Hello @kwalrath ,
I would like to pass through this tutorial and report issues.

[kwalrath]

It's yours. Thank you!

[wang-ories]

OK

@kwalrath I found just one typo : a reference to pub.dev site at this line
You can follow these same steps to install any package hosted at the [Pub site](https://pub.dev;.
The close parenthesis is missing and the link is not working.

[kwalrath]

Thank you! Would you like to file an issue or just fix it?

[wang-ories]

Just fix it.

[kwalrath]

Just fix it.

Cool, I'll look for a PR from you.

Ok, great!
