Question

我是新手，无法从底部导航栏导航到新页面

我有主应用

Sub DeleteRecord()
 ActiveWindow.ScrollColumn = 2
    ActiveWindow.ScrollColumn = 5
    ActiveWindow.ScrollColumn = 7
    ActiveWindow.ScrollColumn = 9
    ActiveWindow.ScrollColumn = 11
    ActiveWindow.ScrollColumn = 16
    ActiveWindow.ScrollColumn = 20
    ActiveWindow.ScrollColumn = 22
    ActiveWindow.ScrollColumn = 23
    ActiveWindow.ScrollColumn = 24
    ActiveWindow.ScrollColumn = 25
    ActiveWindow.ScrollColumn = 27
    ActiveWindow.ScrollColumn = 29
    ActiveWindow.ScrollColumn = 30
    ActiveWindow.ScrollColumn = 31
    ActiveWindow.ScrollColumn = 32
    Dim MySheet As String
MySheet = ActiveSheet.Name


    ActiveSheet.Cells(1, 1).CurrentRegion.AutoFilter Field:=33, Criteria1:= _
    ">=-.09", Operator:=xlAnd, Criteria2:="<=.01"
      Dim cnt As Long
    cnt = Worksheets(MySheet).Cells.SpecialCells(xlCellTypeLastCell).Row

   ActiveSheet.Range("A2", ActiveCell.SpecialCells(xlLastCell)).Select
     If cnt > 3 Then
   Selection.EntireRow.Delete
End If
    ActiveWindow.ScrollColumn = 4
    ActiveWindow.ScrollColumn = 5
    ActiveWindow.ScrollColumn = 6
    ActiveWindow.ScrollColumn = 11
    ActiveWindow.ScrollColumn = 13
    ActiveWindow.ScrollColumn = 16
    ActiveWindow.ScrollColumn = 20
    ActiveWindow.ScrollColumn = 23
    ActiveWindow.ScrollColumn = 28
    ActiveWindow.ScrollColumn = 30
   ActiveSheet.Cells(1, 1).CurrentRegion.AutoFilter Field:=33
  ' Range("Claims[[#Headers],[Change in Calculated Contribution]]").Select
  Cells(1, 33).Select
    Selection.AutoFilter
End Sub

和Rootnavigator

    class MyApp extends StatelessWidget {
          @override
           Widget build(BuildContext context) {
            SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
              statusBarColor: Colors.transparent,
            ));
            return MaterialApp(
              title: 'Flutter Demo',
              theme: ThemeData(primarySwatch: Colors.blue),
              builder: (BuildContext buildContext, Widget widtget) => Scaffold(
                body: RootNavigator(),
                bottomNavigationBar: BottomNavigation(),
              ),
            );
          }
        }

和底部导航器

    class RootNavigator extends StatelessWidget {
      @override
      Widget build(BuildContext context) {
        return Navigator(
          initialRoute: '/',
          onGenerateRoute: (RouteSettings settings) {
            // final args = settings.arguments;

            return MaterialPageRoute(
                settings: settings,
                builder: (BuildContext context) {
                  switch (settings.name) {
                    case '/':
                      return Page1();
                    case '/page2':
                      return Page2();
                    case '/page3':
                      return Page3();
                    default:
                      return RouteErrorPage();
                  }
                });
              },
            );
          }
    }

标签正在切换，但路由未切换。它停留在主页上。我感觉有一些与上下文有关的东西，但不知道如何解决。有人可以帮忙吗？谢谢

p.s。如果我将底部导航栏分别移动到每个页面，除了选中的选项卡（由于状态）之外，其他所有功能都可以正常工作，而且我还想保留一个共享的应用程序栏

Answer 1

答案是-@爱评论是正确的。那就是颤动的原理。如果您具有底部导航，则必须在页面之间滑动。重定向意味着移动到全新的页面，然后您必须在sratch中定义Scaffold。如果您想共享AppBar-使其成为可重用的小部件

无法使底部导航栏和路由在抖动中协同工作
