Migrate to null safety

[arsamme]

@aytunch Not yet. I thought this is dependency of FlutterMap but it is not and I don't need in my projects. But I'll fork later in my free time

[arsamme]

@aytunch There is also a PR for migrating this package #7 but as @MikeMitterer said, He does not do Flutter projects anymore.
@MikeMitterer I can maintain this package if you add me to repo as maintainer.

[MikeMitterer]

Hi, no sorry - I don't with work with Dart since one or two years

[arsamme]

@MikeMitterer Will you accept PR if I do? Or we should fork and publish migrated version as new package?

[MikeMitterer]

Please fork. I even delete Dart from my HD :-))

[aytunch]

@arsamme are you planning on forking the repo?

[aytunch]

@arsamme I needed this package for flutter_map to be migrated to nnbd. If it is not a dependency for flutter_map, I am taking it out of the list I was keeping in the related issue in flutter_map. Sorry for the misunderstanding :)

@aytunch I could not find this in flutter_map's pubspec
