number and optional time unit,\n * such as \"1s\" or \"10ms\" for one second and 10 milliseconds, respectively.\n * The default unit is milliseconds.\n * - The easing value controls how the animation accelerates and decelerates\n * during its runtime.

\n *\n * ### Animating to a Final State\n *\n * If the final step in a transition is a call to `animate()` that uses a timing value\n * with no `style` data, that step is automatically considered the final animation arc,\n * for the element to reach the final state, in such case Angular automatically adds or removes\n * CSS styles to ensure that the element is in the correct final state.\n *\n *\n * ### Usage Examples\n *\n * - Transition animations applied based on\n * the trigger's expression value\n *\n * ```HTML\n * \n * ...\n *
\n * ```\n *\n * ```typescript\n * trigger(\"myAnimationTrigger\", [\n * ..., // states\n * transition(\"on => off, open => closed\", animate(500)),\n * transition(\"* <=> error\", query('.indicator', animateChild()))\n * ])\n * ```\n *\n * - Transition animations applied based on custom logic dependent\n * on the trigger's expression value and provided parameters\n *\n * ```HTML\n * \n * ...\n *

For example:\n *\n * ```typescript\n * query(':self, .record:enter, .record:leave, @subTrigger', [...])\n * ```\n *\n * The `query()` function collects multiple elements and works internally by using\n * `element.querySelectorAll`. Use the `limit` field of an options object to limit\n * the total number of items to be collected. For example:\n *\n * ```js\n * query('div', [\n * animate(...),\n * animate(...)\n * ], { limit: 1 })\n * ```\n *\n * By default, throws an error when zero items are found. Set the\n * `optional` flag to ignore this error. For example:\n *\n * ```js\n * query('.some-element-that-may-not-be-there', [\n * animate(...),\n * animate(...)\n * ], { optional: true })\n * ```\n *\n * ### Entering and Leaving Elements\n *\n * Not all elements can be queried via the `:enter` and `:leave` tokens, the only ones\n * that can are those that Angular assumes can enter/leave based on their own logic\n * (if their insertion/removal is simply a consequence of that of their parent they\n * should be queried via a different token in their parent's `:enter`/`:leave` transitions).\n *\n * The only elements Angular assumes can enter/leave based on their own logic (thus the only\n * ones that can be queried via the `:enter` and `:leave` tokens) are:\n * - Those inserted dynamically (via `ViewContainerRef`)\n * - Those that have a structural directive (which, under the hood, are a subset of the above ones)\n *\n * \n *\n * Note that elements will be successfully queried via `:enter`/`:leave` even if their\n * insertion/removal is not done manually via `ViewContainerRef`or caused by their structural\n * directive (e.g. they enter/exit alongside their parent).\n *\n *
\n *\n * \n *\n * There is an exception to what previously mentioned, besides elements entering/leaving based on\n * their own logic, elements with an animation trigger can always be queried via `:leave` when\n * their parent is also leaving.\n *\n *

Since the start/end timing\n * values are collected for each property then if the current animation step is animating the same\n * property and its timing values fall anywhere into the window of time that the property is\n * currently being animated within then this is what causes an error.\n *\n * 2. Timing values\n * The validator will validate to see if a timing value of `duration delay easing` or\n * `durationNumber` is valid or not.\n *\n * (note that upon validation the code below will replace the timing data with an object containing\n * {duration,delay,easing}.\n *\n * 3.

This means\n * that when functional composition mix of these functions is evaluated (like in the example above)\n * then it will end up producing a tree of objects representing the animation itself.\n *\n * When this animation object tree is processed by the visitor code below it will visit each of the\n * verb statements within the visitor. And during each visit it will build the context of the\n * animation keyframes by interacting with the `TimelineBuilder`.\n *\n * [TimelineBuilder]\n * This class is responsible for tracking the styles and building a series of keyframe objects for a\n * timeline between a start and end time. The builder starts off with an initial timeline and each\n * time the AST comes across a `group()`, `keyframes()` or a combination of the two within a\n * `sequence()` then it will generate a sub timeline for each step as well as a new one after\n * they are complete.\n *\n * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub\n * timeline was created (based on one of the cases above) then the parent timeline will attempt to\n * merge the styles used within the sub timelines into itself (only with group() this will happen).\n * This happens with a merge operation (much like how the merge works in mergeSort) and it will only\n * copy the most recently used styles from the sub timelines into the parent timeline. This ensures\n * that if the styles are used later on in another phase of the animation then they will be the most\n * up-to-date values.\n *\n * [How Missing Styles Are Updated]\n * Each timeline has a `backFill` property which is responsible for filling in new styles into\n * already processed keyframes if a new style shows up later within the animation sequence.\n *\n * ```\n * sequence([\n * style({ width: 0 }),\n * animate(1000, style({ width: 100 })),\n * animate(1000, style({ width: 200 })),\n * animate(1000, style({ width: 300 }))\n * animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere\n * else\n * ])\n * ```\n *\n * What is happening here is that the `height` value is added later in the sequence, but is missing\n * from all previous animation steps. Therefore when a keyframe is created it would also be missing\n * from all previous keyframes up until where it is first used. For the timeline keyframe generation\n * to properly fill in the style it will place the previous value (the value from the parent\n * timeline) or a default value of `*` into the backFill map. The `copyStyles` method in util.ts\n * handles propagating that backfill map to the styles object.\n *\n * When a sub-timeline is created it will have its own backFill property.

