IconButton(
  icon: Icon(_darkMode ? Icons.dark_mode : Icons.light_mode),
  onPressed: () => setState(() => _darkMode = !_darkMode),
),

The above code is in example/lib/main.dart, where Icons.dark_mode and Icons.light_mode will prompt an error:

The getter 'dark_mode' isn't defined for the type 'Icons'. Try importing the library that defines 'dark_mode', correcting the name to the name of an existing getter, or defining a getter or field named 'dark_mode'.

and I didn't find the corresponding icon in the following two sites either

It's part of the material icon font: https://fonts.google.com/icons?icon.query=dark+mode

Also, you can see the icon in the flutter framework source code; search for dark_mode in this file: https://raw.githubusercontent.com/flutter/flutter/master/packages/flutter/lib/src/material/icons.dart

Through this link, I realized that our flutter sdk has a different channel, and I also saw the added icon after switching from stable to master, thanks
