Clearing form field

[danielc103]

Clearing form field doesn't trigger onChanged so if setting a value there it sticks. Should onChanged be triggered for clearing form field or is there another way to clear value?

Clearing the field, by pressing the "X" icon, does trigger onChange when I test it. Can you give steps to reproduce? I've also tried specifying its controller and calling controller.clear(), which seems to work as well.

I've not specified a controller but will try that next.

After further investigation this doesn't seem to reveal itself on Android, only on iOS. Entering a date triggers, changing a date triggers, but clearing with the "X" button after does not.

Widget buildDatePicker() {
    Widget dp = Container(
      padding: EdgeInsets.fromLTRB(0, 50.0, 0, 0),
      child: Row(
        children: <Widget>[
          new Flexible(
              child: DateTimePickerFormField(
            editable: false,
            lastDate: DateTime(DateTime.now().year, DateTime.now().month,
                DateTime.now().day, DateTime.now().hour + 2),
            format: dateFormat,
            dateOnly: true,
            decoration: InputDecoration(
                prefixIcon: Icon(FontAwesomeIcons.calendar),
                labelText: 'Date',
                border: OutlineInputBorder(
                    borderSide: BorderSide(color: Colors.black))),
            onChanged: (dt) {
              print(dt);
              if (dt != null) {
                dateRoch = dt.millisecondsSinceEpoch;
              }
            },
          )),
        ],
      ),
    );

    return dp;
  }

From looking at the relevant lines, I am guessing maybe iOS doesn't allow onChange to be called if the input isn't focused?

you can user a controller instead (didn't test it yet with this plugin)

// create variable
TextEditingController date= new TextEditingController();
// assign varibale to controller
controller: date,
// access the value
date.text

I'll try the controller when I get a chance. I'll close this issue if all is working as expected.
