Svelte animation blocks transition

Question

I have a component that is build like this

<ul class="space-y-3 flex-col items-end justify-end absolute bottom-6 left-6 right-6 overflow-hidden">
    {#each $chatDisplayQueue as chatEvent (chatEvent.id)}
        <div in:fly={{y:150,duration: 200}} out:fade={{duration: 200}} animate:flip={{duration: 200}}>
            <ChatMessage event={chatEvent}/>
        </div>
    {/each}
</ul>

Notice i have both a transition and an animation. The in transition works but, the out transition does not work if the flip animation is on there :/ Is there a way to do this properly so that both transitions and the animation works? Thanks in advance

Answer 1

Both animation already work, but at the same time.

When you add a delay (animation:flip={{ delay:200 }}) you're able to see the fade.

let delay = 0
function addItem() {
  delay = 0;
  ...
}
function removeItem() {
  delay = 200;
  ...
}
</script>

...
<div animation:flip={{ delay }}>...

If I understand your problem correctly you want something like this:

<script>
    import {flip} from 'svelte/animate';
    import { fly } from 'svelte/transition';
    let horizontal = false;
  let next = 1;
    let list = [];
    const addItem = () => list = [next++, ...list];
    const removeItem = number => list = list.filter(n => n !== number);
    const options = {};
</script>

<label>
  Horizontal
  <input type="checkbox" bind:checked={horizontal} />
</label>
<button on:click={addItem}>Add</button>
{#each list as n (n)}
  <div transition:fly="{{ y: 200, duration: 2000 }}" animate:flip={options} class:horizontal class="container">
      <button on:click={() => removeItem(n)}>{n}</button>
  </div>
 {/each}

<style>
    .container {
        width: fit-content; /* a fix */
    }
    .horizontal {
        display: inline-block;
        margin-left: 10px;
    }
</style>
