Thank you Johannes for the streighforward and informative explanation. Not only did I learn about Autocomplete package, I learnt about the Faker package! I bet it would go great with pagination_view 😎

Thank you Johannes for your all videos as all's videos are amazing.
This video is also amazing but please make a video with auto complete google places.
I hope you will make video and I will wait for your response on it.
Thank you.
Thanks a lot,
How can I handle querying the text entered by user in first_name, last_name & user_name altogether? I'd like to search after the user types @, so the logic can work in chat applications, when I want to tag users. Thanks!
Your content is stellar. Just curious, any way you can add secton headers for sorting? Let's say I want to order the suggestions and display

I know this is supported out of the box in React with Material components, but I'm not convinced with Flutter.
Awesome tutorial I was just thinking about it, Johannes can you please make a new tutorial for push notifications using firebase cloud functions and cloud messaging, your old tutorial uses some functions which have been deprecated. and the documentation on flutter fire site is just plain horrible.
Thanks for saving our careers.
As always brilliant ... would you make a signup, login emaillink firebase
hello Johannes. i'm use TypeAhead and working normal when I input manual from keyboard , but when try scan value from barcode scanner its not working (value scanner not display on textfield and out focus). please help me
I have a problem when using this package for flutter web in mobile view, when i tapped the textfield the keyboard showed and got dismissed, do you know what can cause this problem?
Very instructive video, thanks. I was wondering, is it possible to actually update the pattern with the suggestion clicked by the user? I have been trying that out with no luck
@@HeyFlutter I actually found a way using the controller in the textFieldConfiguration. And it is working like a charm :)
Hi johannes thanks u. I struggle on trying to hide suggestions by pressing an arrow back iconbutton with prefixIcon textfield property but want to maintain the hidesuggestiononkeyboardhide : false . I tried suggestionboxcontroller.close(); when pressing prefixIcon but nothing happened. I you can help me on this please 🙏 😥
Thank You Alioune Sakho! Follow this link: stackoverflow.com/questions/62572312/flutter-typeahead-suggestionbox-doesnt-hide
I hope you will get your answer 🙂
hello sir and really thank you for everything you do!!.. I am currently working on a form and I would like after a period of time to automatically send the user's information without having to click on a button, would you have an idea or a course that I could consult?? please!! thank you and have a good day
Thank You eric tiobo! Follow this link: stackoverflow.com/questions/65191777/in-flutter-how-to-automate-button-without-clicking-after-a-period-of-time
I hope you will get your answer 🙂
Hola, Does it work on web too ?
how can i show the suggestion box above the textfield ?
I am using the flutter_typeahead package. When I use this package to search for something, it shows me some results related to what I searched for. However, when using this package on physical devices, the last option that appears is not being clicked. For example, if I search for "A", the results that appear are "A", "AA", "AAA", but when I try to click on "AAA" on my physical device, it is not being clicked, but it can be clicked on the emulator. Also, even when there is only one result, the problem of not being able to click on the last content still occurs.
Hey, @user-rv8bi1yk7b 🙂 please go ahead and file your issue here: github.com/AbdulRahmanAlHamali/flutter_typeahead/issues
Nice video. Although you're going very fast at it. These kind of video require explanation. Great work keep it up.
Great! I want to do the same with photon.komoot.io/ . The API is there what changes do I need to make any idea ? I don't know how to use the api.

