Flutter Why this Widget should be returned as List?

6 min read

There may be several reasons why a Flutter Widget should be returned as a List, depending on the specific use case:

  1. Displaying Multiple Items: If a Widget needs to display multiple items, returning them as a List would be the most natural way. This would make it easy to add or remove items dynamically and allow for more efficient rendering.

  2. Scrollable List: If the Widget is intended to be used as a scrollable list, then returning it as a List makes sense. This would allow the user to scroll through the items and see all the content.

  3. Dynamic Data: If the data that is being displayed in the Widget is dynamic and may change frequently, returning it as a List allows for easier management and manipulation of data.

  4. Composite Widgets: If the Widget is a composite of other Widgets, returning it as a List would allow other Widgets to be added or removed easily without affecting the overall structure of the Widget.

In summary, returning a Flutter Widget as a List provides flexibility and improved performance, especially when dealing with dynamic data and complex composite Widgets.
