Null Safety

[DevNico]

Null safety is in the second technical preview stage with flutter core support it's therefore time to start migrating packages. I'd be happy to open a PR for Null Safety if it isn't already in the works.

Any update on this?

Hey @DevNico. If you have some free time I would be really happy if you could migrate the Package to null safety or start doing it😀
I wish you a great evening :)

[DevNico]

I actually migrated the package itself but then work and exams came in the way. I have some free time tonight will migrate the tests / example and open a PR.

[DevNico]

PR opened #211.

@DevNico

Nice work, just trying it out.

But, IMHO, it should be:

final List<Object?>? keys;

not

final List<Object>? keys;

Otherwise it's impossible to pass null as a key, which people quite often do...

[DevNico]

That obviously makes sense I just didn't have this in the codebase I tested with. Will change that when I'm at my Mac later.

@DevNico I forked your forked and will push a PR in a few minutes...

A null safe version has been releases.
