Hello! thanks for the awesome package.

Dart 2.12 and flutter 2.0.0 are now in stable with the null-safety feature.

Migrating this package to null-safety would help a lot. :)

Here's an official guide from dart doc https://dart.dev/null-safety/migration-guide

Currently have the textFormfield at the bottom of the screen. So, all the suggestions appear behind the keyboard. Requesting a way to set the direction of the pop ups- either above or below the Textformfield.

Hi there. I'm fetching a list of Users from API, i have debugged every thing, data is good. The issue is i'm unable to show suggestions.

Mean while i can able to do that with static data, the suggestions are showing, but with API data filtering is working on that data, but suggestions list not showing. Any Idea..

AutoCompleteTextField<UserDataModel>( key: key, clearOnSubmit: false, suggestions: usersList, style: TextStyle(color: Colors.white70), decoration: InputDecoration( hintText: 'Search Here', contentPadding: EdgeInsets.only(left: 10.2, top: 15.0), border: InputBorder.none, hintStyle: TextStyle(color: Colors.white70), suffixIcon: IconButton( iconSize: 30.0, color: Colors.white70, icon: Icon(Icons.search), onPressed: () {}, ), ), itemFilter: (item, query) { print(item.name); return item.name .toLowerCase() .contains(query.toLowerCase()); }, itemSorter: (a, b) { return a.name.compareTo(b.name); }, itemSubmitted: (item) { setState(() { searchTextField.textField.controller.text = item.name; }); }, itemBuilder: (context, item) { return row(item); }, ),

Hello,

I've updated flutter from 1.2.x to last stable release, 1.5.4 :

[√] Flutter (Channel stable, v1.5.4-hotfix.2, on Microsoft Windows [version 6.3.9600], locale fr-FR)

No changes to the code at all. I just tried to build the appbundle again and I got some errors regarding to this plugin. Using debug, this is the error message I get when I touch the autocomplete field (without typing anything) :

I/flutter (12956): ══╡ EXCEPTION CAUGHT BY FOUNDATION LIBRARY ╞════════════════════════════════════════════════════════

I experienced this with flutter-autocomplete-textfield 1.6.4 but I updated to last version 1.6.6 and I'm facing the same issue.

I tried to rollback to flutter v1.2.2 and this issue doesn't occur.

Has someone got the same issue?

Thanks

Hi, is it possible to use a dynamic suggestion list? The idea is to retrieve a suggestion list from the backend based on what's typed by the user, so whenever the text changes, a new list is filled with suggestions. I'm using Consumer and Provider, updating the suggestion list onPointerDown, and calling notifyListeners after the retrieval of new items, but they are not displayed as suggestions. Is there anyway to contour this issue?

Hi, I would want to change the message of the "errorText" value of the decoration after the "textChanged" event.

Then i have something like this:

return AutoCompleteTextField<String>(textChanged: (text) {
setState(() { if (test.length == 0) _notGood = true; else _notGood = false;},};
[...],
decoration: InputDecoration(errorText: _notGood ? 'Empty' : null,),);

The problem is that it's not working because the decoration that i pass in parameter is passed in the constructor of the AutoCompleteTextFieldState<T> class and like that its stay in "final" i can't do nothing to change it and the build method is not refreshing the TextField.

Here : https://github.com/felixlucien/flutter-autocomplete-textfield/blob/ff8d9ead701c2c5995c5d7e6417da33eb4adad28/lib/autocomplete_textfield.dart#L152

Is there any way to bypass this or for you to make a fix ?

Thank you !

  `AutoCompleteTextField textField;
   ....
   textField.key.currentState.textField.inputFormatters.add(
    WhitelistingTextInputFormatter(RegExp("^[A-Za-z0-9]+");`

This gives null exception. Thank you!

Hi thanks for this amazing library, I was having an issue while using it and want to check if anyone knows how to solve.

I want to use the 2-3 autocomplete text fields on the same screen. But when I add it and run the app, I get the error Multiple widgets used the same GlobalKey.

This happens because the global key which is a required field cannot be used for more than 1 widget. There is a workaround by declaring our own key https://stackoverflow.com/questions/49862572/multiple-widgets-used-the-same-globalkey but autocomplete textfield do a type check and the above solution doesn't work.

For my use case, I am not using clear, is it possible to not make key required for such use cases? or is there any other suggestion.

It'd be great if we could choose whether the suggestions appear above / under the textfield. On small phones when the keyboard comes up it is kinda difficult to see the suggestions.

