What is the name of the shadow that appears in the scroll of the list view?

Issue

I want to change that color, becuase by default with themeData.dark() is green

Solution

If by the 'shadow', you mean this effect:

Then this effect is called overscroll glow effect, and to change it you need to change ColorScheme.secondary based on this (docs).

So it will be something like this:

Theme(
data: Theme.of(context).copyWith(
  colorScheme: ColorScheme.fromSwatch(
    accentColor: Colors.red,
  ),
),
