flutter loading前一个界面关闭后一个界面的loading

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:flutter_easyloading/flutter_easyloading.dart';

class LoadingUtil {
    
    
  static showLoading(
      {
    
    bool isKeep = false,
      EasyLoadingMaskType maskType = EasyLoadingMaskType.clear,showTxt}) {
    
    
    if (EasyLoading.isShow && !isKeep) {
    
    
      EasyLoading.dismiss();
    }
    Widget? widget;
    if(showTxt != null){
    
    
      widget  = Text(showTxt,style: const TextStyle(color: Colors.white),);
    }
    EasyLoading.show(maskType: maskType,indicator: widget);
  }


  static Future<void>? dismissLoading() {
    
    
    if (EasyLoading.isShow) {
    
    
      return EasyLoading.dismiss();
    }
    return null;
  }
}

前一个界面dispose销毁，后一个界面的init显示，前一个界面居然会把后一个界面的loading关掉了，特别是三个tab切换的界面，每个界面初始化时都loading，加载数据，数据还没加载出来，上一个界面dispose的时候把下一个界面的loading关掉了，处理：那就dispose不关闭，在导航页销毁时才关闭
