autocorrect | 自动给中英文之间加入合理的空格并纠正专用名词大小写

I am developing an Expenses Management App in flutter, Here I am trying to create a DateTimePicker using showDatePicker(). therefore Inside my presentDateTimePicker() function i am calling showDatePicker() method.

and I am creating a variable for selectedDate where I am not initializing it to a current value since it will change based on the user input.

inside my setState() method I saying _selectedDate = pickedDate

Still, it shows an error saying "non-nullable instance field"

I recently, too-trustingly, upgraded my Sublime Text 3 to Version 4 (Build 4107). Now auto complete behaves completely differently. It now has a pop-up from which I must select a choice - before I would just hit tab and it would choose the best option for me (I could then tab again to try for a better answer).

A concrete example: before, when I typed a word with a typo, for example "questino", I could, with my cursor directly after the o, hit tab and it would correct it to "question" automatically. Now it doesn't do that - now it would pop up a list of any longer words, such as "questions" and "questioned", and then I would have to arrow to one of them and hit enter. It wouldn't even give me "question" as an option - I would have to backspace over the n and then hit tab in order to get a popup that included that word, because not only is the popup annoying, with it requiring multiple additional keystrokes, but autocorrect no longer corrects to a word of the same length as my currently misspelled word, only to longer ones.

There are a lot of options in Preferences, including: auto_complete, auto_complete_size_limit, auto_complete_delay, auto_complete_selector, auto_complete_triggers, auto_complete_commit_on_tab, auto_complete_with_fields, auto_complete_cycle, auto_complete_use_index, auto_complete_use_history, auto_complete_preserve_order, auto_complete_trailing_symbols, and more.

Does anyone know the precise set of preferences to make it behave exactly like it used to? Or maybe there is a package that fixes it? Or maybe my next step will be reverting to the previous version.

Thanks.

I have been trying to create a search bar all day. I finally found this guide which seemed ok: https://blog.jscrambler.com/add-a-search-bar-using-hooks-and-flatlist-in-react-native/.

Hi I need to remove the underline in my TextField because it look ugly when the TextField is circular. I have sat the activeColor to transparent, but then the cursor wont show (because it's transparent). How can I remove the underline/activeColor and keep the cursor?
