I want use filled button

I try import material package like the official document code, But FilledButton class could not be found.

This widget not yet implemented?

[Edited]

I found a way to use FilledButton

[In terminal...]

flutter channel master
flutter pub upgrade

Then, Can find FilledButton class

No, it is not implemented yet, but you can build it with ElevatedButton like this:

ElevatedButton(
    onPressed: () {},
    child: Text("Filled"),
    style: ButtonStyle(
      minimumSize: MaterialStateProperty.all(Size(130, 40)),
      elevation: MaterialStateProperty.all(0),
      shape: MaterialStateProperty.all<RoundedRectangleBorder>(
        RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(20.0),
        ),
      ),
    ),
  ),
