ColumnTileSchema

Renders a Compose Column stacking its tiles vertically, spaced by arrangement and aligned horizontally by alignment. When scrollable is true the column gets a verticalScroll modifier — every child is composed eagerly, so prefer LazyColumnTileSchema for long lists.

Child scope: the column publishes its ColumnScope as a CompositionLocal (and clears the lazy-item scope), so children can use column scope modifiers such as weight.

Filtering: when filterChildrenByTerm is non-null and non-empty, only children whose searchableTerms contain that term (case-insensitive, substring match) are rendered. Children without searchableTerms are filtered out. An empty or null term renders everything.

Scroll control: the tile listens to the screen broadcast channel and reacts to scroll-to-top, scroll-to-bottom and scroll-to-offset commands addressed to its id, each optionally animated. The scroll-to variant takes a pixel offset.

Triggers dispatched:

• OnDisplayEventTrigger — fired once when the tile enters composition (keyed by tile id).

• OnClickEventTrigger — fired when the column is tapped, but only if an OnClick event is declared on this tile.

• OnLongPressEventTrigger — fired when the column is long-pressed, but only if an OnLongPress event is declared on this tile.

• OnScrolledEventTrigger — fired when the scroll direction changes, carrying ScrollDirection.Bottom when scrolling forward and ScrollDirection.Top when scrolling backward. Only meaningful when scrollable is true.
