Draggable List View

A custom Flutter widget that dynamically calculates item heights and supports peek-and-reveal behavior with drag-to-expand functionality. New items can be added or removed at runtime, and the list updates accordingly.

Demo

Example

Features

  • Dynamic Item Sizing:
    Measures and adjusts for items of varying heights.

  • Peek Preview:
    Shows a configurable number of last items (and an optional fraction of the next item) in collapsed state.

  • Drag-to-Reveal:
    User can drag the list up or down to reveal more items, smoothly transitioning between states.

  • Programmatic Control:
    Exposes a DraggableListController for expand(), collapse(), and end-reached callbacks via listener registration.

  • Automatic Updates:
    Handles changes to item count, peek settings, and preview fraction without losing measurements.
