Add widget dynamically from outside class (error)

I´m learning kivy, and it has passed 3 weeks since i face this problem without encounter a solution, so i hope any of u guys could help me, i would appreciate it.
I have a main file:
from app import MyProgramApp
if __name__ == "__main__":
winapp = MyProgramApp()
winapp.run()
from where i start my app. Then i have a directory called "app", inside there is the following "init.py" file.
from kivy.app import App
from kivy.utils import QueryDict, rgba
from kivy.core.window import Window
from .view import MainWindow
Window.minimum_width = 500
Window.minimum_height = 650
Window.maximize()
class MyProgramApp(App):
colors = QueryDict()
colors.primary = rgba('#2D9CDB')
colors.secondary = rgba('#16213E')
colors.succes = rgba('#1FC98E')
colors.warning = rgba('#F2C94C')
colors.danger = rgba('#E85757')
colors.grey_dark = rgba('#C4C4C4')
colors.grey_light = rgba('#F5F5F5')
colors.black = rgba('#A1A1A1')
colors.white = rgba('#FFFFFF')
def build(self):
return MainWindow()
Same folder app, i have the following "view.py".
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.behaviors import ToggleButtonBehavior
from kivy.properties import StringProperty
from kivy.uix.screenmanager import ScreenManager
class MainWindow(BoxLayout):
username = StringProperty("Usuario")
def __init__(self, **kw):
super().__init__(**kw)
def on_press_home(self):
self.ids.scrn_mngr.current = "scrn_home"
class ViewManager(ScreenManager):
def __init__(self, **kw):
super().__init__(**kw)
class NavTab(ToggleButtonBehavior, BoxLayout):
text = StringProperty('')
icon = StringProperty('')
def __init__(self, **kw):
super().__init__(**kw)
and finally for that folder i have "myprogram.kv"

Then i got another folder called "views" inside i have another folder called "home", inside home we encounter 3 files "init.py", "home.kv", "home.py". the first one "init.py" is the following.
from .home import Home
then we got "home.kv".

Label:
text: "Some text"
Button:
text: "create buttons on box"
on_press: root.modify_home_box()
and finally and the problem that i´m facing is whit the following file "home.py"
from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivy.factory import Factory
from kivy.uix.popup import Popup
from kivy.uix.button import Button
from kivy.app import App
Builder.load_file('views/home/home.kv')
class Home(BoxLayout):
def __init__(self, **kwargs):
super().__init__(**kwargs)
def open_popup(self):
Factory.SomePopup().open()
class SomePopup(Popup):
def __init__(self, **kw):
super().__init__(**kw)
def modify_home_box(self):
my_app = App.get_running_app().root
my_box = my_app.ids.home.ids.home_box
custom_button = Button(
text = "something"
)
my_box.add_widget(custom_button)
That i´m trying to do is actually modify "home_box" with is store on ids Home dictionary, i also try with ObjectProperty (but that gives and Attribute Error, since i only could read propertys but doesnt modify it), instance of a new Home class doesnt work... searching for current app in App appear doesnt work since Home is store i think on screenManager...
I need add a button or some widget to "home_box" from outside class "SomePopup". I also drop here a repository on github with the whole code. github_repo
I don't know how to solve my issue, and i try with the resources available here on stack as well other net places... any help would be appreciate.

Just a very complicated path to the widget of interest. In your modify_home_box() method, try replacing:
my_app = App.get_running_app().root
my_box = my_app.ids.home.ids.home_box
with:
my_app = App.get_running_app().root
my_box = my_app.ids.scrn_mngr.ids.home.ids.home_box

KivyMD MDRectangleFlatIconButton's text is in two lines when text is updated with a long text

I want to update MDRectangleFlatIconButton's text. It changes with a new text but when the new text is longer than previous text, then the text fits in two lines.
When i use a normal button, the new text fits in one line with proper adjustment.
but Since there is a Icon in MDRectangleFlatIconButton, when a new text is longer than previous text, the text fits in a two line.
To run the program,
Add a new app name which is longer than "Info" inside "Info" button's popup window, then click "Update Top Bar's name". Then, it updated title and the text of "Info" button at the front main App.
I have tried to change this by adding button's text_size: self.width, valign:"center", haling: "center", or manually adding text_size: cm(10), cm(10).
Also, i tried with on_release: "app.root.ids.bt_information.text_size = self.width, None
but nothing works so far.
I greatly appreciate your help.

I already tried to search on kivy's documentation and here on the site, but not something helpful.

Spinner, ToggleButton store value and print when pressing Button

I'm pretty new to python and kivy and I'm trying to build my first app for my masterthesis. The problem I'm struggeling with right now is that I have multiple python and kivy files, and my app includes a group of Toggle buttons and Spinners. I want to 'store'/assign theselected values and print them when i hit my submit button. I'm working with multiple python and kivy files. The app also has some sliders and i managed to get those values when pressing submit, but can't figure it out for toggles nor spinners. I hope you can help!:)
Main .py, rather important:

Builder.load_file('Outputparameters.kv')
#Layout

#class InputParameters(BoxLayout):

class PeenomatApp(App):
def build(self):
return Peenomat()
if __name__=="__main__":
PeenomatApp().run()
The main kv file:

np.material.text = "Auswahl treffen"
np.haerte.value = 55
np.rauheit.value = 5.5
The App is running like this and the clear button is exactly doing what its supposed to do, but I really can't figure out how I manage to print the selected spinner and toggle values when hitting submit...I hope you guys can help, been struggeling with this since a while now. Thanks in advance!

Alright i figured out an easy way to get the spinner value when hititng submit:
def btn_submit(self):
ip = App.get_running_app().root.ids._input_parameters
print("Haerte:", ip.haerte.value, "Rauheit:", ip.rauheit.value, "Material:", ip.material.text, "Vorbehandlung:", ip.vorbehandlung.text)
to get the value of the toggle buttons i did this:
def on_state(self, togglebutton):
tb = togglebutton
if tb.state == 'down':
self.verfahren = tb.text
InputParameters.verfahren = tb.text
print(self.verfahren)
return InputParameters.verfahren
and added in the .kv file for the toggle button:
ToggleButton:
id:_prozess2
text:'E-MOH'
on_state: root.on_state(self)
I'm getting the value/state like that, but it's not triggered with the submit button, can't figure out how to do so

Drag and Drop image and display image on gridlayout - Kivy

I'm new to kivy and I'm trying to create a drag and drop app where if the image is dropped onto the gridlayout the image is shown on the app as shown below. I'm trying to get the file_path of the image and then using the file_path to display it on the gridlayout but unfortunately, that is not working. Any help would be greatly appreciated!
This is the current image
