CalendarPicker | iOS DatePicker function | Datepicker library

Ok,so for starting a javafx app,we need to launch the javafx app. Then by right if we want to add a new window we can just simply do stageobj.show(); right?

Below is part of my code,that I tried to create the new window.I already launch my app and wanted to call this new code from my app.

I make calendar for my project and need to use seved data from server inside "function CalendarPicker()". I get data from server as promise and try use it inside "function CalendarPicker()" but always get undefined. How can I force it?

so i cannot manage to get the value of any of my inputs, and the only thing is working for me is grabbing them inside render but just getting letter by letter. I want to use the same state for all of them (formData) so when I submit I can grab all the values in an unique object

Any recommendation to solve it??

I've got a CalendarPicker react-native-calendar-picker on a Modal, and it let's me select a date normally if I have nothing but a console.log(date) on it's onDateChange, but when it's function calls this.setState or this.props.changeDate, it doesn't change visually it's selection, but it logs well the new date.

Code

Constructor of the modal (child)

Goal: Be able to select 2 dates on a calendar using react-native-calendars using the onDayPress prop, and use the result in markedDates prop to form a period of days.
