    because text form field want assert(initialValue == null || controller == null). so you can set initialValue text into controller

    You cant use the controller and initial value at the same time.
    It’s either you use the initialValue with onChanged property or use the controller.
    If you need the controller and initial value, then you can assign your initial value to the controller.text

    final textController = TextEditingController();

void initState(){
 textController.text = 'your initial value';
 
 super.initState();
}

    Add this:

    txtEmail.text = initialValues['emailAddress'];

    Remove initialValue:

    TextFormField(
  controller: txtEmail,
  decoration: InputDecoration(
    prefixIcon: Icon(Icons.email),
    label: Text('Email Address'),
    focusedBorder: UnderlineInputBorder(borderSide: BorderSide(color: accentColor)),
   enabledBorder: UnderlineInputBorder(borderSide: BorderSide(color: iconColor))
  ),
),
