What is the difference between ListView and SingleChildScrollView in Flutter?
ListView, you would use, if you have a list of UI widgets to render, and the number of such widgets is dynamic.
For example: You need to only show a list of contacts on your screen and the list items are more or less similar (UI wise and category wise). Then you would use a Listview.
A SingleChildScrollView can be compared to "ScrollView" in Android. Suppose you have a lot of UI widgets (Buttons, InputFields, Cards, etc), and they start going out of the screen. In such cases, your widgets will overflow and you will start seeing warnings. To fix this, you wrap your UI widgets with a SingleChildScrollView.
For your usecase, "Recommended" section, ListView would be a good choice.
You could consider ListView as an optimisation to the combination of SingleChildScrollView + Column.
By using ListView, only the items that are visible are mounted and painted.
On the other hand, by using SingleChildScrollView+Column, the entire item list is mounted+painted, even if only a few items are visible.
The tradeoff is that ListView is less flexible. So for complex layouts with a small number of items, the performance gain may not be worth the trouble, in which case we can use SingleChildScrollView.
ListView: is used when we have to render the same kind of widgets for n elements
SingleChildScrollView: is used when we have different widgets for n elements.
Ideally, both the cases we required scrolling, Listview have default behavior, but column and other widgets don't have so required to use
Updated: One important point you should take care while choosing ListView
ListView() -- Render all the items in the list, even if it is not visible. `ListView.Builder()` -- Render only visible items on the screen.
