prevent manual text input

[andytwoods]

Hi,
just wondering if it would be best to prevent people typing in dates by hand? Or having a little logic to disable this if wanted. The former is achievable by removing parent.controller.text.isEmpty && previousValue.isEmpty. Want a pull request?

cheers,
Andy.

void inputChanged() {
    if (//parent.controller.text.isEmpty &&
        //_previousValue.isEmpty &&
       parent.focusNode.hasFocus) {
      getDateTimeInput(context).then((date) {
        parent.focusNode.unfocus();
        setState(() {
          parent.controller.text = _toString(date, parent.format);
          setValue(date);
        });
      });
    } else if (parent.resetIcon != null &&
        parent.controller.text.isEmpty == showResetIcon) {
      setState(() => showResetIcon = !showResetIcon);
      // parent.focusNode.unfocus();
    }
    _previousValue = parent.controller.text;
    if (!parent.focusNode.hasFocus) {
      setValue(_toDate(parent.controller.text, parent.format));
    }
  }

I'm on mobile so I can't check right now, but I have a strong suspicion removing those lines will have side effects. I'll look into adding an editable option.

So I started implementing this but having a text field that is focusable but not editable isn't supported in the platform. The best option I could see was to override any changes to the text that were made manually, but then I realized instead of putting in an ugly hack, your use case shouldn't actually use this widget.

You should just use a Text or similar non-editable widget and use the platform's showDatePicker() and/or showTimePicker() when a user clicks on it.

I guess this could be used: https://stackoverflow.com/questions/44490622/disable-a-text-edit-field-in-flutter. Would be a shame to create a new package just with this feature!

Focus is currently how the input knows to show the picker dialog. I may be able to wrap it in a gesture detector. It may actually make some of the logic cleaner.

[andytwoods]

I think you can just do node.unfocus() immediately before launching the date input function.

Added support for this in #8.

Fixed in v0.1.5
