Override more relative links in markdown / documentation

* In the Readme.md of my package I linked the example tab of my package. Earlier this **used to work** by placing the following in the md file.

```md
[example](/example)
```
* For reference: https://pub.dev/packages/number_inc_dec

* However this link fails now and goes to `https://github.com/example`

What is the correct approach to do this? How to link the install tab and example tabs correctly. Should I just use full URL instead?
