flutter埋点监听浏览页面

写个MyNavigatorObserver路由监听，添加到navigatorObservers:里面

import 'package:flutter/material.dart';

class MyNavigatorObserver extends NavigatorObserver {
  int count = 0;

  static List<StackBean> mStackBeans = [];
  StackBean? mStackBean;

  @override
  void didRemove(Route<dynamic> route, Route<dynamic>? previousRoute) {

  }

  @override
  void didPush(Route<dynamic> route, Route<dynamic>? previousRoute) {
    super.didPush(route, previousRoute);
    count++;
    if(mStackBean == null){
      mStackBean = StackBean();
    }
    if(route != null){
      if(route.settings.name != mStackBean!.pathName){
        mStackBeans.add(mStackBean!);
        mStackBean = StackBean();
      }
      mStackBean!.pathName = route.settings.name;
    }
    print("wgw_Observer=didPush:${route.settings.name}");
    if(previousRoute != null){
      mStackBean!.prePathName = previousRoute.settings.name;

      print("wgw_Observer=didPush:previousRoute:${previousRoute.settings.name}");
    }
    print('Total page navigations: $count');
  }

  @override
  void didPop(Route<dynamic> route, Route<dynamic>? previousRoute) {
    super.didPop(route, previousRoute);
    count--;
    if(route.settings.name == mStackBean!.pathName){
      mStackBeans.add(mStackBean!);
      mStackBean = StackBean();
    }
    print("wgw_Observer=didPop:${route.settings.name}");
    if(previousRoute != null){
      print("wgw_Observer=didPop:previousRoute:${previousRoute.settings.name}");
      if(previousRoute.settings.name == "/TabMainPage"){
        ///上传 list
        if(mStackBeans != null && mStackBeans.length>0){
          mStackBeans.forEach((element) {
            print("wgw_mStackBeans_item:${element.pathName}");
          });
        }
      }else{
        if(mStackBean == null){
          mStackBean = StackBean();
        }
        mStackBean!.pathName = previousRoute.settings.name;
      }

    }
    print('Total page navigations: $count');
  }

  @override
  void didReplace({Route<dynamic>? newRoute, Route<dynamic>? oldRoute}) {
    if(newRoute != null){
      print("wgw_Observer=didReplace:${newRoute!.settings.name}");
    }
    if(oldRoute != null){
      print("wgw_Observer=didReplace:previousRoute:${oldRoute.settings.name}");
    }
    print('Total page navigations: $count');
  }

  @override
  void didStartUserGesture(Route<dynamic> route, Route<dynamic>? previousRoute) {

  }

  @override
  void didStopUserGesture() {

  }
}

class StackBean{
  String? pathName;
  double? timeStart;
  double? timeStop;
  double? longTime;
  String? prePathName;
}

可以在其他页面进行添加和遍历清空数组上传，至于事件的上传可以埋在请求网络请求和点击事件中，单独用个结构体存放或者直接上传
