Learning: When using ThemeProvider with reactive themes in Flowbite-Svelte, ensure that getTheme("componentName") calls are placed inside a $derived() expression (not at module scope) so components react to dynamic theme changes. This applies broadly to Svelte components in this repo that rely on theme-derived values. For example:
// bad: at module scope
const theme = getTheme("button");
// good: inside a derived store
import { derived } from 'svelte/store';
const themeDerived = derived(themeProviderStore, ($themeProvider) => getTheme("button"));
// use $themeDerived in template/component

Add missing semantic token definitions to @theme directive.
The span styling at line 43 uses custom Tailwind classes (bg-neutral-primary-medium, border-default-medium, text-heading) that are not currently defined in your src/app.css @theme block. These classes will not generate any utility styles until the corresponding CSS variables are added. Define these tokens in your @theme directive:
@theme {
/* existing tokens... */
--color-neutral-primary-medium: /* your color value */;
--border-color-default-medium: /* your color value */;
/* Add text-heading mapping if needed */

In src/lib/timeline/theme.ts around line 43 the span class uses custom semantic
tokens (bg-neutral-primary-medium, border-default-medium, text-heading) that are
not defined in the @theme directive; add corresponding CSS variable definitions
to your src/app.css @theme block — e.g. define --color-neutral-primary-medium
and --border-color-default-medium and map text-heading appropriately (or add a
semantic token alias) so Tailwind will generate the utility classes; ensure
names match exactly and provide concrete color values consistent with your
design tokens.

Restore reactive context for dynamic order updates.
The direct setContext call with the svelte-ignore comment removes reactivity. If the order prop changes after mount, child TimelineItem components won't receive the updated value.
Restore the reactive effect pattern to ensure context updates propagate:
- // svelte-ignore state_referenced_locally
- setContext<TimelineVariants["order"]>("order", order);
+ $effect(() => {
+ setContext<TimelineVariants["order"]>("order", order);
+ });This ensures that when order changes, all child components receive the updated context value.

In src/lib/timeline/Timeline.svelte around lines 11–12, the current direct
setContext call (with a svelte-ignore) breaks reactivity so updates to the order
prop won't propagate to children; replace the direct call with a reactive
statement (use Svelte's $: setContext("order", order)) so setContext runs
whenever order changes, remove the svelte-ignore, and keep the typed/context key
consistent with TimelineVariants["order"] so child TimelineItem components
receive updated values.

This doesn't work. It breaks to render unnecessary code.
There was a problem hiding this comment.
@shinokada, you're absolutely right, and I apologize for the incorrect suggestion. Using $effect to repeatedly call setContext can indeed cause rendering issues.
In Svelte 5, setContext should typically be called once at the component's initialization, not inside effects. The current implementation with the direct call is correct for this pattern.
Could you clarify: Is the order prop expected to change dynamically after the Timeline component mounts, or is it set once during initialization and remains constant? This will help me understand the intended behavior and avoid similar incorrect suggestions in the future.

Learning: In flowbite-svelte, when using ThemeProvider with reactive themes, `getTheme("componentName")` calls must be placed inside `$derived()` expressions (not at module scope) to ensure components react to dynamic theme changes. This pattern is intentional for reactive theming support.

19-19: LGTM! Prop follows existing customization pattern.The new
defaultDivClassprop allows customization of the default order marker, consistent with other*Classprops in the component.
52-57: LGTM! Correct reactive theme pattern.The
getThemecall is properly placed inside$derived()to react to dynamic theme changes, as per the learned pattern. The fallback logic fordefaultDivClsis clear and appropriate.Based on learnings, this follows the correct pattern for reactive theme integration in Flowbite-Svelte.

Verify if groupItem span styling change is intentional.
This line changes the groupItem span from plain text styling to a badge-like appearance (adds background, border, padding, and rounded corners). This is a significant visual change that affects the GroupItem component, but appears unrelated to the Timeline default order icon fix described in issue #1881.
Confirm whether this styling change is:
- Intentional and part of a broader design update, or
- Accidentally included from another branch/change
