Как сделать обмен данными между экранами kivy python?

Здравствуйте такая проблема пишу приложение очень упрощенного IMDb на kivy. Столкнулся с проблемой что не могу обмениваться данными между экранами (Например хочу сделать так чтобы после нажатии кнопки на первом экране, label принял и вывел его или чтобы создавалось определенное количество кнопок на втором экране, исходя из того какая кнопка била нажата на первом). Помогите пожалуйста!
