Different behaviour between ion-tab tab attribute and ion-fab routerLink - ionic-framework

Question

I have an ionic tab page containing event specific information to display.
Routing is set up so that you are routed to a specific event's tab page
tabs.page.html
<ion-tabs>
<ion-tab-bar slot="bottom" mode="md">
<ion-tab-button tab="token">
<ion-icon src="/assets/svg/ticket-star.svg"></ion-icon>
<ion-label>Tokens</ion-label>
</ion-tab-button>
<ion-tab-button tab="transactions">
<ion-icon src="/assets/svg/empty-wallet-change.svg"></ion-icon>
<ion-label>Transactions</ion-label>
</ion-tab-button>
<div class="centerd-btn"></div>
<ion-tab-button tab="swipe">
<ion-icon src="/assets/svg/people.svg"></ion-icon>
<ion-label>Swipe</ion-label>
</ion-tab-button>
<ion-tab-button tab="buy">
<ion-icon src="/assets/svg/card.svg"></ion-icon>
<ion-label>Buy</ion-label>
</ion-tab-button>
<ion-tab-button tab="user" hidden>
</ion-tab-button>
<ion-tab-button tab="notifications" hidden>
</ion-tab-button>
<ion-tab-button tab="help" hidden>
</ion-tab-button>
</ion-tab-bar>
<ion-fab vertical="bottom" horizontal="center" slot="fixed">
<ion-fab-button routerLink="scan" routerLinkActive="active-tab" [routerLinkActiveOptions]="{exact:true}">
<ion-icon src="/assets/svg/qr-scan.svg"></ion-icon>
</ion-fab-button>
<ion-label>Scan at bar</ion-label>
</ion-fab>
</ion-tabs>
tabs-routing.module.ts
import { NgModule } from '#angular/core';
import { RouterModule, Routes } from '#angular/router';
import { TabsPage } from './tabs.page';
const routes: Routes = [
{
path: ':eventId',
component: TabsPage,
children: [
{
path: 'home',
loadChildren: () => import('../home/home.module').then(m => m.HomePageModule)
},
{
path: 'token',
loadChildren: () => import('../token/token.module').then(m => m.TokenPageModule)
},
{
path: 'transactions',
loadChildren: () => import('../transactions/transactions.module').then(m => m.TransactionsPageModule)
},
{
path: 'swipe',
loadChildren: () => import('../swipe/swipe.module').then(m => m.SwipePageModule)
},
{
path: 'buy',
loadChildren: () => import('../buy/buy.module').then(m => m.BuyPageModule)
},
{
path: 'scan',
loadChildren: () => import('../scan/scan.module').then(m => m.ScanPageModule)
},
{
path: 'notifications',
loadChildren: () => import('../notifications/notifications.module').then(m => m.NotificationsPageModule)
},
{
path: 'help',
loadChildren: () => import('../help/help.module').then(m => m.HelpPageModule)
},
{
path: 'user',
loadChildren: () => import('../user/user.module').then(m => m.UserPageModule)
},
{
path: '',
redirectTo: '/event/swipedrinks/home',
pathMatch: 'full'
}
]
},
{
path: '',
component: TabsPage
}
];
#NgModule({
imports: [RouterModule.forChild(routes)],
exports: [RouterModule]
})
export class TabsPageRoutingModule {}
All works fine except for this <ion-fab> element's routing.
I can click it the first time and the app is routed correctly to for example /event/A4OUJTpgYfeNEF6e5k4v/scan but after clicking on another tab element you can't go back to the scan part.
I don't have any console errors so I don't really know where to start.
I guess Ionic is handling the tab attribute not the same as routerLink attribute in the ion-fab element but what is the alternative then?

Hi it seems like there is some issue in sol ionic faced same issue at side nav resolved issue by using (click)="navController.naviagteForward('event/scan')" and in constructor constructor(public navController:NavController)
