Python, Kivy: How to copy to clipboard on the click of a button?

I would like to copy a text to the clipboard with the click of a button. Example code:

.py

from kivy.app import App
from kivy.uix.screenmanager import Screen, ScreenManager

sm = ScreenManager()

class main(Screen):
    def generate(self):
        text = 'Testing123456'
        #copy to clipboard

class MyApp(App):
    def build(self):
        sm.add_widget(main(name='main'))

        return sm

if __name__ == '__main__':
    MyApp().run()

.kv

<main>
    FloatLayout:
        Button:
            text: 'Generate'
            font_size: (self.height - len(self.text) * 2) / 2
            size_hint: 0.5, 0.2
            pos_hint: {'x': 0.25, 'y': 0.1}
            on_release: root.generate()

There is more of my code, but I decided to remove it because that would be off-topic. Should you need the rest of my code, feel free to tell me so.

Help is appreciated!!

Answer

You didn’t explain what is your problem but you have all in documentation: Clipboard

from kivy.core.clipboard import Clipboard
 
class main(Screen):
    def generate(self):
        text = 'Testing123456'
        Clipboard.copy(text)

And this works for me on Linux.
