O cursor vai pra posição 0 assim que uma tecla é digitada.

[marcglasberg]

No setter do text, faça isso:

  @override
  set text(String newText) {
  if (super.text != newText) {
  value = value.copyWith(
      text: newText,
      selection: TextSelection.collapsed(offset: (newText ?? '').length),
      composing: TextRange.empty);
    }
  }

Isso resolverá um bug que ocorre quando as vezes o cursor vai pra posição 0 assim que uma tecla é digitada.

O mesmo fix pode ser aplicado no updateValue.

Hi,

Can you add the information about SO (Android or iOS) and Flutter Version? If possible, can you send a code sample?

Because I can't reproduce this (I tested in iOS and Android simulator).

[marcglasberg]

Flutter v0.9.4. It works in my simulator too. You can reproduce it only in the real phone (Galaxy S7 in my case). I have no idea why.

This happens to me too, when the mask character is inserted the cursor back to the initial position, example: 123- when the "-" is inserted the cursor backs to the initial position, the "-" is defined in the mask. Hope you can find a fix for that.

I have the same problem. This issue can be reproduce in a real device.

Hi benhurott,

I used the MaskedTextController in my custom form field and noticed the same issue. Each time when the mask character is encountered the visible cursor position resets. Then user continues typing then it appends the characters at a proper positions though. For example, consider my case where the format is a US phone number (000) 000-0000. In this case the first symbol is a mask character so when the user starts typing the phone number the first thins he notices visually is how the cursor position jumps. This needs to be addressed in order for regular users to have normal experience. For me as a developer it is not critical since I understand that I can continue typing and everything will be normal, or I know that I can fix the cursor position by tapping if needed. But average user may find it disturbing.

One more thing I noticed is that when deleting characters and it comes to the mask character the cursor position also jumps to the start.

I use Huawei P10 Pro with Android 8.0.0. Also I use current stable Flutter channel with Flutter version 1.2.1

@AlexanderArendar Exactly!!! Hope that can be fixed soon

[bhrott]

Guys I will try to fix this issue as soon as possible, but I need to test in some other devices. For now, all the simulators work fine and I have only one android device that I can't reproduce.
