it's a shame that exporting to excel is not supported.

If this is implemented + non-nullable types, then Dart will be the best language ever! Sum types (and records) are incredibly powerful constructs to model domains.

The current `TimePickerFormField` doesn't support picking minutes either, or am I missing something? It would nice to at least be able to pick minutes.

This is a great idea and I like it a lot. In fact I was hoping there would be such a package one day for flutter, mostly because I came...
