Is there an existing issue for this?

Use case

Using the new material 3 SearchBar, it would be nice to be able to pass in the TextCapitalization to use in the TextField.

For example, if I have a SearchBar where the user can search a list of things, or create one if it doesn't exist in the list, sometimes I want those new things to begin with a capital letter as default without the user having to manually use shift to capitalize the first letter. Currently this is not possible.

Proposal

Currently this is what happens by default when you type into SearchBar without manually using shift to capitalize the first letter:

To allow this to default to "New thing", it's a really easy addition: allow passing in a TextCapitalization property:

SearchBar(
   hintText: "Search or create",
   onChanged: widget.onChanged,
   textCapitalization: TextCapitalization.sentences,
)

And apply this to the TextField in SearchBar:

                      TextField(
                        ...
                        // ADD THIS:
                        textCapitalization: widget.textCapitalization,
                      )