I'm trying, but because its itemBuilder, the "Suggestions:" also enter in the loop
Thank you, Daniel Oliveira! 🙂. Try to proovide enough detail with your question whenever you have any question.
@@HeyFlutter
Sorry.
I'm have to do a OpenSearch that the box widget with de the infos has something like that:
TOP SUGGESTIONS:
***here the callback return with the top suggestions list that come from the API***
SUGGESTIONS:
**here the callback return with the suggestions list that come from the API**
But, the TypeAhead use itemBuilder to build the corresponding Widget. There anyway to do something like the example above ?
English is not my first language, I'm sorry
Fun lesson! I found a slighty different way to setup device orientations in main function of main.dart:
Future main() async {
WidgetsFlutterBinding.ensureInitialized();
await SystemChrome.setPreferredOrientations([
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown
]).then((_) => runApp(MyApp())); //await setup before runApp...
}
Hey Milke, its a great video i was looking for. But how can we handle it if the data is coming from firebase firestore.
@@HeyFlutter Thank you so much :) It was really helpful.
I have noticed in the BottomNavigationBarItem that the title parm is deprecated and uses a String instead of a Text widget...
class _MainPageState extends State {
int index = 0;
@override
Widget build(BuildContext context) => Scaffold(
bottomNavigationBar: _buildBottomBar(),
body: _buildPages(),
);
Widget _buildBottomBar() => BottomNavigationBar(
backgroundColor: Theme.of(context).primaryColor,
// See bottomNavigationBarTheme in MyApp
// theme: ThemeData(
// primarySwatch: Colors.pink,
// bottomNavigationBarTheme: const BottomNavigationBarThemeData(
// selectedItemColor: Colors.white,
// unselectedItemColor: Colors.white70,
// ),
// ),
// selectedItemColor: Colors.white,
// unselectedItemColor: Colors.white70,
currentIndex: index,
items: [
BottomNavigationBarItem(
icon: _buildTextIcon(),
label: 'Network', // title parm is deprecated now uses label parm
),
BottomNavigationBarItem(
icon: _buildTextIcon(),
label: 'Local',
),
],
onTap: (int index) => setState(() => this.index = index),
);
Widget _buildTextIcon({String text = 'TypeAhead'}) =>
Text(text, style: const TextStyle(color: Colors.white));
...
Awsom
Can you give a video for playstore subscription , there is no video on youtube about it
@@HeyFlutter 😁❤️
Only first time when opening app or after installing it is working and 2nd time it' is not showing list is there where to apply set state or anything plz help me
Thank You Manisha Dharmik! Follow this link: stackoverflow.com/questions/59848513/autocomplete-not-working-correctly-in-android-studio-with-flutter-first-sugges
I hope you will get your answer 🙂
Hey Johannes, nice one but I have a little question.
The difference from this tutorial and this: ua-cam.com/video/oFZIwBudIj0/v-deo.html
From what I could understand, both do the same filter feature, but using TypeAheadField you get more tools like empty list, debounce, etc and if you do not use TypeAheadField you will need to implement all these things manually, Am I right?
not working my sdk is 2.7.0 do i really need to upgrade to 2.12? i got so many errors when i try updating my sdk
@@HeyFlutter thank you
what if the user inputs something that isn't in the autocomplete suggestions?
@@HeyFlutter but does it save?
Please add on ur idea list : login and signup with using Firestore and also fetch that data and show on textfield as a initial value to update later.
@@HeyFlutter thanks hope i learn something new.
tooppp
Thanks, Antônio Guilherme! 🙂
Flutter has itself Autocomplete widget. Can you make a video about it?
Thanks for the idea, Nhật Lê Vũ Minh! 🙂 I have added it to my list of ideas for future videos!
bro, can you help me ?

i just found out how to do this haha.
keepSuggestionsOnLoading: false
great tutorial broo . thanks btw
typeahead still doesnot support web :(
Thanks for your feedback, Debjeet Debnath! 🙂
I got one error : Error:XMLHttpRequest error.
I want to fetch data from firebase firestore
Thank you so much for the video. Ragards Janam
@@HeyFlutter Thank you so much The error is solved.
It's a missed opportunity that you didn't explain that the "TypeAhead" package is misnamed. You're talking properly about Autocomplete (provide possible additional characters based on a search space to permit abbreviations for common input text). Typeahead is a system that accepts characters from the keyboard ahead of them being able to be processed, and is such a natural flow these days that it's not seen as something that even needs a name, but clearly "TypeAhead" is nothing like "Autocomplete".
@@HeyFlutter Actually, it seems pretty easy to imeplement the same thing with Flutter Autocomplete - you have textEditingController so you can hook to changes, then make a request and update a state variable for the results.
