Pure for DateTime not working

[uouo690]

Hello ,

`class DateInput extends FormzInput<DateTime, DateValidationError> {
const DateInput.pure() : super.pure(null);
const DateInput.dirty(DateTime value) : super.dirty(value);

@OverRide
DateValidationError? validator(DateTime value) {
return null;
}
}`

this code get me an error indicating that The argument type 'Null' can't be assigned to the parameter type 'DateTime'

How can I pure DateTime currently.

You should change the

DateTime

to

DateTime?

Sorry but which DateTime I should change ??

I edited DateValidationError? validator(DateTime value) to be DateValidationError? validator(DateTime? value) , but it still not accepting null .

The error still the same , The argument type 'Null' can't be assigned to the parameter type 'DateTime'

If there is any other way to pure DateTime please let me know

[NoamDev]

class DateInput extends FormzInput<DateTime?, DateValidationError> {
  const DateInput.pure() : super.pure(null);
  const DateInput.dirty(DateTime value) : super.dirty(value);

  @override
  DateValidationError? validator(DateTime? value) {
    return null;
  }
}

Yes , I tried that ,but it gave me this error.

`Error: The value 'null' can't be assigned to the parameter type 'DateTime' because 'DateTime' is not nullable.

• 'DateTime' is from 'dart:core'.
  const PaymentDateInput.pure() : super.pure(null);
  `

This is part of pubspec.yaml

Are you serious?
You haven't copied my entire code.
I changed it on two places.
