如何在 kivyMD 中创建多行文本

Question

我正在尝试使用多行文本创建一个简单的应用程序，但我不断收到“无效的缩进（级别太多）”。 这是我的 main.py 文件；

from kivymd.app import MDApp


class TwoScreenApp(MDApp):
    def build(self):
        return


TwoScreenApp().run()

这是我的 .kv 文件。 我将不胜感激任何形式的帮助，谢谢。

MDScreen:
    md_bg_color: (255/255, 255/255, 255/255, 1)

MDLabel:
    halign: 'center'
    text: """With the production of the Model T automobile,
            \nHenry Ford had an unforeseen and tremendous
            \nimpact on American life. He became regarded
            \nas an apt symbol of the transition from an
            \nagricultural to an industrial America.
        """

Answer 1

这将起作用：

MDLabel:
    halign: 'center'
    text:
        """With the production of the Model T automobile,
        Henry Ford had an unforeseen and tremendous
        impact on American life. He became regarded
        as an apt symbol of the transition from an
        agricultural to an industrial America."""

出于某种原因，将多行文字放在单独的行上可以使其工作。
