无法更改 kivymd 按钮线条颜色

Question

我尝试过使用文档中提供的line_color 函数，但它没有用

from kivymd.app import MDApp
from kivy.lang import Builder 
from kivy.factory import Factory 
from kivymd.uix.selectioncontrol import MDCheckbox 
from kivy.uix.behaviors import ButtonBehavior

Root="""
#:import hex kivy.utils.get_color_from_hex      
BoxLayout:
    id:Layout_1 
    
    MDRoundFlatButton:

        size_hint:None,None
        text:"MDRoundFlatButton"
        theme_text_color: "Custom"
        font_size:16
        size_hint_y:.05
        id:btn
        line_color: 1,1,0,1
        md_bg_color:1,1,1,1
    
    MDRectangleFlatButton:
        text: "MDRECTANGLEFLATBUTTON"
        theme_text_color: "Custom"
        text_color: 1, 0, 0, 1
        line_color: 1,1,0,1

"""

class Main(MDApp):
    def build(self):
        return Builder.load_string(Root)
    


                        
Main().run()

第一个按钮所需的线条颜色为黄色

突然之间它仍然是相关的。我以这种形式配置了这些颜色，一切正常：

line_color: [255/255,255/255,255/255,1] color_active : [130/255,46/255,24/255,1] text_color : [196/255,196/255,196/255,1]
