                          color: Colors.white,

Change value by controller _controller.text = newValue in button's on press setState() like this.

onTap: (){
setState((){
_controller.text=newValue
});
}

Try this inside onPressed method of the button

                  setState(() {
                    if (betbuttonstate[0] == false) {
                      betbuttonstate[0] = true;
                      totalbet = totalbet + betbuttonvalue[0];
                      totalmoney = totalmoney - betbuttonvalue[0];
                    } else {
                      betbuttonstate[0] = false;
                      totalbet = totalbet - betbuttonvalue[0];
                      totalmoney = totalmoney + betbuttonvalue[0];
                    }
                    _controller.text = '${formatCurrency.format(totalbet)}';

Your initState should look like this

  @override
  void initState() {
    super.initState();
    _controller =
        new TextEditingController(text: '${formatCurrency.format(totalbet)}');
  }
