Xamarin.Forms elements allow you to directly query the element
to determine the state of its properties,

and is different from how you are used to.
If you have a TextFieldor a TextFormField,
you can supply a TextEditingController
to retrieve user input:

from the Flutter cookbook.

What is the equivalent of a Placeholder on an Entry?

In Xamarin.Forms, some Elements support a Placeholder property
that you can assign a value to. For example:

<Entry

Placeholder=

"This is a hint"
