TextField, when center aligned, shows caret in the middle when pasting text

[pablote]

Steps to Reproduce

I have a TextField like this:

child: TextField(
        onChanged: handleInputChange,
        enabled: !disabled,
        textAlign: TextAlign.center,
        style: TextStyle(color: Colors.black, fontSize: 16.0),
        obscureText: obscureText,
        decoration: new InputDecoration(
          contentPadding: const EdgeInsets.all(7.0),
          hintText: hintText,
          border: new OutlineInputBorder(
              borderRadius: new BorderRadius.all(const Radius.circular(5.0))
          )
        ),
      )

As I type, the caret is correctly shown at the end, but if I paste text from my keyboard, like my email which it remembers, the caret is shown in the middle in a weird position, not really in between characters. BTW, this does not happen when left aligned, in which case the caret is correctly advanced to the end.

This also happens when writing text if there's a space at the end.

I made a workaround to fix this problem, you can try it. @JediBurrell

_controller.addListener(() {
  if (_controller.text.length != _controller.text.trim().length) {
    _controller.text = _controller.text.trim();
  }
  _controller.selection =
    TextSelection.collapsed(offset: _controller.text.length);
});

This seems fixed for me starting with v0.10.2, can you guys verify it got fixed from 0.9.x to 0.10.x?

My flutter version is 0.11.3, and I met same problem with @JediBurrell 's situation(text if there's a space at the end), so I found a workaround. This is my flutter doctor:

I'm unable to reproduce this on the iOS simulator. I'll try on a real device soon if I can get set up. There have been several improvements to the TextField cursor recently that hopefully have fixed this.

[goderbauer]

With the example code given I cannot reproduce this anymore on neither a physical Android nor iOS device. I am tentatively closing this. If you still see this, please do not hesitate to reopen with additional details of how you reproduced it.

Looks like a dup of #24456 that was fixed recently #24456 (comment)
