Customising MapMarker and MapMarker Popup with canvas to include text.

[Codename-Nase]

Hi all.
I tried creating a RoundRaisedButton with text, and then use it as a MapMarker and MapMarkerPopup itself instead of using an icon with source.
Creating the Button worked fine as shown below:

`from kivy.lang import Builder
from kivy.uix.behaviors import ButtonBehavior
from kivymd.uix.boxlayout import MDBoxLayout
from kivymd.app import MDApp
from kivymd.uix.behaviors import (
CircularRippleBehavior,
FakeCircularElevationBehavior,
)

KV = '''
:
size_hint: None, None
size: "25dp", "25dp"
radius: self.size[0] / 2
md_bg_color: 1, 0, 0, 1
MDLabel:
text: "[b]DC[/b]"
markup: True
halign: "center"
valign: "center"
size: root.size
pos: root.pos
font_size: root.size[0] * .6
theme_text_color: "Custom"
text_color: [1] * 4
MDScreen:

CircularElevationButton:
    pos_hint: {"center_x": .5, "center_y": .6}
    elevation: 4

'''

class CircularElevationButton(
FakeCircularElevationBehavior,
CircularRippleBehavior,
ButtonBehavior,
MDBoxLayout,
):
pass

class Example(MDApp):
def build(self):
return Builder.load_string(KV)

Example().run()`

But after adding it as a child widget under MapView to replace the regular MapMarkerPopup, the text became redundant. I don't know if i am not doing it right, or otherwise.
Below is a code of how I have tried implementing it with MapView, and any helpful pointer towards a better solution will be very much appreciated.

`from kivy.lang import Builder
from kivy.uix.behaviors import ButtonBehavior
from kivy.garden.mapview import MapMarkerPopup
from kivymd.uix.boxlayout import MDBoxLayout
from kivymd.app import MDApp
from kivymd.uix.behaviors import (
CircularRippleBehavior,
FakeCircularElevationBehavior,
)

KV = '''
:
size_hint: None, None
size: "25dp", "25dp"
radius: self.size[0] / 2
md_bg_color: 1, 0, 0, 1
MDLabel:
text: "[b]DC[/b]"
markup: True
halign: "center"
valign: "center"
size: root.size
pos: root.pos
font_size: root.size[0] * .6
theme_text_color: "Custom"
text_color: [1] * 4

MapView:
lat: 10
lon: 10
zoom: 5
CircularElevationButton:
lat: 12
lon: 12
elevation: 5
'''

class CircularElevationButton(
MapMarkerPopup,
FakeCircularElevationBehavior,
CircularRippleBehavior,
ButtonBehavior,
MDBoxLayout,
):
pass

class Example(MDApp):
def build(self):
return Builder.load_string(KV)

Example().run()`

Below is an image of what i am trying to replicate as a Marker
