using ConfigCat.Client;
using Xamarin.Forms;

namespace DemoFeatureToggle
{

    [DesignTimeVisible(false)]
    public partial class MainPage : ContentPage
    {
        public MainPage()
        {
            InitializeComponent();
            
        }

         void Handle_Clicked(object sender, System.EventArgs e)
        {
            var client = new ConfigCatClient("API KEY");
            if (client.GetValue("isAwesomeFeatureEnabled", false))
            {
                LblResult.Text = "ON";
                LblResult.TextColor = Color.GreenYellow;
            }
            else
            {
                LblResult.Text = "OFF";
                LblResult.TextColor = Color.Red;
            }
            client.Dispose();
        }
