Challenge is it does not get blend with the backgroung image.
Second while the color is applied on the path not able to animate the color fill something like starting from center and then applying to the entire path withTiming.
Packages used are react-native-svg and react-native-reanimated
Is there any other way to approach this in react native? Is such animation possible , if yes how can it be achieved.
