Is there a way to clear all tab stacks when switching tabs in Ionic?

Currently, my tab code stacks all pages on top of each other for separate tabs. This results in showing previous stacked pages when I switch tabs, but I want all tabs to go back to the root page when changing tabs. Below is my existing code:

export class TabsPage {

  tab1Root = HomePage;
  tab2Root = SearchPage;
  tab3Root = QueuesPage;
  tab4Root = FavoritesPage;
  tab5Root = SettingsPage;

  constructor() {

  }
}
<ion-tabs>
  <ion-tab [root]="tab1Root" tabTitle="Home" tabIcon="home"></ion-tab>
  <ion-tab [root]="tab2Root" tabTitle="Search" tabIcon="search"></ion-tab>
  <ion-tab [root]="tab3Root" tabTitle="Queues" tabIcon="people"></ion-tab>
  <ion-tab [root]="tab4Root" tabTitle="Favorites" tabIcon="star"></ion-tab>
  <ion-tab [root]="tab5Root" tabTitle="Settings" tabIcon="cog"></ion-tab>
</ion-tabs>

Answer №1

To achieve the desired outcome, I successfully obtained the reference of the tabs component and accessed the NavController from the previous tab in order to utilize the popToRoot() method:

<!-- #myTabs allows us to obtain a reference of the tabs -->
<!-- (ionChange) enables us to execute our method whenever the selected tab is changed -->
<ion-tabs #myTabs (ionChange)="onTabsChange()">
  <ion-tab [root]="tab1Root" tabTitle="Home" tabIcon="home"></ion-tab>
  <ion-tab [root]="tab2Root" tabTitle="About" tabIcon="information-circle"></ion-tab>
  <ion-tab [root]="tab3Root" tabTitle="Contact" tabIcon="contacts"></ion-tab>
</ion-tabs>

Subsequently:

// Angular
import { Component, ViewChild } from '@angular/core';

// Pages
import { AboutPage } from '../about/about';
import { ContactPage } from '../contact/contact';
import { HomePage } from '../home/home';

// Tabs
import { Tabs } from 'ionic-angular';

@Component({
  templateUrl: 'tabs.html'
})
export class TabsPage {

  @ViewChild('myTabs') tabRef: Tabs;

  tab1Root = HomePage;
  tab2Root = AboutPage;
  tab3Root = ContactPage;

  onTabsChange() {
    // Retrieve the preceding tab if available
    const previousTab = this.tabRef.previousTab(false);

    if(previousTab) {
      try {
        // Obtain the navCtrl and navigate back to the root page
        previousTab.getViews()[0].getNav().popToRoot();
      } catch(exception) {
        // Handle potential errors
        console.error(exception);
      }
    }
  }
}

After exploring various options for Ionic 4/5, I stumbled upon a unique solution that perfectly addressed my needs:

By incorporating the tab and routerLink within the <ion-tab-button> element, I was able to achieve seamless navigation without resorting to eventHandlers, navControllers, or lifecycle management:

<ion-tab-button class="dashboard__button" tab="beneficiaries" routerLink="/dashboard/beneficiaries">

This approach ensured that each time I navigated back to the tab, it consistently loaded the root page.
