我在 flutter 中使用 new_vesrion ^0.3.1 包来显示警报对话框，如果 flutter 应用程序商店中有新版本可用，则显示更新应用程序，但我收到以下书面异常：

[ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: RangeError (index): Invalid value: Valid value range is empty: 1
E/flutter ( 5988): #0      List.[] (dart:core-patch/growable_array.dart:264:36)

     );
     
    final status = await newVersion.getVersionStatus();
    if(status!=null)
    { 
      if(status.canUpdate)
      {
        newVersion.showUpdateDialog
          (
            context: context, 
            versionStatus: status,
            dialogTitle: "Update!!!",
            //dismissButtonText: "Skip",
            dialogText: "Please …
