[Flutter Desktop] Textfield does not accept accents

On the desktop when I try to insert a letter with accents it looks as if I had pressed the button 2 times.

Ex:

~ + a = ã
~~ = ~~

But what is happening is:
~ + a = ~~ a

What happens:

What should happen:

Code example:

TextField(
     controller: TextEditingController())

Edit:

Im using logitech k380 (en_US format) and typing pt_BR, I tried do this with virtual keyboard and works well. Probably the problem is because the keyboard is in the en_US standard and my pc is set to type pt_BR.

An alternative solution until this is fixed, is to put in onChanged to identify ~~a or ^^e etc. And replace text in the controller with the correct one, ex:

onChanged: (v) {
    if (v.contains('~~a') {
         controller.text = v.replaceAll('~~a', 'ã');

    }
}

With regex I will make a better solution than comparing with all possible accents.

@Bestfastfire thanks for filing! Would you mind adding detailed repro steps for this? Specifically, which keyboard/language settings are you using? Looks like your input method/keyboard are configured with ~ and ^ as dead keys, and then you type ~a or ^e to get ã and ê respectively?

I tried with virtual keyboard and works well. Now that you mention it, I think the problem may be due to alternative keyboards since the k380 is in the en_US format and I'm trying to pt_BR.

Thanks! Can you confirm whether this started recently or whether it's always been an issue for you? There have been two major Windows keyboard input related changes recently: one that deals with individual key events, another that adds support for CJK input via IMEs, either of which I could imagine impacting multi-key character input.

Sorry, I didn't notice before, I just noticed it today.

No problem -- thanks for filing the issue. Will take a look!

I have the same problem, it was introduced in the last beta version (2.1.0-12.2.pre), the problem only occurs on windows, on MACOS it works correctly

Any predictions for solving this problem, or do you have any workarounds?

It seems there is no solution for now?

So far nothing, I am using the latest stable version of the flutter the bug continues, but it is only on this specific keyboard that I reported, it is in the EN_US standard and on windows it is set to PT_BR.

I tested it on a keyboard that is PT_BR and it worked normally

Interesting, my keyboard is PT_BR (brazilian laptop) and it doesn't work. I have exactly the problem you mentioned early.

The same for me.

I have an entire application developed, but I can't release it to production because of this issue. Any ETA to fix this bug?

If anyone needs an urgent fix to release (since the bug has been around for a long time and an official fix hasn't been released yet), I've made this ugly fix so it can work. I created a custom input and replaced it with the default one, then added that to my onChange.

if (UtilsPlatform.isWindows) {
    int pos = controller.selection.start;
    String newValue = value
        // A
        .replaceAll('´´a', 'á')
        .replaceAll('``a', 'à')
        .replaceAll('^^a', 'â')
        .replaceAll('~~a', 'ã')
        .replaceAll('´´A', 'Á')
        .replaceAll('``A', 'À')
        .replaceAll('^^A', 'Â')
        .replaceAll('~~A', 'Ã')
        // E
        .replaceAll('´´e', 'é')
        .replaceAll('``e', 'è')
        .replaceAll('^^e', 'ê')
        .replaceAll('´´E', 'É')
        .replaceAll('``E', 'È')
        .replaceAll('^^E', 'Ê')
        // I
        .replaceAll('´´i', 'í')
        .replaceAll('``i', 'ì')
        .replaceAll('^^i', 'î')
        .replaceAll('´´I', 'Í')
        .replaceAll('``I', 'Ì')
        .replaceAll('^^I', 'î')
        // O
        .replaceAll('´´o', 'ó')
        .replaceAll('``o', 'ò')
        .replaceAll('^^o', 'ô')
        .replaceAll('~~o', 'õ')
        .replaceAll('´´O', 'Ó')
        .replaceAll('``O', 'Ò')
        .replaceAll('^^O', 'Ô')
        .replaceAll('~~O', 'Õ')
        // U
        .replaceAll('´´u', 'ú')
        .replaceAll('``u', 'ù')
        .replaceAll('^^u', 'û')
        .replaceAll('´´U', 'Ú')
        .replaceAll('``U', 'Ù')
        .replaceAll('^^U', 'Û');

    /// Makes the cursor stay in the correct place
    pos -= (value.length - newValue.length);
    if (pos > newValue.length) {
      pos = newValue.length;
    }
    controller.selection =
        TextSelection.fromPosition(TextPosition(offset: pos));
    onChanged(newValue);
  } else {
    onChanged(value);
  }

It's not the best solution, and I haven't checked every possible character with accents, but it works fine for me.

Tks ReniDelonzek, I will try that!
