Need support to move the map pin to change the location

[ridsashabbir]

Based on the current implementation and documentation, the map pin can only be set to a specific location. While users can move the map, the pin remains fixed and does not update its position when dragged. I want to implement a functionality that allows users to drag the pin, updating its location to reflect the new position after dragging.

@snehmehta can you work on this? This is the Uber-style select-your-location-while-dragging-the-map experience.
