Jetpack Compose Custom UI - Speedometer with animation

Question

I want to build a custom ui to show the score in a custom view like a speedometer with an animation. Implementation would be like passing a score to the view and the needle in the view is going to animate from 0 to the score passed. The background will change according to the score passed if less than 50 its red and above 50 its red.Can anyone help me achieving this.I am attaching the ui given for reference. It could shared to social media in any format also.

In summary will need to implement this component using Canvas.

I did an initial implementation which can give you a kick-off.

Perfect implementation. I am having a small question how to change color of the arc on running like till 35 red,till 50 orange,100 to green.

Before the part commented as "Drawing Center Arc progress" you should replace the mainColor by the color in according to your logic.