This has important implications for animations and any stateful\n * controls that are present, such as `` elements that accept user input. Inserted rows can\n * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state\n * such as user input.\n * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).\n *\n * The identities of elements in the iterator can change while the data does not.\n * This can happen, for example, if the iterator is produced from an RPC to the server, and that\n * RPC is re-run.

You can also specify a template that is defined\n * externally, by referencing a labeled `` element. When you do this, you can\n * change which template to use at runtime, as shown in the following example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}\n *\n * ### Storing a conditional result in a variable\n *\n * You might want to show a set of properties from the same object. If you are waiting\n * for asynchronous data, the object can be undefined.\n * In this case, you can use `ngIf` and store the result of the condition in a local\n * variable as shown in the following example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfAs'}\n *\n * This code uses only one `AsyncPipe`, so only one subscription is created.\n * The conditional statement stores the result of `userStream|async` in the local variable `user`.\n * You can then bind the local `user` repeatedly.\n *\n * The conditional displays the data only if `userStream` returns a value,\n * so you don't need to use the\n * safe-navigation-operator (`?.`)\n * to guard against null values when accessing properties.\n * You can display an alternative template while waiting for the data.\n *\n * ### Shorthand syntax\n *\n * The shorthand syntax `*ngIf` expands into two separate template specifications\n * for the \"then\" and \"else\" clauses. For example, consider the following shorthand statement,\n * that is meant to show a loading page while waiting for data to be loaded.\n *\n * ```\n * \n * \n * ```\n *\n * You can see that the \"else\" clause references the ``\n * with the `#loading` label, and the template for the \"then\" clause\n * is provided as the content of the anchor element.\n *\n * However, when Angular expands the shorthand syntax, it creates\n * another `` tag, with `ngIf` and `ngIfElse` directives.\n * The anchor element containing the template for the \"then\" clause becomes\n * the content of this unlabeled `` tag.\n *\n * ```\n * \n * \n *\n * \n * \n * ```\n *\n * The presence of the implicit template object has implications for the nesting of\n * structural directives.

The URL returned by the\n * generic loader will always match the value of \"src\". In other words, this loader applies no\n * transformations to the resource URL and the value of the `ngSrc` attribute will be used as is.\n *\n * To use an existing loader for a **third-party image service**: add the provider factory for your\n * chosen service to the `providers` array. In the example below, the Imgix loader is used:\n *\n * ```typescript\n * import {provideImgixLoader} from '@angular/common';\n *\n * // Call the function and add the result to the `providers` array:\n * providers: [\n * provideImgixLoader(\"https://my.base.url/\"),\n * ],\n * ```\n *\n * The `NgOptimizedImage` directive provides the following functions:\n * - `provideCloudflareLoader`\n * - `provideCloudinaryLoader`\n * - `provideImageKitLoader`\n * - `provideImgixLoader`\n *\n * If you use a different image provider, you can create a custom loader function as described\n * below.\n *\n * To use a **custom loader**: provide your loader function as a value for the `IMAGE_LOADER` DI\n * token.\n *\n * ```typescript\n * import {IMAGE_LOADER, ImageLoaderConfig} from '@angular/common';\n *\n * // Configure the loader using the `IMAGE_LOADER` token.\n * providers: [\n * {\n * provide: IMAGE_LOADER,\n * useValue: (config: ImageLoaderConfig) => {\n * return `https://example.com/${config.src}-${config.width}.jpg}`;\n * }\n * },\n * ],\n * ```\n *\n * Step 3: update `![]()
` tags in templates to use `ngSrc` instead of `src`.\n *\n * ```\n * ![]()
