Watermark creditation (feature)

[alfanhui]

This feature should be self-fullfilling, but would be good to allow users to add their own TextSpan (text with urls) to the bottom right/left corners.

My suggestion - make a flutter_map plugin, although a simple Stack will do just fine.

If you have areas with different tile sources that need attribution, then listen on the move stream.

This is now supported via the plugin api
