How to add multiple textfield in kivymd

i am making a form screen in which a user can input data and upload it to database. I want them to be able to add multiple textfields on a button press if they still want to add something. it should be scrollable since the amount of textfields is based on how many the user really wants. i have this code right here but it doesn't really do what i had in mind.
from kivymd.app import MDApp
from kivy.lang.builder import Builder
from kivy.uix.screenmanager import Screen
from kivy.uix.boxlayout import BoxLayout
from kivymd.uix.tab import MDTabsBase
from kivymd.uix.floatlayout import MDFloatLayout
from kivymd.uix.textfield import MDTextField
class TextField(MDTextField):
pass
class Tab(MDFloatLayout, MDTabsBase):
pass
class FormScreen(Screen):
pass
class DemoApp(MDApp):
#function to add text field
def add_textfield(self):
self.help.get_screen('form').ids.box.add_widget(
TextField(hint_text= 'adsf',
))
def upload(self):
name = self.help.get_screen('form').ids.input_1.text
def build(self):
self.help = Builder.load_file('form.kv')
# screen.add_widget(self.help)
return self.help
Here is my kv file:

Thank you

You can modify the Tab to customize the layout you need to hold all necessary fields as follows,
MDTabs:
id: tabs
background_color: rgba(0,0,0,0)
tab_hint_x: True
Tab:
title: "Passport Data"
MDBoxLayout: # Add main container.
orientation: "vertical"
padding: dp(10)
spacing: dp(5)
MDTextField:
id: input_1
hint_text: "Name"
# pos_hint: {"center_x": 0.5, "center_y": 0.95}
# size_hint: .75,0.09 # "size_hint_y" will be set automatically.
pos_hint: {"center_x": 0.5}
size_hint_x: .75
color_mode: 'accent'
mode: "rectangle"
#additional textfields
ScrollView:
MDBoxLayout: # Add all text fields in this container.
id: box
orientation: "vertical"
adaptive_height: True # Grow vertically.
Alternatively you could've inherited Tab from MDBoxLayout,
class Tab(MDBoxLayout, MDTabsBase):
pass
Then the kvlang would be,
MDTabs:
id: tabs
background_color: rgba(0,0,0,0)
tab_hint_x: True
Tab:
title: "Passport Data"
orientation: "vertical"
padding: dp(10)
spacing: dp(5)
MDTextField:
id: input_1
hint_text: "Name"
# pos_hint: {"center_x": 0.5, "center_y": 0.95}
# size_hint: .75,0.09 # "y" will be set automatically.
pos_hint: {"center_x": 0.5}
size_hint_x: .75
color_mode: 'accent'
mode: "rectangle"
#additional textfieldss
ScrollView:
MDBoxLayout: # Add all text field here.
id: box
orientation: "vertical"
adaptive_height: True # Grow vertically.

Kivy Unknown class <NavigationDrawerIconButton>

Trying kv using the example https://github.com/FranciscoCarbonell/kivymd-login-example but got `kivy.factory.FactoryException: Unknown class
Problem is in

How should I set a global variable in kivy Python?

My application is simple, the ScreenTwo is showing a form 'Parametreur' with various options to be entered.
What I'm trying to do is to set a 'save' button at the end of this form that will register into a list called 'resultat' all the options furfilled so far leaving '0' in the empty inputs.
The global variable 'resultat' would look like this ['blabla','15/06/2018','31/12/1999','6'].

Where and How should I set my global variable 'resultat' (which is a list)?
I've solved my problem but I still don't understand how does it work. Setting a variable is Kivy doesn't need to set it in the Python code. But how do Kivy and Python know about its type? Right now, it works as a list without me defining it such as (I intended it to be a list anyway).
How could I set a variable as tuple for example?

Passing information between classes in Kivy

I have a basic app in Kivy with a class for each screen. I would like to have the user enter some text in one screen and for this to be displayed in a label on another screen.
I've been through all the similar posts but can't seem to get anything working.
The two classes EnterSentences and Review have ObjectProperties. Is there a way to connect these with bind? Or do I need to just structure things completely differently?
Any help much appreciated. Here's the .py file
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.properties import ObjectProperty
class MainMenu(BoxLayout):
def enter_sentences_button(self):
self.clear_widgets()
self.add_widget(EnterSentences())
def review_button(self):
self.clear_widgets()
self.add_widget(Review())
def settings_button(self):
pass
class EnterSentences(BoxLayout):
search_box = ObjectProperty()
def main_menu(self):
self.clear_widgets()
self.add_widget(MainMenu())
class Review(BoxLayout):
sentence = ObjectProperty()
class NewApp(App):
pass
if __name__ == "__main__":
NewApp().run()
and the .kv file:
MainMenu
<MainMenu>:
orientation: 'vertical'
Label:
text: "Welcome to your Flash Card App!"
size_hint_y: 5
BoxLayout:
size_hint_y: 1
orientation: "horizontal"
Button:
text: "Enter sentences"
on_press: root.enter_sentences_button()
Button:
text: "Review"
on_press: root.review_button()
Button:
text: "Settings"
<EnterSentences>:
search_box: enter_sentence
orientation: "vertical"
Label:
text: "Enter your sentences here:"
size_hint_y: 4
TextInput:
id: enter_sentence
TextInput:
TextInput:
BoxLayout:
orientation: 'horizontal'
Button:
text: 'Main Menu'
on_press: root.main_menu()
Label:
text: ''
<Review>:
orientation: 'vertical'
Label:
size_hint_y: 4
text: root.search_box
TextInput:
size_hint_y: 1

You only have to change the kv file. You could add the text from the 3 TextInputs to 3 variables readable from the whole app:
TextInput:
+ on_text: app.sentence1=self.text
id: enter_sentence
TextInput:
+ on_text: app.sentence2=self.text
TextInput:
+ on_text: app.sentence3=self.text
Then you could access the new variables in the Review:
<Review>:
orientation: 'vertical'
Label:
size_hint_y: 4
text: app.sentence1 + "\n" + app.sentence2 + "\n" + app.sentence3
TextInput:
size_hint_y: 1
