Naxam topTabbedpage crash on iOS at run time

Hi,
I get this error when using the plugin on iOS at run time:

I use the version 0.0.3.5
I also add the plugin MaterialControls V1.22
I add "TopTabbedRenderer.Init();" in the AppDelegate

I am not using a XAML file but a full cs file, may it be the origin of the problem ?

Ich rewrite my class using xaml

<?xml version="1.0" encoding="utf-8" ?>
<forms:TopTabbedPage  xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:android="clr-namespace:Xamarin.Forms.PlatformConfiguration.AndroidSpecific;assembly=Xamarin.Forms.Core"
    android:TabbedPage.BarSelectedItemColor ="#FE5C5C"
    xmlns:views="clr-namespace:App.Views"
    xmlns:forms="clr-namespace:Naxam.Controls.Forms;assembly=Naxam.TopTabbedPage.Forms"
    xmlns:VM="clr-namespace:App.ViewModels"
    x:Class="App.Views.SearchsView"
>
  <!--Pages can be added as references or inline-->
    <views:SearchListView Icon="calendar_icon.png" >
        <x:Arguments>
            <x:String>Agenda</x:String>
        </x:Arguments>

        <x:Arguments>

        </x:Arguments>
    </views:SearchListView>
    <views:SearchListView Icon="eye_icon.png" >
        <x:Arguments>
            <x:String>Tourism</x:String>
        </x:Arguments>
    </views:SearchListView>
    <views:SearchListView Icon="transport_health_icon.png" >
        <x:Arguments>
            <x:String>Pratique</x:String>
        </x:Arguments>
    </views:SearchListView>
</forms:TopTabbedPage>

But I still get the same error.
