@DanielRomanMartinez, it's because I commented out part of my solution that ckecks for double spaces.

The description tells we must also check for double spaces in the middle of the string, not only at start and end of it

But part of my comment in my solution isn't correct, I just figured out that sample test works fine since it hasn't double spaces

Dart translation random tests must be fixed.

Check up strings with double spaces.

I knew it. Thought it is different enough though

Anyways I'm good with it, just will keep trying

Thank you, I did read the tests. But now I see I need to inspect them better.

I mostly like ones with detailed descriptions.

I made some changes. Is it good or should test descriptions be done more specific?

I agree and I removed the tests for input validation

I would be glad to do it, but I'm not sure I know the right way. I'll investigate

I removed quirky tests for irrelevant inputs, but I will use your advice in future, thank you for your suggestions

My bad, this is my first Kata, I will pay more attention to tests

Thank you, I will fix tests
It is mentioned in description "decimal degrees can be positive or negative", but I will try to make it more obvious

fixed it, thank you

thank you, fixing
