Flutter Column CrossAxisAlignment.center not centering

I've been having this issue recently, When Using

    class _LoginPageState extends State<LoginPage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        crossAxisAlignment: CrossAxisAlignment.center,
        children: [
          RaisedButton(onPressed: (){}, child: Text('please'),),
          RaisedButton(onPressed: (){}, child: Text('center'),)
        ],
      ),
    );
  }
}

Results in the children widgets aligning to the left

screenshot Any help would be appreciated

This is because Column does not takes all the space available horizontally. You can do it like this :

class _LoginPageState extends State<LoginPage> {
      @override
      Widget build(BuildContext context) {
        return Scaffold(
          body: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            crossAxisAlignment: CrossAxisAlignment.center,
            children: [
             SizedBox(width : double.infinity),
              RaisedButton(onPressed: (){}, child: Text('please'),),
              RaisedButton(onPressed: (){}, child: Text('center'),)
            ],
          ),
        );
      }
    }
