How to show picker on item selected in MasterPage?

Question

I installed Xamarin.Forms.InputKit in NuGet and trying to show picker on certain selected item in MasterPage.

xmlns:i18n="clr-namespace:agroNet.AppResource;assembly=agroNet"

<Picker Title="{i18n:Translate ChangeLanguage}">
    <Picker.Items>
        <x:String>Srpski</x:String>
        <x:String>Engleski</x:String>
    </Picker.Items>
</Picker>

Currently, MasterPageDetail looks like this (For now I want it to be blank):

So, on select item "Change language"

I want to show Picker, like this:

Answer 1

In MasterPage I have ListView_ItemSelected method for navigation over pages... So, solution is to add these lines in code

if (item.Id == 4)
{
    DisplayActionSheet(LocalizationResource.ChangeLanguage, "", "", LocalizationResource.SerbianLanguage, LocalizationResource.EnglishLanguage);
}

Using tihs, there is no need of any modification of xaml file.
