How to create click event on label in xamarin forms dynamically

Question

I am working on cross platform xamarin application and I want to create hyperlink label for "Forgot password?" on login page. I have used following code to create label but I don't know how to create onclick event on it.

 MainPage = new ContentPage
            {
                BackgroundImage = "background.png",
                Content = new StackLayout
                {
                    VerticalOptions = LayoutOptions.CenterAndExpand,
                    HorizontalOptions = LayoutOptions.CenterAndExpand,
                    Spacing = 50,
                    Children = {

                        new Label {
                            HorizontalTextAlignment = TextAlignment.Center,
                            Text = "Welcome, Please Sign in!",
                            FontSize=50,
                            TextColor=Color.Gray,
                        },


                         new Entry
                        {
                             Placeholder="Username",
                            VerticalOptions = LayoutOptions.Center,
                            Keyboard = Keyboard.Text,
                            HorizontalOptions = LayoutOptions.Center,
                             WidthRequest = 350,
                             HeightRequest = 50,
                             FontSize=20,
                             TextColor=Color.Gray,
                             PlaceholderColor=Color.Gray,
                        },

                          new Entry
                        {
                             Placeholder="Password",
                            VerticalOptions = LayoutOptions.Center,

                            Keyboard = Keyboard.Text,
                            HorizontalOptions = LayoutOptions.Center,
                             WidthRequest = 350,
                             HeightRequest = 50,
                             FontSize=25,
                             TextColor=Color.Gray,
                             IsPassword=true,
                              PlaceholderColor =Color.Gray,
                        },
                        new Button
                        {
                            Text="Login",
                            FontSize=Device.GetNamedSize(NamedSize.Large,typeof(Button)),
                            HorizontalOptions=LayoutOptions.Center,
                            VerticalOptions=LayoutOptions.Fill,
                            WidthRequest=350,
                            TextColor=Color.Silver,
                            BackgroundColor=Color.Red,
                            BorderColor=Color.Red,
                        },
                       new Label //for this label I want to create click event to open new page
                        {
                            Text="Forgot Password?",
                            FontSize=20,
                            TextColor=Color.Blue,
                            HorizontalOptions=LayoutOptions.Center,

                        },
                    } 
        }
            };

For people who prefer to use XAML and who like to bind Command directly to the ViewModel, you can use this:

<Label HorizontalOptions="Center"
       TextColor="Blue"
       FontSize="20"
       Text="Forgot Password?">
    <Label.GestureRecognizers>
        <TapGestureRecognizer Command="{Binding ForgotPasswordCommand}" />
    </Label.GestureRecognizers>
</Label>

And then in your ViewModel, you'll just assign the command to your function:

public ICommand ForgotPasswordCommand => new Command(OnForgotPassword);

And then define the function with all the work get done:

private async void OnForgotPassword()
{ ... }

PS: You will need to declare that you are using System.Windows.Input;
