}
},
child: Text(
"REGISTER",

These is the code the last piece of code is taken from the main code.
CodePudding user response：
You added ! Before form.validate() which means only if it fails it will save. Remove the ! Mark before form.validate(). The code should be like this
if(form != null && form.validate()) {
save();
} else {
print("not ok");
}
In your form widget add this key
SingleChildScrollView (
child : Form(
key : _formKey,
child: Column(
children: [
//Textfield and buttons here
]
)
)
}
