Projet Xamarin android and ios

My MainPAge.xaml.cs :

using System.ComponentModel;
using Xamarin.Forms;
using GenTurfEvo.ViewModel;
using System.Threading.Tasks;
using System;
using Rg.Plugins.Popup.Pages;
using Rg.Plugins.Popup.Services;

namespace GenTurfEvo.Views

    [DesignTimeVisible(false)]
    public partial class MainPage : ContentPage
    {
        private readonly MainPageViewModel _viewModel;
        public MainPage()
        {
            InitializeComponent();
            BindingContext = _viewModel = new MainPageViewModel();
        }
        private async void OnFrameTapped(object sender, EventArgs e)
        {
            // Afficher la popup avec le DatePicker
            await DisplayDatePickerPopup(this);
        }

        private async void OnCancelButtonClicked(object sender, EventArgs e)
        {
            await PopupNavigation.Instance.PopAsync();
        }

        private async void OnConfirmButtonClicked(object sender, EventArgs e)
        {
            // Traiter la date sélectionnée
            await PopupNavigation.Instance.PopAsync();
        }

        private async Task DisplayDatePickerPopup(MainPage mainPage)
        {
            var customDatePickerPopup = new CustomDatePickerPopup(mainPage);
            await PopupNavigation.Instance.PushAsync(customDatePickerPopup);
        }

        private class CustomDatePickerPopup : PopupPage
        {
            private readonly MainPage _mainPage;

            public CustomDatePickerPopup(MainPage mainPage)
            {
                _mainPage = mainPage;

                var datePicker = new DatePicker
                {
                    Format = "dd/MM/yyyy",
                    MaximumDate = DateTime.Now
                };

                var cancelButton = new Button { Text = "Annuler" };
                var confirmButton = new Button { Text = "Valider" };

                cancelButton.Clicked += _mainPage.OnCancelButtonClicked;
                confirmButton.Clicked += _mainPage.OnConfirmButtonClicked;

                Content = new StackLayout
                {
                    Children = { datePicker, cancelButton, confirmButton },
                    Padding = new Thickness(20)
                };
            }
        }
    }
}

My call on MainPage.xaml :

                        <!-- Date des courses -->
                        <Frame Grid.Row="0" Grid.Column="1" Margin="1,1,1,0" Padding="5,0" BackgroundColor="Green" BorderColor="Orange">
                                <Frame.GestureRecognizers>
                                    <TapGestureRecognizer Tapped="OnFrameTapped" />
                                </Frame.GestureRecognizers>
                            <Label FontSize="18" FontFamily="NunitoSemiBold" FontAttributes="Bold" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" Text="Sélectionner une date" TextColor="{StaticResource colorWhite}" />
                        </Frame>
