A value of type 'DateTime?' can't be assigned to a variable of type 'String&#039-CodePudding

Try changing the type of the variable, or casting the right-hand type to 'String'.

TextEditingController dateInput = TextEditingController();
  @override
  void initState() {
    super.initState();
    if (widget.initialValue != null) {
       dateInput.text = widget.initialValue;
    }
  }

You can use DateFormat from intl package to format your DateTime Object to whatever format you want to display.

import 'package:intl/intl.dart';

TextEditingController dateInput = TextEditingController();
  @override
  void initState() {
    super.initState();
    if (widget.initialValue != null) {
     // Format date to whichever format you want to display
     String formattedDate = DateFormat('yyyy-MM-dd – kk:mm').format(widget.initialValue);
       dateInput.text = formattedDate;
    }
  }

You can change the initial value to string by using the toString() function like this:

dateInput.text = widget.initialValue.toString();
