我可以在不等待 toast 结束的情况下立即更改 Toast 文本吗？

Question

在我的应用程序中，我为 activity 构建了一个 pdf 查看器小部件，当我将它滚动到上一页或下一页时，我让它敬酒并显示当前页码。

问题是，吐司需要时间显示，当我滚动足够快时，例如我滚动到页面“5”和“06”并滚动到“07”没有停顿，我必须等待“05”、“06”、“07”的吐司慢慢一一展现。

我可以立即显示特定的 Toast 而无需等待吗？

class _PdfoneState extends State<Pdfone> {
 int currentPage1 = 0;

 SharedPreferences? preferences;
 final toast = FToast();

 @override
 void initState() {
   super.initState();
   toast.init(context);
   initializePreference().whenComplete(() {
     setState(() {});
   });
 }

 @override
 Widget build(BuildContext context) {
   return Container(
       child: PDF(
     enableSwipe: true,
     pageFling: b,
     fitPolicy: FitPolicy.BOTH,
     nightMode: a,
     onPageChanged: (page, total) {
       setState(() {
         currentPage1 = page!;
         this.preferences?.setInt("page1", currentPage1);
       });
       Widget buildToast() => Container(
             padding: EdgeInsets.symmetric(vertical: 10, horizontal: 14),
             decoration: BoxDecoration(
               borderRadius: BorderRadius.circular(25),
               color: Colors.white70,
             ),
             child: Row(
               mainAxisAlignment: MainAxisAlignment.center,
               crossAxisAlignment: CrossAxisAlignment.center,
               mainAxisSize: MainAxisSize.min,
               children: [
                 Text(
                   "${page! + 1} / $total",
                   style: TextStyle(fontSize: 16),
                 )
               ],
             ),
           );
       void showToast() => toast.showToast(
             child: buildToast(),
             positionedToastBuilder: (context, child) => Positioned(
               child: child,
               top: 32,
               left: 22,
             ),
             fadeDuration: 300,
           );
       showToast();
     },

您可以清除之前的 toast 并显示当前的 toast

// To remove present shwoing toast
fToast.removeCustomToast()
 
// To clear the queue
fToast.removeQueuedCustomToasts();

void showToast(){ 
  toast.removeCustomToast(); // based on your need
  toast.removeQueuedCustomToasts();

  toast.showToast(
             child: buildToast(),
             positionedToastBuilder: (context, child) => Positioned(
               child: child,
               top: 32,
               left: 22,
             ),
             fadeDuration: 300,
           );
    }
