PlTextLink class
A link, in a sentence or on its own.
PlTextLink(onPressed: () => open(url), child: const Text('the changelog'))
Everything about it is deliberately smaller than a button. It has no surface, no height of its own and no colour unless asked — what it has is a line under it, which is the one mark a reader already knows means "this goes somewhere".
There is no href, and that is the one real difference from the React
build: Flutter has no navigation of its own, so where a link goes is the
app's to decide. onPressed is where it is decided.
