I have a question related with the new ElevatedButtonThemeData widget, basically I want to set the background color for all ElevatedButtons in my app, I'm struggling trying to set it up in the ThemeData definition by doing:

      theme: ThemeData(
        ...
        elevatedButtonTheme: ElevatedButtonThemeData(
            style: ButtonStyle(backgroundColor: Colors.red)), // Here Im having the error
        ...
        ),
      ),

Error:

The argument type 'MaterialColor' can't be assigned to the parameter type 'MaterialStateProperty?'.dartargument_type_not_assignable)
