FlowRow

Component in Compose Foundation Layout

[FlowRow] is a layout that fills items from left to right (ltr) in LTR layouts or right to left (rtl) in RTL layouts and when it runs out of space, moves to the next "row" or "line" positioned on the bottom, and then continues filling items until the items run out.