I want to show the selected / clicked item from suggestion list in textfield. How do I do that ? I know textfield is now exposed in latest version, but I don’t know how to use controller with autocomplete textfield. Please see my detailed question here :

https://stackoverflow.com/questions/53590156/how-to-set-value-in-autocompletetextfield

Not Showing items overlay in my view hierarchy but it manages to execute itemFilter and itemBuilder with desired results. Is there something in this layout below stopping to show results.

Parents from top Scaffold -> Stack -> Container -> Card ->ListView:

First LAyout:

Container(
 child: textFieldCities,
),

But showing the result using this layout with height set on containing Container

 Container(
    height: 300.0,
    child: textFieldStates,
  ),

But this is ugly and not desired to manually put height and the resulting overlay glides through all this 300. height

My AutocompleteTextField widget doesn't changes after some code inside decoration property changes (after setState() is called in other widget).

My hintText is not changing after the variable "nextSub" change it's value. My errorText is not changing when variable "_hasError" becomes true.

I don't know if its something about the GlobalKey or maybe is missing some setState inside the class bellow:

I am working on project based on the flutter. My requirement is like I will have an text box by entering 4 letters in that text box I need to make an API call and I need to display the suggestion list. I am using this library for displaying the suggestion. The problem is all this API call and every thing is working fine but in the devices like Samsung and devices built on MI-UI versions when user enter the text with 4 characters as expected API call is happening and displaying the suggestions list but if the user tries to delete the last two characters and tried to enter some other charterers the words is getting duplicated. This issue is only happening in the above mentioned devices but it is not happening in other devices. I had checked a lot to solve this issue finally I came to know in Samsung devices there is a setting called predictive text inside the keyboard settings if we turn that thing to off we can able to solve this issue. But how can user knows this issue and what way we can solve this issue in MI-UI devices and one more thing is there are lot of text fields available inside of my application but this issue is only happening to this text field alone . Is there any programmatic way to turn of the predictive text which is not an unique settings across all the devices ?

User enter text :-ABCD Text after deleting :-AB User tried to enter text is :-F Displayed text:- ABABF Expected output:-ABF

`SimpleAutoCompleteTextField( keyboardType: TextInputType.text, controller: searchController, key: key, textCapitalization: TextCapitalization.none, // this will be used not to captalize first letters suggestions: SearchTabView.list, textChanged: (text) async { print(text);

  if (text.length >= 4) {   // after 4 letters it will make an api call

    // this method is used to check to make an api call or need to load data from the existing list
    await suggestionsList(text, autoSuggestionRequest, context, reload,
            autoCompleteTextField)
        .then((list) {
      suggestionlist = list;
      //reload(list);
    });
  }
}`

                                    `String newText = suggestion.toString();
                                    if (submitOnSuggestionTap) {
                                    textField.focusNode.unfocus();
                                    itemSubmitted(suggestion);
                                    if (clearOnSubmit) {
                                      clear();
                                    }
                                  } else {
                                    String newText = suggestion.toString();

                                    textChanged(newText);
                                  }
                                    textField.controller.text = 
                                        appendOnTap?  textField.controller.text +newText: newText;`                                                                               

I think it would be really useful if something like the above snippet was implemented in updateOverlay , as it would allow for implementing "suggest as you type" kind of text areas with filters like the one below, which matches last typed single words with the suggestions list: itemFilter: (item, query) { return item .toLowerCase() .startsWith(query.toLowerCase().split(' ').last); },

When the text field is at the bottom of page and is pushed up by soft keyboard the suggestions overlay gets hidden by the keyboard. Is there a way to display the overlay above the text field in this scenario? Or even better have it automatically choose to display below or above based on whether it has room to fully display or not?

I can initialize textfield controller in init function. but can't do with autocomplete textfield. it shows error while running code.

this line: searchTextField.textField.controller.text = widget.custno;

log: [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: NoSuchMethodError: The getter 'textField' was called on null. E/flutter (23780): Receiver: null E/flutter (23780): Tried calling: textField E/flutter (23780): #0 Object.noSuchMethod (dart:core-patch/object_patch.dart:53:5) E/flutter (23780): #1 _EditBillPageState.setValues.<anonymous closure> package:audit_shop/pages/bill_edit_page.dart:101 E/flutter (23780): #2 State.setState package:flutter/…/widgets/framework.dart:1148 E/flutter (23780): #3 _EditBillPageState.setValues package:audit_shop/pages/bill_edit_page.dart:95 E/flutter (23780): #4 _EditBillPageState.initState

how do I resolve this?
