Hi @Albert221,
Kindly note that the reason why the option is not suggested the second time you're trying to type is that you have already picked the option.

Unless I'm misunderstanding the issue.

Let me explain the issue in more detail.

When I type a in the input I have the Alpha suggestion, which is fine. I then select this suggestion so it appears in the input as this Alpha chip. Here's the problem: after that when I type another character, the chip disappears and is replaced with the a character from the very beginning. I reckon that's unwanted behavior. When I selected the chip it should stay there unless I delete it with keyboard or state.deleteChip(), not when I type more stuff into the input.

I hope you understand my issue now.

I now get the point. That would be highly undesirable behavior.

I've however tried to reproduce this issue to no avail.

Could you kindly share versions of the package or Flutter channel you're on?

I created a simple repository with some code to reproduce the issue: https://github.com/Albert221/flutter_chips_input_issue_34

Just clone the repo, run flutter pub get and then flutter run and do the following to replicate the issue:

1. Tap on the input
2. Type a
3. Tap the Alpha suggestion
4. Type a

You should see aa in the input field instead of <Alpha> a.

I've also created a Flutter Driver test, but it's not working as expected, but you can run it with

flutter drive --target=test_driver/app.dart

Here's my flutter --version:

Flutter 1.16.4-pre.50 • channel dev • https://github.com/flutter/flutter.git

@danvick were you able to correctly reproduce the issue?

Not even with your dev channel.

Hi, I was able to reproduce this bug. (on Android, iOS works fine)

Android Emulator + input from PC keyboard

Android Emulator + input from on-screen keyboard

iOS Simulator + input from PC keyboard

Flutter version output:

Flutter 1.17.0 • channel beta • https://github.com/flutter/flutter.git

I have the same problem on my android emulator.
The problem is the first character is saved on the first time.

I you type 'a' and select 'Alpha', next if you directly type 'b', the first chips disappears and there is 'ab' written on the inputchips.

Seems the text is not cleared after the first chip selection.

Thanks for shedding more light on this @bartekpacia.

I've finally been able to reproduce. So just to be clear this issue occurs only:

1. When using the Android Emulator - not on Android device
2. When using the on-screen emulator keyboard

Right?

I'll try to investigate the cause of the bug and see. I suspect it may be a Flutter issue related to #1

@danvick Thanks for investigating, but happens to me also on a physical device

It happens on physical devices too and using both physical and onscreen keyboard

Noted @Albert221 @KarnerTh.

I think I've found the culprit. Let me now work on a fix.

Not quite yet. I'll reopen this.

I have the same problem too on an Android device, but not on an Android emulator

Having the very same issue, both on Android Emulator and devices.

This issues only happens on the very first chip. I hope it throws some light on the subject

So I've been looking into this as well after experiencing this issue myself. As far as I can tell, selecting a suggestion after typing one character causes the _updateTextInputState method to update the _textInputConnection as expected, except on the next trigger of updateEditingValue, the value appears to not have taken into account the aforementioned update.

One workaround that has worked for me is to simply recreate the text input connection on every text input state change. This can be found at https://github.com/Mosc/flutter_chips_input/commit/321544efea98a056ab94e066453ad4d2b841b1b6. I'm hesitant to create a pull request because this doesn't feel like a proper fix, yet it might help out others who experience the same issue. Please don't count on my fork being available forever, but try it out by updating your pubspec.yaml as follows:

flutter_chips_input:
  git:
    url: https://github.com/Mosc/flutter_chips_input
    ref: 321544efea98a056ab94e066453ad4d2b841b1b6

The fix released in v1.9.4 unfortunately breaks flutter web usage. Using v.1.9.4 in web, one can no longer put in more than one character (tested on Chrome/MacOS).

The fix released in v1.9.4 unfortunately breaks flutter web usage. Using v.1.9.4 in web, one can no longer put in more than one character (tested on Chrome/MacOS).

That happened to me too! You can type only one character in web in all versions: 1.9.4, 1.9.0, 1.7.0

For those still using this library, I have given up on waiting for danvick and created a new fork. I've integrated all of the open PRs and fixed a bug or two. Still working on another bug related to backspace on macOS.
