创建一个颤动的GetX持久BottomNaviagtionBar，并在底部栏的选项卡视图中艰难地导航到内部页面。。。
import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'package:getx_persistent_bottombar/app/routes/app_pages.dart';
import '../controllers/tab1_controller.dart';
class Tab1View extends GetView<Tab1Controller> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Tab1View'),
centerTitle: true,
),
body: Center(
child: Column(
children: [
Text(
'Tab1View is working',
style: TextStyle(fontSize: 20),
),
ElevatedButton(
onPressed: () => Get.toNamed(Routes.INTERNAL1),
child: Text("internal 1"),
),
ElevatedButton(
onPressed: () => Get.toNamed(Routes.INTERNAL2, id: 0),
child: Text("internal 2"),
),
],
),
),
);
}
}
请注意，在Get.toNamed((上传递'id'参数时，internal1首先打开，internal2打开返回错误：

那么，如何在底部栏中使用GetX和mantain来处理内部页面呢？
尝试使用构造函数传递值。它要安全得多。
