如何访问由kivy中的“Add”按钮创建的TextInputs中的文本输入

import kivy
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.textinput import TextInput
from kivy.uix.button import Button

class MyBoxLayout(BoxLayout):
    def __init__(self, **kwargs):

        self.orientation = 'vertical'
        self.text_inputs = []

        self.add_button = Button(text="Add")
        self.add_button.bind(on_release=self.add_text_input)
        self.add_widget(self.add_button)

    def add_text_input(self, instance):
        text_input = TextInput()
        self.text_inputs.append(text_input)
        self.add_widget(text_input)

class MyApp(App):
    def build(self):
        return MyBoxLayout()

    def get_text_inputs(self):
        text_inputs_text = []
        for text_input in self.root.text_inputs:
            text_inputs_text.append(text_input.text)
        return text_inputs_text

    def build(self):
        layout = MyBoxLayout()

        get_inputs_button = Button(text="Get Inputs")
        get_inputs_button.bind(on_release=self.get_and_print_text_inputs)
        layout.add_widget(get_inputs_button)

        return layout

    def get_and_print_text_inputs(self, instance):
        text_inputs_text = self.get_text_inputs()
        print(text_inputs_text)
