        ],

Answer 1

怎么样？

AlertDialog(
  title: FlatButton(
    child: Text('something'),
    onPressed: () {},
  ),
);

或

AlertDialog(
  content: FlatButton(
    child: Text('something'),
    onPressed: () {},
  ),
);

Answer 2

使用CupertinoAlertDialog代替AlertDialog更加简单

CupertinoAlertDialog(
        title: Text("Alert !",
            style: AppTheme.normalTextStyle()
                .copyWith(fontWeight: FontWeight.bold, fontSize: 15)),
        content: Text(
          "Are you sure you want to logout?",
          style: AppTheme.normalTextStyle(),
        ),
        actions: <Widget>[
          FlatButton(
            child: Text("Yes", style: AppTheme.normalTextStyle()),
            onPressed: () {
              Navigator.of(context).pushAndRemoveUntil(
                  MaterialPageRoute(builder: (context) => LogInScreen()),
                  (Route<dynamic> route) => false);
            },
          ),
          FlatButton(
            child: Text("No", style: AppTheme.normalTextStyle()),
            onPressed: () {
              Navigator.of(context).pop();
            },
          )
        ],
      );
