flutter - 如何使用 get.snackbar？

Question

每当我尝试调用 get.snackbar 时，都没有显示小吃吧？根据pub.dev页面，我只需要使用

Get.snackbar(
                  'User 123',
                  'Successfully created',
                );

但是每当我在我的代码中使用它时，没有显示 snackbar ？我用错了吗？谢谢你的帮助!

import 'package:flutter/material.dart';
import 'package:get/get.dart';

void main() {
  runApp(GetMaterialApp(    // You need to change Material App to GetMaterialApp
    home: MyApp(),
  ));
}

class MyApp extends StatefulWidget {
  @override
  _State createState() => _State();
}

class _State extends State<MyApp> {


  @override
  Widget build(BuildContext context) {
    return Scaffold(

        appBar: AppBar(
          title: Text('Flutter - Snackbar USing Get'),
        ),
        body: Center(
            child: Column(children: <Widget>[
              RaisedButton(
                textColor: Colors.white,
                color: Colors.green,
                child: Text('Show SnackBar'),
                onPressed: () {
                  Get.snackbar(
                      'User 123',
                      'Successfully created',
                      snackPosition: SnackPosition.BOTTOM
                  );
                },
              ),

            ])));
  }
}
