Add chip after Enter key or allow to add chips programmatically

Like how most popular apps implement them. Pressing the enter key / submitting automatically adds the entered text as a chip.

How should that work?
What if the entered text does not match a suggestion, or what if the entered text matches multiple suggestions?

Yeah. I think If it doesn't match a suggestion, use it. If matches multiple suggestions, use the first one.

Your first suggestion won't work, if the suggestions are objects and not strings.
I think this is not general enough. You could implement an onSubmitted or onEditingComplete callback to do what you want. The onSubmitted isn't implemented, yet. I am open for pull requests, though.
