Answer 1

That background color is based on the Theme , so you can change the color wrapping your PopMenuButton inside Theme and change the cardColor.

          Theme(
                data: Theme.of(context).copyWith(
                  cardColor: Colors.red,
                ),
                child: new PopupMenuButton(
                       ...

cardColor: has not worked for me , so i did it with canvasColor: – Neapolitan

I needed to change the active item's highlight color, so in my case, I used highlightColor. – Unlicensed

Answer 2

It's kinda ugly, but hey:

PopupMenuButton<String>(
   onSelected: (selected) {},
   icon: Icon(Icons.more_vert, color: Colors.white,),
   itemBuilder: (BuildContext context) {
      ...
   },
),

Answer 3

By default PopupMenuButton has a tint color.

surfaceTintColor = popupMenuTheme.shadowColor

so we also need to set its color, to make it work.

PopupMenuButton(
  color: Colors.red,
  surfaceTintColor: Colors.red,
  child: ...
),

Answer 4

You can just change the background color using PopupMenuButton( color: Colors.red, ...) without having to wrap it in a new theme.

Center(
      child: Theme(
        data: Theme.of(context).copyWith(
          cardColor: Colors.red,
        ),
        child: PopupMenuButton(
          child: Text("Show Popup Menu"),
          itemBuilder: (context) => [
                PopupMenuItem(
                  child: Text("InduceSmile.com"),
                ),
                PopupMenuItem(
                  child: Text("Flutter.io"),
                ),
                PopupMenuItem(
                  child: Text("Google.com"),
                ),
              ],
        ),
      ),

This is working fine.

Starting from Flutter 3.10, it works like this:

PopupMenuButton(
      color: Colors.red,
      child: ...
),

Answer 7

{Color? color}
Type: Color?

If provided, the background color used for the menu.

If this property is null, then [PopupMenuThemeData.color] is used. If [PopupMenuThemeData.color] is also null, then Theme.of(context).cardColor is used.

PopupMenuButton(
  color: Colors.red,
  child: ...
),
