Can't change background color of keyPad ("keyPadColor"-property does nothing)

[stiltet]

There is no way to change the background color of the round number keys. There is a property setting called "keyPadColor" that I suspect is intended for this purpose following the documentation, but it does nothing when I change this value.

Source Code:

@override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( backgroundColor: Colors.white, body: SafeArea( child: Column( children: <Widget>[ SizedBox( height: 140, ), DialPad( keyPadTextColor: Colors.black, keyPadColor: Colors.red, // outputMask: //Visual formatting of input // "0000 000 00 00", //Here you can mask the display of inserted number. unformatted text won't show up. dialButtonColor: Colors.green, dialButtonIconColor: Colors.white, buttonIcon: FontAwesome.phone, enableDtmf: false, // Don't work in Android Emulator. backspaceButtonIconColor: Colors.red, useNumber: (number) { //use this number variable for any reference or implementation. print(number); }), ], ), ), ), ); }

Result:
