I am watching a tutorial of flutter and i know its too basic but seems like , I can't fix this error I tried to search it but there is no proper guide to fix can someone help me in fixing this when its working fine on tutorial but not for me , and i don't get it yet its showing The property 'isEmpty' can't be unconditionally accessed because the receiver can be 'null'. Try making the access conditional (using '?.') or adding a null check to the target ('!'). this error
This is because value is of type String? and can be null. In you case you have to check if value is null.
TextFormField(
obscureText: true,
decoration: InputDecoration(
hintText: "Enter password",
labelText: "Password",
),
validator: (String? value) {
if (value != null && value.isEmpty) {
return "Password can't be empty";
}
null;
},
),
